HIV-1/HIV-2 RNA Detection, Serum

Clinical Use

Use

This test is essential for diagnosing HIV-1 and/or HIV-2 infection in individuals with indeterminate or inconclusive HIV serologic test results. It is also used for individuals suspected to be in the acute/early HIV infection stage, often referred to as the 'window period'. Additionally, this testing plays a crucial role in diagnosing HIV-1 and/or HIV-2 infection in infants under 18 months who are born to HIV-infected mothers.

Special Instructions

For qualitative detection and differentiation of HIV-1 and HIV-2 infections in individuals with indeterminate or inconclusive HIV serologic test results. It's important to perform this test when serologic testing has already been done. If not performed, the test will add automatically depending on previous results. Ship specimens frozen on dry ice. If shipment exceeds 24 hours, freeze serum specimens at -20 to -80 degrees C before shipping.

Limitations

This test is not licensed by the US FDA for screening HIV-1 in blood donors or human cells, tissues, or tissue products. An 'Undetected' result might not rule out HIV infection if the specimen was collected too soon after exposure or improperly processed/stored. It fails to detect rare HIV variants and has limitations in specimens that could contain inhibitory substances. Therefore, care must be taken in specimen processing, collection, and selection to avoid these pitfalls.
