Intended Use

The NOVEOS™ Specific IgE assay is an in vitro quantitative assay for the measurement of allergen specific IgE in human serum. NOVEOS Specific IgE assay is to be used with the NOVEOS Immunoassay Analyzer. It is intended for use as an in vitro diagnostic aid in the clinical diagnosis of IgE mediated allergic disorders in conjunction with other clinical findings and is to be used in clinical laboratories.

Device Story

The NOVEOS Specific IgE assay is an immunometric, chemiluminescent in vitro diagnostic test performed on the NOVEOS Immunoassay Analyzer. It utilizes fluorescent-labeled, streptavidin-coated magnetic microparticles and biotinylated allergenic capture reagents. Patient serum is incubated with the capture reagent and magnetic beads; specific IgE binds to the allergen. After magnetic separation and washing, an HRP-labeled anti-human IgE monoclonal antibody is added to form a complex. A chemiluminescent substrate is introduced, generating light proportional to the amount of bound IgE. Fluorescence is measured to correct for bead loss. Results are quantified against a calibration curve traceable to WHO reference reagent 11/234. The assay is intended for use in clinical laboratories by trained personnel to aid in diagnosing IgE-mediated allergic disorders. Results are interpreted by clinicians alongside other clinical findings to guide patient management.

Clinical Evidence

Clinical study evaluated 160-175 patients per allergen. Atopic status confirmed by oral food challenge or physician diagnosis (n=29-54); non-atopic status confirmed by ImmunoCAP (<0.35 kU/L, n=121-132). Clinical sensitivity ranged from 79.3% to 100.0% (95% CI 61.6%-100.0%); clinical specificity was 100.0% (95% CI 96.9%-100.0%) for all allergens. Bench testing included precision (CLSI EP05-A3/EP15-A3), linearity (CLSI EP06-2nd Ed), and analytical specificity (competitive inhibition).

Technological Characteristics

Immunometric chemiluminescent assay using fluorescent-labeled magnetic microparticles. Energy source: NOVEOS Immunoassay Analyzer. Dimensions/form factor: Automated analyzer system. Connectivity: Networked/standalone laboratory instrument. Sterilization: N/A (reagents). Software: Automated processing and result generation.

For use in clinical laboratories.

Regulatory Classification

Identification

A radioallergosorbent immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the allergen antibodies (antibodies which cause an allergic reaction) specific for a given allergen. Measurement of specific allergen antibodies may aid in the diagnosis of asthma, allergies, and other pulmonary disorders.

It employs fluorescent labelled magnetic, streptavidin coated microparticles which are incubated with a biotinylated allergenic capture reagent, patient sample and monoclonal anti-human IgE antibody labeled with horseradish peroxidase (Conjugate IgE). The beads are collected by use of a magnetic field to remove the liquid, and then undergo a wash step to remove unbound biotinylated allergen prior to incubation with the sample. If present in the sample, sIgE binds to the captured biotinylated allergen. After incubation, the beads are washed and subsequently incubated with an horseradish peroxidase (HRP)-labeled anti-IgE monoclonal antibody (Conjugate IgE) to form an antibody-conjugate complex that is bound to the captured biotinylated allergen. After washing away the non-bound conjugate, a chemiluminescent substrate is added to the assay mixture resulting in light generation in proportion to the amount of antibody-conjugate that has been bound to the beads. The fluorescence is used to correct for any bead loss during the assay, and the (corrected) chemiluminescence is compared to a calibration curve to provide quantification of bound sIgE. The higher the value of chemiluminescent signal detected by the instrument, the higher the amount of sIgE detected in the sample tested. The concentration of allergen specific IgE is determined from a standard curve, which is traceable to the World Health Organization (WHO) reference reagent serum Immunoglobulin E (IgE) 11/234. ## V Substantial Equivalence Information: ### A Predicate Device Name(s): ImmunoCAP Specific IgE Assay ### B Predicate 510(k) Number(s): K051218 ### C Comparison with Predicate(s): K252493 - Page 3 of 14 {3} K252493 - Page 4 of 14 | Device & Predicate Device(s): | K252775 (Candidate Device) | K051218 (Predicate Device) | | --- | --- | --- | | Device Trade Name | NOVEOS Specific IgE (sIgE) | ImmunoCAP Specific IgE | | **General Device Characteristic Similarities** | | | | Intended Use/Indications For Use | The NOVEOS Specific IgE assay is an in vitro quantitative assay for the measurement of allergen specific IgE in human serum.

