Diagnosis of HIV in adults

Examination for HIV diagnosis by antibody testing uses strategy III (3 types of antibodies with different sensitivity and specificity).

Chronology of HIV diagnosis.

• Available on HIV test A1 HIV antibody test A1 ➡ Non reactive ➡ A1 Non reactive ➡ HIV negative ➡ No risk.

• Available on HIV test A1 HIV antibody test A1 ➡ reactive ➡ HIV antibody test A2 ➡ Non reactive ➡ repeat HIV A1 and A2 tests ➡ Repeat results both Non reactive ➡ Repeat results A1 (NR) A2 (NR) ➡ HIV negative ➡ no risk.

• Available on HIV test A1 HIV antibody test A1 ➡ reactive HIV HIV antibody test A2 ➡ Non reactive ➡ repeat HIV A1 and A2 tests ➡ both reactive / reactive one ➡ HIV antibody test A3 ➡ Non reactive ➡ A1 (R) A2 (NR) A3 (NR) ➡ risk / no risk.

• Available on HIV test ➡ HIV antibody test A1 ➡ reactive ➡ HIV antibody test A2 ➡ reactive ➡ HIV antibody test A3 ➡ reactive ➡ A1 (R) A2 (R) A3 (NR) | A1 (NR) A2 (R) A3 (R) | A1 (R) A2 (NR) A3 (R) laboratorium laboratory reports ➡ intermediate ➡ clinical decisions.

• Available on HIV test ➡ HIV antibody test A1 ➡ reactive ➡ HIV antibody test A2 ➡ reactive A3 HIV antibody test A3 ➡ reactive ➡ A1 (R) A2 (R) A3 (R) laboratorium laboratory report ➡ HIV positive ➡ clinical decision.

Interpretation and follow-up of anti-HIV testing.

➡

Test Result :

• Positive.

Criteria :

• If the results of A1 are reactive, A2 is reactive and A3. reactive.

Follow-up :

• If the results of A1 are reactive, A2 is reactive and A3.

➡

Test Result :

• Negative.

Criteria :

• If A1 results are non reactive.
• If the results of A1 are reactive but at repetition A1 and A2 are non-reactive.
• If one is reactive but not at risk.

Follow-up :

• If you do not have risky behaviors, it is recommended that healthy behavior.
• If it is risky, a re-examination is recommended for a minimum of 3 months, 6 months and 12 months from the first examination to one year.

➡

Test Result :

• Intermediate.

Criteria :

• When two reactive test results.
• If only one reactive test, but has a risk or risk partner.

Follow-up :

• The test needs to be repeated with a new specimen at least after two weeks from the first examination.
• If the results remain intermediate, it is recommended by PCR examination.
• If PCR examination is not possible, rapid tests are repeated 3 months, 6 months and 12 months from the first examination. If up to one year results remain intermediate and risk factors are low, results can be declared negative.
