This test is for use as the antibody differentiation test in the specific multi-test algorithm. If results are negative or indeterminate, this test does NOT reflex to a nucleic acid test.

A multi-test algorithm is recommended by the Centers for Disease Control and Prevention (CDC) and the Clinical Laboratory Standards Institute (CLSI) for the diagnosis of HIV (refer to https://www.arupconsult.com/Topics/HIV.html).