The results are summarized in the following tables: K252493 - Page 6 of 14 {6} | NOVEOS Specific IgE, F013, Peanut | | | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | | Sample | Mean (kU/L) | N | Within-Run | | Between-Day | | Between-Lot | | Total | | | | | | SD | %CV | SD | %CV | SD | %CV | SD | %CV | | 1 | 0.21 | 75 | 0.01 | 6.5 | 0.01 | 4.0 | 0.00 | 1.1 | 0.02 | 7.7 | | 2 | 0.59 | 75 | 0.02 | 3.9 | 0.01 | 2.3 | 0.01 | 1.4 | 0.03 | 4.7 | | 3 | 1.60 | 75 | 0.06 | 3.7 | 0.05 | 2.8 | 0.00 | 0.0 | 0.07 | 4.7 | | 4 | 75.46 | 75 | 4.81 | 6.4 | 2.64 | 3.5 | 0.00 | 0.0 | 5.49 | 7.3 | | NOVEOS Specific IgE, F076, Bos d 4 α-lactalbumin, Milk | | | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | | Sample | Mean (kU/L) | N | Within-Run | | Between-Day | | Between-Lot | | Total | | | | | | SD | %CV | SD | %CV | SD | %CV | SD | %CV | | 1 | 0.18 | 75 | 0.01 | 6.1 | 0.01 | 4.5 | 0.00 | 2.2 | 0.01 | 7.9 | | 2 | 0.51 | 75 | 0.02 | 4.5 | 0.02 | 4.4 | 0.02 | 4.0 | 0.04 | 7.4 | | 3 | 1.12 | 75 | 0.05 | 4.6 | 0.02 | 2.1 | 0.05 | 4.6 | 0.08 | 6.9 | | 4 | 74.84 | 75 | 2.51 | 3.3 | 5.77 | 7.7 | 0.00 | 0.0 | 6.29 | 8.4 | | NOVEOS Specific IgE, F077, Bos d 5 β-lactoglobulin, Milk | | | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | | Sample | Mean (kU/L) | N | Within-Run | | Between-Day | | Between-Lot | | Total | | | | | | SD | %CV | SD | %CV | SD | %CV | SD | %CV | | 1 | 0.20 | 75 | 0.01 | 5.2 | 0.02 | 8.7 | 0.00 | 0.0 | 0.02 | 10.2 | | 2 | 0.55 | 75 | 0.02 | 4.1 | 0.02 | 3.4 | 0.00 | 0.0 | 0.03 | 5.3 | | 3 | 1.13 | 75 | 0.04 | 3.9 | 0.04 | 3.3 | 0.00 | 0.0 | 0.06 | 5.1 | | 4 | 80.09 | 75 | 4.53 | 5.7 | 7.62 | 9.5 | 0.00 | 0.0 | 8.86 | 11.1 | | NOVEOS Specific IgE, F232, Gal d 2 Ovalbumin, Egg | | | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | | Sample | Mean (kU/L) | N | Within-Run | | Between-Day | | Between-Lot | | Total | | | | | | SD | %CV | SD | %CV | SD | %CV | SD | %CV | | 1 | 0.13 | 75 | 0.01 | 9.3 | 0.02 | 11.8 | 0.00 | 0.0 | 0.02 | 15.1 | | 2 | 0.53 | 75 | 0.02 | 4.1 | 0.02 | 2.8 | 0.01 | 1.3 | 0.03 | 5.2 | | 3 | 1.58 | 75 | 0.06 | 3.6 | 0.02 | 1.2 | 0.01 | 0.7 | 0.06 | 3.8 | | 4 | 85.61 | 75 | 4.01 | 4.7 | 3.99 | 4.7 | 0.00 | 0.0 | 5.65 | 6.6 | 2. Linearity: Linearity of each NOVEOS Specific IgE assay was evaluated in accordance with the CLSI guideline I/LA20-A3. Three sets of linearity dilution panels including six levels were prepared by using three positive human serum samples (low, mid, and high) diluted with one negative serum sample. Three dilution panels overlapped and created the full dilution panel. Testing was performed using one lot of each NOVEOS Specific IgE Assay in four replicates of each sample. The linearity data analysis was performed individually for each NOVEOS Specific IgE Assay in accordance with the CLSI EP06, $2^{\text{nd}}$ Edition. For each sample level in the dilution panels, the mean value of the measured values, the predicted value and the % deviation from linearity were calculated. K252493 - Page 7 of 14 {7} The linear range and the claimed analytical meaning range for each NOVEOS Specific IgE are shown in the table below: | NOVEOS Specific IgE | Tested Linear Range | Analytical Measuring Range | | --- | --- | --- | | F013, Peanut | 0.05 – 103.76 kU/L | 0.10 – 100.0 kU/L | | F076, Bos d 4 α-lactalbumin, Milk | 0.09 – 98.91 kU/L | 0.10 – 98.0 kU/L | | F077, Bos d 5, β-lactoglobulin, Milk | 0.05 – 132.05 kU/L | 0.10 – 100.0 kU/L | | F232, Gal d 2 Ovalbumin, Egg | 0.08 – 128.31 kU/L | 0.10 – 100.0 kU/L | ## 3. Analytical Specificity/Interference: ### a. Inhibition study: Immunological specificity of each NOVEOS Specific IgE assay was verified through