"FRIDAY, Aug. 27 (HealthDay News) — The brain can be a convenient hiding place for HIV, the virus that causes AIDS.
That’s the finding of Swedish researchers who analyzed samples from about 70 HIV-infected patients who’d been taking anti-HIV drugs. The tests showed that about 10 percent of the patients — a larger proportion than expected — had traces of HIV in their spinal fluid but not in their blood.

Good thing that HIV tests are looking for antibodies, not HIV virus then, don't you think? Care to post any studies about antibody tests? This is clearly viral load results, and not the same thing. Antibodies don't hide in your brain.
From your own stupid link:
University of Maryland researcher Niel Constantine explains that "screening tests possess a high degree of sensitivity, whereas confirmatory assays have a high specificity. Tests with high sensitivity produce few false-negative results, whereas tests with high specificity produce few false-positive results." Because the screening tests can produce false positives, a second screening test is typically run on the same sample – in duplicate – with the confirmatory tests only run on samples that are repeatedly positive ("reactive" in lab parlance).
The combination of the two types of tests produces results that are "highly accurate," Constantine notes, but technical errors are possible, and biological factors can occasionally produce problems.
Thanks for playing
