HIV Tests
ELISA test -> Western Blot
ELISA – 18-45 days – Highly sensitive and no false (-)negative. Negative is Negative. No HIV. No more testing. However, ELISA sometimes generates false (+)positive –> then (Automatically) Western Blot
Western Blotが(+)/Positive. One of the reasons of the positive result is “maybe it was too soon” –> Repeat test in 3 months. OR PCR test for quicker result.
RNA Testing is available as early as 10 days — test for virus itself.