competitive inhibition study according to the CLSI guideline I/LA20-A3. Positive samples with specific IgE concentration used in the study include: 1.64 kU/L for F013, Peanut; 5.39 kU/L for F076, Bos d 4 α-lactalbumin, Milk; 2.39 kU/L for F077, Bos d 4 α-lactalbumin, Milk and 2.21 kU/L for F232, Gal d 2 Ovalbumin, Egg. The allergen solution (inhibitor) was diluted 1:1 into the positive serum sample to achieve a starting concentration of 50 µg/mL for F013, F076, F077, and F232. The sample solution was serially diluted in two-fold increments and each diluted sample was evaluated for dose-dependent inhibition in four replicates using one lot of NOVEOS sIgE Assay for F076, F077, and F232, and two lots for F013. The results of the dose-dependent inhibition study demonstrated concentration-dependent inhibition for all allergens tested, with substantial inhibition observed at the following inhibitor concentrations: 86% inhibition for F013 at 40 µg/mL, 87% inhibition for F076 at 50 µg/mL, 92% inhibition for F077 at 50 µg/mL, and 90% inhibition for F232 at 1.5625 µg/mL. For the NOVEOS Specific IgE Assays F013, F076, F077, and F232 the related and unrelated allergens tested were as follows: - For F013, Peanut, the related allergen F202 (Cashew Nut) and the unrelated allergens D072 (Tyrophagus putrescentiae), D201 (Blomia tropicalis), I006 (German Cockroach), and M012 (Aureobasidium pullulans) were tested as potential inhibitors at a final concentration of at least ten times the concentration of F013 at which &gt;85% inhibition was achieved. All allergen inhibitors were spiked into the positive serum sample at a 1:1 dilution and evaluated with one lot of NOVEOS Specific IgE Assay, F013. The results of the single-dose inhibition studies using one related allergen (F202) and four unrelated allergens showed ≤15% inhibition at a test concentration of 400 µg/mL. The inhibition studies indicate that the NOVEOS Specific IgE Assay, F013 contains the immunologically relevant allergen. - For F076, Bos d 4 α-lactalbumin, Milk, the related allergen F422 (Ara h 1, Peanut) and the unrelated allergens E221 (Can f 3 Dog Serum Albumin), M218 (Asp f 1, K252493 - Page 8 of 14 {8} Aspergillus fumigatus), and T215 (Bet v 1 PR-10, Birch) were tested as potential inhibitors at a final concentration of at least ten times the highest concentration of F076 that achieved &gt;85% inhibition. All allergen inhibitors were spiked into the positive serum sample at a 1:1 dilution and evaluated with one lot of NOVEOS Specific IgE Assay, F076. The results of the single-dose inhibition studies using one related allergen (F422) and three unrelated allergens showed ≤15% inhibition at test concentrations of 600 μg/mL for F422, 1970 μg/mL for E221, 660 μg/mL for M218, and 1200 μg/mL for T215. The inhibition studies indicate that the NOVEOS Specific IgE Assay, F076 contains the immunologically relevant allergen. - For F077, Bos d 4 α-lactalbumin, Milk, the related allergen F422 (Ara h 1, Peanut) and the unrelated allergens E221 (Can f 3 Dog Serum Albumin), M218 (Asp f 1, Aspergillus fumigatus), and T215 (Bet v 1 PR-10, Birch) were tested as potential inhibitors at a final concentration of at least ten times the highest concentration of F077 that achieved &gt;85% inhibition. All allergen inhibitors were spiked into the positive serum sample at a 1:1 dilution and evaluated with one lot of NOVEOS Specific IgE Assay, F077. The results of the single-dose inhibition studies using one related allergen (F422) and three unrelated allergens showed ≤15% inhibition at test concentrations of 600 μg/mL for F422, 1970 μg/mL for E221, 660 μg/mL for M218, and 1200 