Accuracy of 1st Generation Elisa
May 20, 2002
Would a Negative result via 1st Gen Elisa at 23 weeks be considered as accurate as a 3rd Generation Elisa. Thanks for all your help
Response from Mr. Kull
A 1st generation ELISA at 23 weeks after exposure is likely to be as accurate as a 3rd generation ELISA at three months. Early generation assays will detect antibodies to HIV in about 6 to 12 weeks following exposure; newer generation (3rd and 4th) can detect antibodies as early as three to four weeks. Also, newer generation tests are fine tuned to detect antibodies to all known subtypes of HIV. This is not as important for someone whose exposure is limited to the U.S., since subtypes that are commonly found in the U.S. would be detected by 1st generaiton.
Clearly, being antibody tested with newer generation assays is more desirable, and it is unlikely that you would be tested with 1st generation assays in the U.S, unless you use the Home Access testing system.
