Oral Fluid HIV Tests Give False-Positive Results

According to the report, the reason for the episodic increase in false-positive oral-fluid tests has not yet been determined. Currently, the New York City Department of Health and Mental Hygiene (NY, USA) suspended the use of oral fluid testing in its sexually transmitted infection (STI) clinics, and finger-stick whole-blood testing is the only rapid HIV test being used.

The "findings underscore the importance of confirming all reactive HIV tests, both from oral fluid and whole-blood specimens,” according to MMWR. They further indicate that the health department's "strategy of following-up reactive oral fluid test results with an immediate finger-stick whole-blood test reduced the number of apparent false-positive oral fluid test results and might be a useful strategy in other settings and locations.” The report also noted that, "The U.S. Center of Disease Control and Prevention [CDC; Atlanta, GA, USA] continues to encourage the use of rapid HIV tests because they increase the number of persons who are tested and who receive their test results.”
