Intended Use

The Epstein Barr Virus Viral Capsid-p18 Antigen (EBV VCA-p18) IgG ELISA Test is for the qualitative detection of IgG antibodies to EBV VCA in serum as an aid in the clinical laboratory diagnosis of EBV infection in patients with clinical symptoms consistent with Infectious Mononucleosis (IM). The PANBIO EBV VCA-p18 IgG ELISA should be used in conjunction with other EBV serologies.

Device Story

The EBV VCA-p18 IgG ELISA is an in vitro diagnostic test used in clinical laboratories. It utilizes a synthetically produced EBV VCA-p18 peptide antigen attached to polystyrene microwells. Patient serum is added; if IgG antibodies to VCA are present, they bind to the antigen. After washing, peroxidase-conjugated anti-human IgG is added, followed by a TMB/H2O2 substrate system. The enzymatic reaction produces a color change (blue, then yellow after acid stop) proportional to the amount of bound IgG. Results are interpreted by healthcare providers to aid in the diagnosis of EBV infection. The device is intended for use in conjunction with other EBV serologies to support clinical decision-making for patients presenting with symptoms of infectious mononucleosis.

Clinical Evidence

Clinical performance evaluated across two study sites (Australia and USA) using 490 total prospective and retrospective serum samples. Compared against the DiaSorin EBV VCA IgG ELISA and established EBV serological status. In Australian study (n=342), relative sensitivity for acute infection was 68.3% and specificity 100%. In US study (n=148), relative sensitivity for acute infection was 73.9% and specificity 96.0%. Reproducibility testing (n=27 per sample) showed total CVs ranging from 4.1% to 13.9%. Analytical specificity evaluated against a panel of 30 specimens (CMV, VZV, HSV, ANA, RF) showed 1/30 cross-reactivity.

Technological Characteristics

Enzyme-Linked Immunosorbent Assay (ELISA) using synthetic EBV VCA-p18 peptide antigen coated on polystyrene microwells. Detection via peroxidase-conjugated anti-human IgG and TMB/H2O2 substrate. Manual or automated plate processing. Results determined by absorbance measurement.

Indications for Use

Indicated for qualitative detection of IgG antibodies to EBV VCA in human serum as an aid in clinical laboratory diagnosis of EBV infection in patients with symptoms consistent with infectious mononucleosis (IM).

Regulatory Classification

Identification

Epstein-Barr virus serological reagents are devices that consist of antigens and antisera used in serological tests to identify antibodies to Epstein-Barr virus in serum. The identification aids in the diagnosis of Epstein-Barr virus infections and provides epidemiological information on diseases caused by these viruses. Epstein-Barr viruses are thought to cause infectious mononucleosis and have been associated with Burkitt's lymphoma (a tumor of the jaw in African children and young adults) and postnasal carcinoma (cancer).

## Equivalent Device:

DiaSorin EBV VCA IgG ELISA

## Device Description:

The EBV VCA-p18 IgG ELISA is an Enzyme Linked Immunosorbent Assay for the qualitative detection of IgG antibodies in human serum to EBV VCA antigen.

## Intended Use:

The Epstein-Barr Virus Viral Capsid-p18 Antigen (EBV VCA-p18) IgG ELISA is for the qualitative detection of IgG antibodies to EBV VCA in serum as an aid in the clinical laboratory diagnosis of EBV infection in patients with clinical symptoms consistent with infectious mononucleosis (IM). The PANBIO EBV VCA-p18 IgG ELISA should be used in conjunction with other EBV serologies.

#### Principle of Procedure:

Serum containing antibodies to VCA antigen, when present, combine with EBV VCA-p18 antigen attached to the polystyrene surface of the microwells. The antigen is a synthetically produced peptide. Residual serum is removed by washing and peroxidase conjugated antihuman IgG is added. The microwells are washed and a colourless substrate system, tetramethylbenzidine/hydrogen peroxide (TMB/H₂O₂) is added. The substrate is hydrolysed by the enzyme and the chromogen changes to a blue colour. After stopping the reaction with acid, the TMB becomes yellow. Colour development is indicative of the presence of EBV VCA IgG antibodies in the test sample.

