Instructions for use
Follow the instructions in the leaflet.
Provide an automatic pipette or disposable pipettes (MiniPets) and corresponding tips for the application of the 50 µl sample (see related articles below).
For serum or plasma samples
- No additional reagent is required
- For plasma samples, use EDTA tubes
For whole blood samples
- Chase buffer is mandatory, ref. 7D2243 or 7D2243R(must be ordered separately, see related articles below)
- For venous samples, use EDTA tubes
- For capillary samples, use EDTA capillary tubes, ref. 7D2227 (must be ordered separately, see related articles below)
The absence of positive and negative external controls requires to perform a control on a known blood, fresh or kept in good conditions (2 - 8ºC).
Within the MSF pretransfusional protocol, it is recommended to collect a single blood sample in a tube with anticoagulant, EDTA, in order to perform all the necessary tests (blood group determination, screening for hepatitis, HIV, syphilis and malaria).
CAUTION: As any HIV test used alone, this test has no diagnostic value. It should be confirmed by a second rapid test.
