What is HIV Ag Ab Combo?
Indications: Alere Determine HIV–1/2 Ag/Ab Combo is an in vitro, visually read, rapid qualitative immunoassay for the simultaneous detection of HIV-1 p24 antigen and antibodies to both HIV-1 and HIV-2 in human serum, plasma, capillary (fingerstick) whole blood or venipuncture (venous) whole blood.
What does HIV Ag AB mean?
These are called 4th generation tests or combined antibody/antigen (Ag/Ab) tests. In these tests the antigen being tested is a major HIV protein called p24. p24 (short for protein 24) is produced 2–3 weeks after infection and before antibodies are produced.
How accurate is HIV Ag Ab Combo test?
One screening test, the ARCHITECT Ag/Ab Combo assay, is described to have 100% sensitivity and >99% specificity in nonpregnant populations; however, its clinical performance in pregnancy has not been well described.
What does HIV combo mean?
The most accurate and reliable routinely used diagnostic HIV test is a laboratory test that can detect both HIV antibodies and p24 antigen. They are called combination or combo tests because they detect both substances. They are “fourth-generation” tests, with more advanced technology than the earlier generations.
What the Results Mean. A high viral load is generally considered about 100,000 copies, but you could have 1 million or more. The virus is at work making copies of itself, and the disease may progress quickly. A lower HIV viral load is below 10,000 copies.
What is the Alere determine HIV-1/2 AG/AB Combo test?
The Alere Determine™ HIV 1 / 2 Ag / Ab Combo is the first rapid point-of-care test that detects both HIV – 1 / 2 antibodies and the HIV – 1 antigen, which can appear just 12-26 days after infection¹,² HIV – 1 / 2 antibodies first appear significantly later – 20 – 45 days after infection.
What is HIV 1/o/2 ABS Qual?
HIV 1/O/2 Abs test is an Enzyme-linked immuno sorbent assay (ELISA) test that tests for the presence of HIV types 1 and 2 antibodies in the serum. A threshold value is usually set above which the result is considered positive. This threshold is what is called the index.
What is a HIV 1/2 test?
Product Specifications. The HIV-1/2 Antibody Test is an immunochromatographic assay used for the qualitative detection of antibodies against human immunodeficiency virus (HIV) in human whole blood, plasma or serum samples. Human immunodeficiency virus is a slow replicating retrovirus that causes acquired immunodeficiency syndrome (AIDS).
