HIV Confirmation

Which test do we use?

Geenius HIV 1/2 Confirmatory Assay (BioRad).

When a confirmation is requested, two duo-screening assays (Ag/Ab) (and HIV 1/2 antigen detection if necessary) will automatically be performed as well.

Sampling instructions

At least 1,5-2 ml serum.

Storage conditions

Serum or mother tubes should be kept in the refrigerator at (2-8°C) and sent at room temperature.

Important advice

Use the request form for a confirmation.

Make sure the samples have not been:

• bacteriologically contaminated
• frozen and defrosted repeatedly
• hemolyzed

All children < 18 months of age of seropositive mothers are diagnosed by HIV DNA PCR and HIV RNA viral load, and not through HIV serology.
