Lateral flow urine lipoarabinomannan assay for detecting active tuberculosis in people living with HIV

Post Date:

2019-10-21

Publication:

Cochrane Database of Systematic Reviews

Why is improving the diagnosis of tuberculosis important? Tuberculosis causes more deaths in people living with HIV than any other disease. The lateral flow urine lipoarabinomannan assay (LF-LAM, Alere Determine™ TB LAM Ag assay) is a World Health Organization-recommended rapid test to assist in detection of active tuberculosis in HIV-positive people with severe HIV disease. Rapid and early tuberculosis diagnosis may allow for prompt treatment and alleviate severe illness and death. An incorrect tuberculosis diagnosis may result in anxiety and unnecessary treatment.