μg/mL for T215. The inhibition studies indicate that the NOVEOS Specific IgE Assay, F077 contains the immunologically relevant allergen. - For F232, Gal d 2 Ovalbumin, Egg, the related allergen F076 (Bos d 4, α-lactalbumin, Milk) and the unrelated allergens E221 (Can f 3 Dog Serum Albumin), M218 (Asp f 1, Aspergillus fumigatus), and T215 (Bet v 1 PR-10, Birch) were tested as potential inhibitors at a final concentration of at least ten times the lowest concentration of F232 that achieved &gt;85% inhibition. All allergen inhibitors were spiked into the positive serum sample at a 1:1 dilution and evaluated with one lot of NOVEOS Specific IgE Assay, F232. The results of the single-dose inhibition studies using one related allergen (F076) and three unrelated allergens showed ≤15% inhibition at a test concentration of 15.625 μg/mL. The inhibition studies indicate that the NOVEOS Specific IgE Assay, F232 contains the immunologically relevant allergen. b. Interference: i. Endogenous Substance Interference: The effect of the presence of elevated levels of human serum albumin, hemoglobin, triglycerides, conjugated bilirubin, and unconjugated bilirubin in serum samples was evaluated by testing three serum sample pools (one negative, one near the cut-off, and one positive) spiked with varying levels of each interferent. Testing was conducted with seven replicates in one assay run using one lot each of the NOVEOS sIgE assays for F013 (Peanut), F076 (Bos d 4 α-lactalbumin, Milk), F077 (Bos d 5 β-lactoglobulin, Milk), and F232 (Gal d 2 Ovalbumin, Egg). The % Interference for each sample spiked with the potential interfering substance was calculated by comparing its result to that of the corresponding control sample spiked with an equal volume of the solvent without the interfering substance. No interference was noted for samples containing human serum albumin up to 120 g/L, hemoglobin up to 200 K252493 - Page 9 of 14 {9} mg/dL, intralipid up to 3000 mg/dL, conjugated bilirubin up to 30 mg/dL, and unconjugated bilirubin up to 20 mg/dL. ii. Exogenous Substance Interference: Refer to K200825. c. Cross-reactivity: The potential cross-reactivity of non-IgE (IgA, IgD, IgG, and IgM) to the NOVEOS sIgE assays was evaluated in K200825. 4. Assay Reportable Range: The assay reportable range is the same as the claimed analytical measuring range for each NOVEOS sIgE as shown in the table below: | NOVEOS Specific IgE | Assay Reportable Range/ Analytical Measuring Range | | --- | --- | | F013, Peanut | 0.10 – 100.0 kU/L | | F076, Bos d 4 α-lactalbumin, Milk | 0.10 – 98.0 kU/L | | F077, Bos d 5, β-lactoglobulin, Milk | 0.10 – 100.0 kU/L | | F232, Gal d 2 Ovalbumin, Egg | 0.10 – 100.0 kU/L | 5. Traceability, Stability, Expected Values (Controls, Calibrators, or Methods): a. Traceability: The IgE calibrators are traceable to the World Health Organization (WHO) third International Standard 11/234 of Human Serum Immunoglobulin E. b. Kit stability: The stability study was conducted in accordance with CLSI EP25-A2. Shelf-life stability: A real-time stability study for the NOVEOS Specific sIgE Capture Reagent Pack of F013, F076, F077, and F232 stored at 2–8°C is ongoing using three lots. The test was planned by testing two positive samples and one negative sample. An accelerated stability study was conducted with two positive samples and one negative sample using three lots of each Capture Reagent stored at 37°C to show potential 36 months stability of these Capture Reagent if stored as 2–8°C. All other reagents required to perform specific IgE testing on the NOVEOS system are not allergen specific and the shelf-life stability of