The HIV I & II test is a blood test used to detect infection with Human Immunodeficiency Virus types 1 and 2:
- HIV-1 is the most common and widespread form globally.
- HIV-2 is less common, primarily found in West Africa but still clinically important.
Tests used may include:
- Rapid antibody tests
- 4th generation ELISA (detects both p24 antigen and HIV antibodies)
- Western blot or NAT (nucleic acid testing) for confirmation
❓ Why is the Test Done?
To:
- Diagnose HIV infection (primary or chronic)
- Screen blood donors, pregnant women, and high-risk individuals
- Monitor HIV exposure risk (needle injury, unprotected sex, etc.)
- Aid in early detection, treatment initiation, and prevent transmission
📊 Normal Range / Interpretation
Result | Interpretation |
|---|---|
Non-reactive / Negative | No evidence of HIV infection. May still be in the window period. |
Reactive / Positive | Likely HIV infection – requires confirmatory testing (e.g., Western blot, NAT) |
Indeterminate | Repeat test or use confirmatory methods (PCR, antigen testing) |
Most accurate results after 3–4 weeks of exposure using 4th generation tests.
🧠 Associated Organs & Conditions
System | Conditions |
|---|---|
Immune system | Destruction of CD4+ T-cells, leading to AIDS |
Opportunistic infections | TB, candidiasis, toxoplasmosis, CMV, PCP, etc. |
CNS | HIV-associated neurocognitive disorder |
Skin | Rashes, herpes zoster, Kaposi’s sarcoma |
📈 Interpretation Timeline
Time Since Exposure | Recommended Test |
|---|---|
<10 days | Nucleic Acid Test (NAT) – RNA detection |
10–20 days | p24 antigen (4th gen ELISA) becomes detectable |
>3 weeks | HIV antibodies (IgM/IgG) become detectable |
>3 months | Nearly all infected individuals will test positive by antibody tests |

- HIV Western Blot or Immunoblot – Confirmatory test
- Hepatitis B & C testing – Often co-screened
- Syphilis, VDRL, HBsAg, HCV – Common in STD panels
- HIV Drug Resistance Genotyping – For treatment planning
