What does the HIV 1, 2 ab test mean?

HIV 1, 2 Ab test is an initial screen test with >99% sensitivity followed by a Confirmatory test is available and must for those who screen positive. The screen test detects both HIV-1 (the commonest) and HIV-2. A DNA-based test is available for babies born to seropositive mothers.

What does HIV test results mean if positive, normal?

Normal HIV 1&2 test results. Normally most laboratories express the HIV test results with “Cut off = 1.0”. Some Labs write results as: <1.0 = negative…. >1.0 = positive…. So that all test results values under “1.0” interpreted as “0”.

How are viral load tests used to diagnose HIV?

It is used to diagnose HIV infection, in addition to Viral load tests (PCR) are used to inform treatment strategies and monitor disease progression. HIV Viral load: _50 copies/mL (PCR ‘Polymerase Chain Reaction’ test, also known as a “viral load,” is used to measure the amount of HIV in an HIV-positive person’s blood.)

What kind of HIV test do you get?

The screen test detects both HIV-1 (the commonest) and HIV-2. A DNA-based test is available for babies born to seropositive mothers. the patient’s surname, first initial, sex and date of birth, e.g. John Harris, male, d.o.b. 18/9/47, becomes HAJM180947.

How does Alere determine HIV 1 / 2 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.

Is there a test to confirm HIV 1?

HIV-1/HIV-2 antibody differentiation immunoassay. This test is to confirm HIV and find out whether you have HIV-1 or HIV-2. HIV-1 NAT (nucleic acid test).

What kind of assay is HIV 1 / O / 2 enhanced?

The ADVIA Centaur HIV 1/O/2 Enhanced assay is an antigen bridging microparticle chemiluminometric immunoassay used for the detection of antibodies to the human immunodeficiency virus type 1, including Group O, and/or type 2 in serum or plasma. Human immunodeficiency virus is the causative agent of acquired immunodeficiency syndrome (AIDS).

How is the HIV 1 / 2 antigen and antibody test done?

This includes reflex and additional tests. This test begins with HIV-1/-2 antigen and antibody screen by chemiluminescence immunoassay. If the screen result is reactive, then HIV-1/-2 antibody confirmation/differentiation test by immunochromatographic method is performed at an additional charge.