these reagents has been previously established per K182479 and K191510 (for the Fluo Beads reagent). On-board stability: A study was performed on one instrument using three samples (two positive and one negative or low-level sample) using at least one lot of each NOVEOS Specific IgE Capture Reagent Pack F013, F076, F077, and F232 stored on the NOVEOS Immunoassay Analyzer. The test was done by testing each sample in three replicates at K252493 - Page 10 of 14 {10} Day 0 and scheduled timepoints of 15, 28, and 29 days. The timepoints were chosen to at minimum have a penultimate (Tn) and ultimate (Tn+1) timepoint. The result supports that the allergen specific capture reagent is stable for 28 days stored on-board. The result supports that the allergen specific capture reagent is stable for 28 days once opened and stored at 2-8°C. The on-board stability for all the other assay components has been previously established per K182479. *Open-vial stability*: Accelerated open vial stability studies were performed using one lot for F013, F076, F077, and F232 capture reagents. The studies evaluated opened capture reagent vials filled to 100% and 50% fill volume, stored at 37°C for up to 10 days to simulate the stress of real-time aging. The allergen specific capture reagent is stable for 15 days once opened and stored at 2-8°C. ## 6. Detection Limit: The limit of blank (LoB), limit of detection (LoD), and limit of quantitation (LoQ) of each NOVEOS sIgE assay, i.e., F013, F076, F077, and F232 on the NOVEOS Immunoassay Analyzer were determined according to CLSI guideline EP17-A2. The LoB was determined by testing four analyte-free human serum samples in replicates of five per run, over three runs, with no more than one run per day, using two lots of each capture reagent on one NOVEOS Immunoassay Analyzer. The LoB was estimated as the 95th percentile of the 60 measurements for each of the two lots tested. The LoD was determined by testing protocol summarized in the table below and calculated based on CLSI EP17-A2: | NOVEOS sIgE | No. of Samples | No. of Lots | No. of Analyzers | Testing Protocol | | --- | --- | --- | --- | --- | | F013 | 4 | 2 | 1 | 4 samples x 5 replicates/run x 3 runs (n= 60) | | F076 | 4 | 2 | 1 | Lot 1: 4 samples x 5 replicates/run x 3 runs (n= 60) Lot 2: 4 samples x 5 replicates/run x 3 runs (n= 64*) | | F077 | 4-5 | 2 | 1 | Lot 1: 5 samples x 5 replicates/run x 3 runs (n=75) Lot 2: 4 samples x 5 replicates/run x 3 runs (n= 60**) | | F232 | 5 | 2 | 1 | 5 samples x 5 replicates/run x 3 runs (n= 75) | * A single replicate for a sample dropped on a run so an additional run was performed for lot 2 ** One sample was excluded due to carryover The LoQ was determined by testing four low IgE samples with three replicates per run over three testing days using two lots of each capture reagent on one NOVEOS Immunoassay Analyzer resulting in a total of 36 replicates across all samples per lot. Data analysis was performed according to the precision profile method using within-lab precision results. The LoQ is defined as the mean value of the lowest sample which fulfills the specification for the total within-laboratory imprecision (&lt;20%CV). The claimed LoB, LoD, and LoQ are based on the highest value obtained from the two lots tested and are summarized in the table below. K252493 - Page 11 of 14 {11} | NOVEOS Specific IgE | LoB (kU/L) | LoD (kU/L) | LoQ (kU/L) | | --- | --- | --- | --- | | F013, Peanut | 0.07 | 0.08 | 0.10 | | F076, Bos d 4, α-lactalbumin, Milk | 0.07 | 0.08 | 0.10 | | F077, Bos d 5 β-lactoglobulin, Milk | 0.07 | 0.08 | 0.10 | | F232, Gal d 2 Ovalbumin, Egg | 0.07 | 0.08 | 0.10 | 7.

