Hi Very Worried Person,

Negative ELISA tests at five months are considered true negative tests. False negatives are generally not a problem with ELISA screening. I do not feel another test is warranted or necessary, medically speaking. However, if despite my reassurance you remain a "very worried person," you certainly could retest at the six-month mark. The results will undoubtedly be negative. If this, however, puts your (unwarranted) worries permanently to rest (where they belong), it may be worth the effort psychologically.

Thank you for your donation to The Robert James Frascino AIDS Foundation (www.concertedeffort.org). It's warmly appreciated. In return I'm sending you my good-luck karma that you are now and will always be HIV free.

Good luck.

Dr. Bob
