SensitivitySpecificityThe Balance of Sensitivity and SpecificityHow Sensitive and Specific Are HIV Tests?The sensitivity of an HIV test is defined as the proportion of people with HIV who will receive a positive result. In other words, a highly sensitive test is one that correctly identifies people living with HIV who take the test. 1. A test that is 100% sensitive would identify allHIV-positive people who take the test. 2. Many HIV tests have 99% sensitivity. A test with this sensitivity would identify 99% of HIV-positive people, but would miss 1% of them. They would get false negative results. 3.

Immunoglobulin M, or IgM for short, is a basic antibody that is produced by B cells. IgM is by far the physically largest antibody in the human circulatory system. It is the first antibody to appear in response to initial exposure to an antigen. The spleen, where plasmablasts responsible for antibody production reside, is the major site of specific IgM production.
