Although HIV
clinics in San Francisco, Los Angeles, and New York City
have reported an unacceptable number of false-positive
results from the OraQuick oral rapid HIV antibody
test, three Atlanta agencies providing testing say
they haven't experienced similar problems, the
Southern Voice reports.
"We've certainly
not had any major problems with the oral test and have
had minimal false positives," Michael Banner, director of
prevention services at Our Common Welfare, told the
Voice. "But we've decided to go back to the
finger-prick test until we get a definitive answer from
OraSure."
The OraQuick
Advance rapid HIV test can use oral fluids collected by a
swab, blood from a needle-stick, or blood drawn by a syringe
to screen for HIV antibodies and produce results in
about 20 minutes. The reports of high numbers of
false-positive results are linked only with the oral
tests and not those that examine blood, health officials
say.
Officials at
Atlanta AIDS groups the AIDS Survival Project and AID
Atlanta also report no abnormally high numbers of
false-positive results. At AID Atlanta, only about one
false-positive result occurs out of every 800 to 900
tests given, officials say.
OraSure
Technologies, the Food and Drug Administration, and the
Centers for Disease Control and Prevention are all
investigating the high numbers of false-positive
results seen in clinics in New York and
California--and why the problem hasn't
cropped up in other major U.S. cities. (Advocate.com)
