HIV – P24 Antigen: 

Why HIV P24 Antigen Test?


HIV is a Human Immunodeficiency Virus and is a sexually transmitted infection. It attacks the body’s immune system (destroys the WBCs – especially the T helper cell also known as CD4 cell since HIV replicates within it) and severely weakens the body’s immunity. If HIV is not treated, it can lead to AIDS (Acquired Immuno Deficiency Syndrome is a set of symptoms), which is potentially a life-threatening condition. HIV is caused by sexual contact(s), sex workers, multiple sex partners, blood transfusions, sharing needles, vertical transmission, childbirth (parturition), breastfeeding, oral sex, organ transplant, tattoo etc. clinical manifestations include recurring fever, headache, muscle ache and joint pain, rash, swollen lymph nodes, sore throat, cough, painful mouth ulcers, blotches on the skin (mouth, nose, eyelid etc), ulcers in genitals and anus, oral thrush (candidiasis), chronic diarrhea, weight loss, weakness, night sweats, pneumonia, Kaposi’s sarcoma etc. Some of the complications include liver (especially in hepatitis patients) and kidney diseases (HIV-Associated Nephropathy), neurological complications (HIV-Associated Neuro-cognitive Disorders: HAND) and mental disorders, wasting syndrome (resulting due to significant weight loss), a surge of opportunistic infections, HIV-1 Super-infection, long term inflammation etc. Diagnosis is performed by HIV tests like antigen or antibody test, nucleic acid test etc. p24Antigen are major HIV proteins (also called protein 24 or gag protein) can be detected even before the anti-HIV antibodies. Thus the advantage of detecting p24 in blood sample specimens are of significant importance in blood donors with accidental initial exposure to an HIV infection. At the initial exposure of HIV infection, the levels of p24 antigen are at a very high level from approximately day 10 to 1 month (since the onset of an infection).  

p24 antigen test checks for HIV antigen called p24 in the suspected patient’s blood. A positive result for p24 suggests newly infected cases of HIV, thus it helps in detecting primary HIV infection. HIV tests include antigen/antibody combination immunoassay test, differential immunoassay, ELISA Test (Monoclonal antibody test), PCR (p24 gag gene) etc. Other additional tests include viral load test, CD4 Count, Drug-Resistant Testing etc.
