DNA PCR tests, when/if 100% accurate?

Nov 24, 1998

With DNA PCR testing, when would you say that this test is 100% accurate and conclusive after an exposure to HIV? In your opinion, is DNA PCR testing at 28 days more accurate than HIV antibody/ELISA testing at the six month time frame? Are either test really 100% for sure? Once again, your response is greatly appreciated!

Response from Dr. Holodniy

DNA PCR testing today is close to 99.99% accurate. There is always the chance of a false negative. DNA PCR at 28 days, in my opinion (based on only limited published studies and personal observation), is equal to an ELISA at 6 months. MH
