- For those who fear they may be infected with HIV-1, the virus
- that causes AIDS, the wait between taking a blood test and
- getting the results can be agonizing. The tests must be
- processed in a laboratory, and it can take days for a patient
- to find out if the deadly virus is spreading through his or her
- body. Last week, though, the FDA approved a new HIV test that
- gives results in just 10 minutes. It can be run in a doctor's
- office by someone with minimal training. All it takes is two
- test tubes, some chemicals, a medicine dropper and a blood
- sample (all but the last come packaged in a kit). If the
- solution turns blue, the blood has antibodies to HIV and thus
- has the virus as well. The test is more than 99% accurate, but
- for absolute certainty, a positive result has to be confirmed
- by a more elaborate lab test. That's also the case with
- conventional HIV exams -- as is the advice to be retested in six
- months: it can take that long after infection for antibodies to
- appear.
