Q. What is the cut-off value for ELISA test?
Hello doctor,
I have some queries about HIV, ELISA/ECLIA TEST. What is the cut-off for this test? In some lab reports, they do not mention the cut off rate. They just mention if it is reactive or non-reactive. In some labs, 0.9 is the cut off while in others, it is different. Why is it so?
Thank you doctor,
If the result is 0.56 and the cut off is 0.9, does that mean the result is non-reactive? How should I interpret this result? If the result is 0.8, does it mean that the person is near the cut-off value hence at a higher risk? Or is any value below 0.9 considered out of risk?
Hello,

These tests are screening tests, and it is difficult to determine their accuracy. If you have some concerns, you may need to do a molecular test like PCR to confirm the results.
