HIV Combo EIA
| Test Name: | GS HIV Combo Ag/Ab EIA |
| Test Methodology: | Enzyme immunoassay for the simultaneous detection of HIV p24 antigen and antibodies to HIV-1 and HIV-2. |
| Test to be Performed: | HIV Combo EIA |
| CPT: | 87389 |
| Reflex Testing Criteria: | Repeatedly reactive results are reflexed to HIV Geenius test to distinguish between HIV-1 and HIV-2. Discordant results are reflexed to HIV-1 Qualitative test. |
| Pre-Approval Required: | N/A |
| Accepted Specimens: | Serum (serum tube or SST) |
| Specimen Stability: | Samples should be tested within 7 days of collection. Samples may be stored for up to 2 days at room temperature. Optimum storage: 2-8°C. For samples that require longer that 7 days storage, serum must be removed from the red cells and stored at -20°C or below. Samples should not be used if they have more than 4 freeze-thaw cycles. |
| Storage/Transport Conditions: | Specimens should be stored and transported at 2-8°C. Sufficient frozen cold packs in an insulated cooler can be used to maintain this temperature. Specimens may be transported at room temperature (15-25°C) if delivered to the lab within 48 hours from collection time. |
| Turnaround Time: | 7 business days |
| Reference Range: | Non-reactive |
| Comments: | A negative test result does not preclude the possibility of exposure to or infection with HIV-1 and/or HIV-2. All specimens with a preliminary positive result from any rapid HIV test conducted in a CLIA-waived setting will be tested using the HIV Combo EIA as the first step of the Laboratory HIV Testing Algorithm. |
