![]() ![]() ![]() HIV inconclusive as positive result in screening assay only and not confirmed in one further assay.If the result is reproducible the clinical comments to report are: If the result is not reproducible then report as for result 1. We recommend repeating the screening assay to ensure the result is reproducible. We recommend reporting comments only, not individual test results. Use these comments when the first sample was inconclusive and the repeat sample 2 weeks later gives the same results. the sample gives the same reactivity as the previous one: the absence of serological change and the continued negative results in the confirmatory assays indicate that the result in the screening assay is non-specific.no evidence of HIV infection and no action required.probable false positive in the screening assay: to confirm please repeat 2 weeks from the date of this sample.HIV inconclusive as positive result in screening assay only and not confirmed in 2 further assays.If the result is reproducible then the clinical comments to report are: It is advisable to send a sample to the reference laboratory before reporting unless the woman is a late booker. Result 4Īlthough these results suggest co-infection, in practice this is very rare and it’s more likely the assay was unable to differentiate antibodies as HIV-1 or HIV-2. If HIV-2 antibody is detected as a new diagnosis, referral to a reference laboratory that undertakes HIV-2 specific serology and HIV-2 RNA testing for confirmation is advised. refer to multi-disciplinary team for full clinical evaluation.please offer testing at any time in pregnancy if the woman has a new exposure risk or develops relevant symptoms.negative at time the screening sample was taken.When screening tests for all 3 infections are negative/not detected add the following comments: HIV-1 and HIV-2 antibody and p24 antigen not detected.Not detected (reflex test on original screening sample)ĭetected (repeat sample as follow-up to results in 11)įor this result, the clinical comments to report are: HIV antibody detected but p24 antigen not detected Not detected (separate follow-up EDTA sample)ĭetected (repeat sample as follow-up to results in 9) HIV-1 RNA (if performed as reflex test or on further sample)ĭetected (repeat sample as follow-up to results in 5)ĭetected (following flowchart for sequential confirmatory testing)ĭetected (repeat sample as follow-up to results in 7) For each set of results, clinical comments for reports and recommendations for the laboratory team are outlined below the table. The table below shows different testing results. ![]()