### PERFORMANCE CHARACTERISTICS

### Study Site 1:

342 prospective sera of various ages and genders were tested at a private pathology laboratory in Queensland, Australia for EBV testing. The sera include the following groups: 45 seroneqative, 41 with acute infectious mononucleosis and 256 with past exposure to EBV.

These sera were tested on the PANBIO EBV VCA-p18 IgG ELISA and the DiaSorin EBV VCA IgG ELISA. The PANBIO results were compared to the EBV status of the sera to determine the sensitivity, specificity, and agreement of the assay relative to the EBV serological status (Table 1). Additionally, the DiaSorin results were compared to the EBV serological status (Table 2) and PANBIO results (Table 3), as summarised below.

## Study Site 3:

148 frozen retrospective sera of various ages and genders were submitted to a state health laboratory in Maryland USA for EBV testing. The sera include samples from the following groups: 25 seroneqative samples from patients with acute Infectious Mononucleosis, and 100 samples from patients with past exposure to EBV.

These sera were tested on the PANBIO EBV VCA-p18 IgG ELISA and the DiaSorin EBV VCA IgG ELISA. The PANBIO results were compared to the EBV status of the sera to determine the sensitivity, specificity, and agreement of the assay relative to the EBV serological status (Table 4). Additionally, the DiaSorin results were compared to the EBV serological status (Table 5) and PANBIO results (Table 6), as summarised below.

*Retesting of equivocal samples was not conducted, as the samples were unavailable.

Note: "Serological" sensitivity and specificity refers to the comparison of the PANBIO assay results to that of other assays normally used to diagnose EBV associated IM. There was not an attempt to correlate the assay's results with disease presence or absence. No judgement can be made on the comparison's accuracy to predict disease. Since the above studies were performed on a pre-selected, retrospective, populations for the assay's positive and negative predictive value may be done or inferred.

### REPRODUCIBILITY

### Study Sites 1, 4 & 5:

The reproducibility of the PANBIO EBV VCA-p18 IgG ELISA was determined by testing 8 sera 3 times each on three different days at three Australian study sites. Two sites were private pathology laboratories and the third site was PANBIO Limited. Within-run, between day, between site and total precision were estimated by analysis of variance (ANOVA Type II). The results are presented in table 7 below.

### Precision Measures (Using Cut-Off Ratio*)

All values are calculated from Ratios (Cut-off using O.D) SD = Standard Deviation; CV = Coefficient of Variation

Note: Standard Deviation results have been rounded to two decimal places for tabulation purposes.

*Cut-off Ratio is calculated as the Absorbance of the Sample divided by the Mean Absorbance of the Cut-off.

### POTENTIAL CROSS-REACTIVITY

### Study Site 5:

This study consisted of a panel of 30 specimens screened for IgG antibodies detectable by ELISA to disease types other than Epstein-Barr virus. The purpose of this study was to establish the analytical specificity of the EBV VCA-p18 IgG ELISA, through the analysis of specimens from patients with diseases that have the potential for cross-reactivity. Each of the specimens included in the study was characterised with respect to disease diagnosis and analysed with the EBV VCA-p18 IgG ELISA. Table 9 on the following page lists the crossreactivity results for each type of specimen included in the disease panel. Table 8 below provides a summary of the data presented in Table 9 (see next page).

| Disease<br>(IgG Antibodies) | Total Specimens | Positive Result |
|-----------------------------|-----------------|-----------------|
| Cytomegalovirus | 5 | (0/5) |
| Varicella zoster | 10 | (0/10) |
| Herpes simplex virus 1 | 8 | (1/8) |
| Herpes simplex virus 2 | 1 | (0/1) |
| Anti-Nuclear Antibody | 3 | (0/3) |
| Rheumatoid Factor | 3 | (0/3) |
| Total Antibody | 30 | (1/30) |

### TABLE 8 - PANBIO EBV VCA-p18 IgG CROSS-REACTIVITY SPECIMEN PANEL SUMMARY

Results indicate that one specimen (1/30) was positive when analysed with the EBV VCA-p18 IgG ELISA. The overall result of the above disease panel is consistent with good analytical specificity for the EBV VCA-p18 IgG ELISA.