Matrix Comparison: Not Applicable C Clinical Studies: 1. Clinical Sensitivity and Specificity: For each NOVEOS Specific IgE assay, the clinical performance was evaluated by comparing the test results from a cohort of atopic and non-atopic samples to the clinical diagnosis of allergy. The atopic samples were from different U.S. and EU vendors with a clinical history of allergy-like symptoms, and identified as positive by oral food challenge (OFC) or diagnosed positive by a physician. The non-atopic samples were from donors with no reported allergy and were deemed negative by ImmunoCAP testing (&lt;0.35 kU/L). The sIgE test results are expressed as positive or negative using a cut-off of 0.35 kU/L. The clinical sensitivity and clinical specificity for each NOVEOS Specific IgE Assay are summarized in the following tables: | | Clinical Diagnosis | | | | | --- | --- | --- | --- | --- | | | | Atopic | Non-atopic | Total | | NOVEOS Specific IgE, F013, Peanut | Positive | 49 | 0 | 49 | | | Negative | 5 | 121 | 126 | | | Total | 54 | 121 | 175 | | Sensitivity: 90.7% (49/54) (95% CI: 80.1 – 96.0%) Specificity: 100.0% (121/121) (95% CI: 96.9 – 100.0%) | | | | | K252493 - Page 12 of 14 {12} | | Clinical Diagnosis | | | | | --- | --- | --- | --- | --- | | | | Atopic | Non-atopic | Total | | NOVEOS Specific IgE, F076, Bos d 4, α-lactalbumin, Milk | Positive | 24 | 0 | 24 | | | Negative | 5 | 132 | 137 | | | Total | 29 | 132 | 161 | | Sensitivity: 82.8% (24/29) (95% CI: 65.5 – 92.4%) Specificity: 100.0% (132/132) (95% CI: 97.2 – 100.0%) | | | | | | | Clinical Diagnosis | | | | | --- | --- | --- | --- | --- | | | | Atopic | Non-atopic | Total | | NOVEOS Specific IgE, F077, Bos d 5 β-lactoglobulin, Milk | Positive | 23 | 0 | 23 | | | Negative | 6 | 132 | 138 | | | Total | 29 | 132 | 161 | | Sensitivity: 79.3% (23/29) (95% CI: 61.6 – 90.2%) Specificity: 100.0% (132/132) (95% CI: 97.2 – 100.0%) | | | | | | | Clinical Diagnosis | | | | | --- | --- | --- | --- | --- | | | | Atopic | Non-atopic | Total | | NOVEOS Specific IgE, F232, Gal d 2 Ovalbumin, Egg | Positive | 34 | 0 | 34 | | | Negative | 0 | 126 | 126 | | | Total | 34 | 126 | 160 | | Sensitivity: 100.0% (34/34) (95% CI: 89.8 – 100.0%) Specificity: 100.0% (126/126) (95% CI: 97.0 – 100.0%) | | | | | All samples used to evaluate the clinical performance of each of the above NOVEOS Specific IgE assays were also tested with the corresponding predicate device, ImmunoCAP specific IgE. Clinical specificity of both assays showed 100%, and clinical sensitivity for two assays are shown in the following table: | | Clinical Sensitivity | | | --- | --- | --- | | | NOVEOS Specific IgE | ImmunoCAP Specific IgE | | F013, Peanut | 90.7% | 100.0% | | F076, Bos d 4 α-lactalbumin, Milk | 82.8% | 89.7% | | F077, Bos d 5, β-lactoglobulin, Milk | 79.3% | 79.3% | | F232, Gal d 2 Ovalbumin, Egg | 100.0% | 100.0% | 2. Other Clinical Supportive Data (When 1. and 2. Are Not Applicable): Not Applicable D Clinical Cut-Off: The clinical cut-off of the assay is 0.35 kU/L. The interpretation of results of the assay uses the following classification system: K252493 - Page 13 of 14 {13} | Class | Concentration (kU/L) | Interpretation | | --- | --- | --- | | 0 | <0.35 | Negative | | I | 0.35 to <0.70 | Positive with increasing sIgE concentration | | II | 0.70 to <3.50 | | | III | 3.50 to <17.50 | | | IV | 17.50 to <50.00 | | | V | 50.00 to <100.00 | | | VI | ≥100 | | # E Expected Values/Reference Range: The expected value is $&lt; 0.35 \, \mathrm{kU/L}$ (negative) for a specific allergen in an apparently healthy (non-atopic) person. Each laboratory should establish its own expected value/reference range. The reference range of NOVEOS Specific IgE assay for F013 (Peanut), F076 ( $\alpha$ -lactalbumin), F077 ( $\beta$ -lactoglobulin), and F232 (Ovalbumin) in the normal population was evaluated based on the data collected in clinical studies which tested samples from apparently healthy subjects including: 121 non-atopic samples for F013; 132 non-atopic samples for F076; 132 non-atopic samples for F077; and 126 non-atopic samples for F232 tested by corresponding NOVEOS Specific IgE assay. All samples tested with the NOVEOS Specific IgE assays were below 0.35 kU/L. # VIII Proposed Labeling: The labeling supports the finding of substantial equivalence for this device. # IX Conclusion: The submitted information in this premarket notification is complete and supports a substantial equivalence decision.
