Regulatory Classification
Identification
A quality control material (assayed and unassayed) for clinical chemistry is a device intended for medical purposes for use in a test system to estimate test precision and to detect systematic analytical deviations that may arise from reagent or analytical instrument variation. A quality control material (assayed and unassayed) may be used for proficiency testing in interlaboratory surveys. This generic type of device includes controls (assayed and unassayed) for blood gases, electrolytes, enzymes, multianalytes (all kinds), single (specified) analytes, or urinalysis controls.

IMMULITE 2000 AFP CVM: Each CVM level was tested for 9 runs and 3 replicates per run for a total of 27 replicates. Three different reagent kit lots and 5 different instruments were used to gain 27 replicates. The CVMs dose values were generated using a curve generated by assigned reference calibrators. The analyte values were calculated based on the recovered values for each run on each instrument independently. CVM values were then averaged across all systems. The Guideline Range (95% confidence interval) for each CVM level was established based on the Target Mean and ± 2 Standard Deviation (SD). The expected values are provided in the IMMULITE 2000 CVM Calibration Verification Material lot-specific value card. The values in the table below can be considered as guidelines.

The Guideline Range (95% confidence interval) for each CVM level was established based on the Target Mean and ± 2 Standard Deviation (SD). The expected values are provided in the IMMULITE 2000 CVM Calibration Verification Material lot-specific value card. The values in the table below can be considered as guidelines.
| BR-MA CVM Level | Target Mean (U/mL) | SD (U/mL) | Guideline Range (U/mL) | |

Three different reagent kit lots and 9 different instruments were used to gain 27 replicates. The CVM values are calculated based on the recovered values for each run on each instrument independently. CVM values are then averaged across all systems. The Guideline Range (95% confidence interval) for each CVM level was established based on the Target Mean and ± 2 Standard Deviation (SD). The expected values are provided in the IMMULITE 2000 CVM Calibration Verification Material lot-specific value card. The values in the table below can be considered as guidelines.

iii. Stability:
The stability study was conducted to validate shelf life claim for the IMMULITE 2000 AFP CVM, IMMULITE 2000 BR-MA CVM and IMMULITE 2000 OM-MA CVM, to ensure that the CMVs maintains optimal product performance on IMMULITE 2000 platforms throughout the established shelf life of the CVM. The IMMULITE 2000 AFP CVMs are stable up to 3.5 years when stored frozen at -20°C prior to opening. The IMMULITE 2000 BR-MA CVMs are stable up to 4.5 years when stored frozen at -20°C prior to opening. The IMMULITE 2000 OM-MA CVMs are stable up to 9 years when stored refrigerated at 2-8°C prior to opening.
iv. Matrix effect:
The Matrix Effects Studies were performed to describe any significant difference between the IMMULITE 2000 AFP CVM, IMMULITE 2000 BR-MA CVM and IMMULITE 2000 OM-MA CVM and typical patient samples in terms of conditions known to cause analytical error.
IMMULITE 2000 AFP CVM: A stock solution of AFP antigen was used to prepare the spiking solutions for studying matrix effects. Three spiking solutions were prepared from stock solution. Each spiking solution was spiked into matrix (Bovine Serum) and patient sample (1 part spiking solution to 19 parts matrix or sample) to generate three sets of spiked samples (concentrations at 9.91 IU/mL, 29.76 IU/mL and 67.81 IU/mL).
IMMULITE 2000 BR-MA CVM: A stock solution of BR-MA antigen (CA15.3) was used to prepare the spiking solutions for studying matrix effects. Three spiking solutions were prepared from stock solution. Each spiking solution was spiked into matrix (Bovine Serum) and patient sample (1 part spiking solution to 19 parts matrix or sample) to generate three sets of
{8}
spiked samples (concentrations at 282 U/mL, 617 U/mL and 1,168 U/mL).
IMMULITE 2000 OM-MA CVM: A stock solution of OM-MA antigen (CA125) was used to prepare the spiking solutions for studying matrix effects. Three spiking solutions were prepared from stock solution. Each spiking solution was spiked into Bovine protein/buffer matrix and patient sample (1 part spiking solution to 19 parts matrix or sample) to generate three sets of spiked samples (concentrations at 627 U/mL, 1,207 U/mL and 2,408 U/mL).
The spiked AFP, BR-MA and OM-MA samples were run in their respective assays on IMMULITE 2000 platform. The % recovery of antigen in the spiked matrix was compared to the % recovery in the spiked patient sample. Each of the tested samples met the acceptance criteria: the grand mean of the recoveries must be within 100% ± 10% of the expected value with no mean recovery being more than 100% ± 15%.
