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 (preferred sample types, see below):
- No additional reagent is required
- For plasma samples, use EDTA tubes
For whole blood samples:
- Validated on venous and capillary blood
- Chase buffer is mandatory, ref: 7D2243 or 7D2243R (see related articles)
- For venous samples, use EDTA tubes
- For capillary samples, use the specific EDTA capillary tubes, ref. 7D2222 or 7D2227 (see related articles)
If you are considering the use of this test for another indication than pretransfusional screening (i.e. screening of chronic hepatitis B infection), additional testing should be performed to determine if the patient should be considered for antiretroviral therapy (i.e. HBeAg, HBV VL). It is recommended to consult your respective OC laboratory advisor and medical director before use outside pretransfusional screening.
