HIV card tests (qualitative immunoassay) done after the window period are highly accurate, with sensitivity and specificity of over 99%, making them very reliable for ruling out HIV infection. The window period for modern 4th generation tests is around 4-6 weeks, and a negative result at 3 months is considered conclusive. However, for absolute confirmation, a laboratory-based 4th generation ELISA test remains the gold standard and is preferred if there is any doubt.
