Abbott's Determine HIV tests are rapid, point-of-care diagnostic tools for screening HIV-1 and HIV-2, detecting antibodies and/or the HIV-1 p24 antigen for earlier infection detection. Key versions include the Determine HIV-1/2 Ag/Ab Combo (detects both antigen and antibodies) and Determine HIV Early Detect (4th gen for acute infection), offering quick results (around 20 mins) from whole blood, plasma, or serum, helping to diagnose infections and link patients to care globally.
