Response from Dr. Frascino

Hello,

I have not seen any convincing evidence that brushing teeth, drinking coffee or smoking affects OraQuick Advance HIV-1/2 test results.

The report from Seattle was concerning. The FDA has asked OraSure, the company that manufactures OraQuick tests, to investigate the Seattle findings. (See below.)

In your particular case, I see no cause for concern. You have had three negative OraQuick tests. The chance of three false-negatives on the same individual would be beyond remote. If you are concerned, get an ELISA test (blood test). The result will undoubtedly be negative, but if it puts your (unwarranted) worries permanently to rest, it may be worth the time, effort, money and blood.

One final piece of advice: stop smoking! If you don't, cigarettes will kill you in a very painful and undignified fashion.

Be well. Stay well.

Dr. Bob
