Muscle madness.

ABSTRACT

AIDS The Bio-electrical Impedance Analysis (BIA) test is being used to follow wasting syndrome in patients with HIV infection because of its ability to determine how much muscle and fat a person has in their body. Because muscle mass is essential to supporting the immune system, suppressing viral replication, and avoiding opportunistic infections, it is important to track any changes. The test is painless and involves an electrode attached to one foot and a hand whereby an electrical current is passed through the body and its speed is measured. The faster the passage, the more muscle is present. Results of the test include a fluid assessment, body cell mass, fat mass, and a cellular health measure.^ieng
