he Fujifilm SILVAMP TB LAM test, or FujiLAM, is the first of a new generation of rapid diagnostic tests for the identification of TB in people co-infected with HIV. Working in a similar way to a pregnancy test, FujiLAM detects low concentrations of lipoarabinomannan (LAM) in the urine of people with TB and HIV co-infection. Urine samples are easy to collect from people of all ages, which is especially relevant for those with HIV who may often face difficulties in producing sputum (the usual sample needed for TB tests). FujiLAM has shown promise following an encouraging diagnostic accuracy evaluation using biobanked (frozen) urine samples from hospitalized patients with HIV, and these findings were presented in a study published in the journal Lancet Infectious Diseases. The study found that the test is substantially (28%) more effective at identifying TB in people who are HIV positive than the only existing alternative urine test. Rapid and accurate diagnosis of TB is critical to enable patients to start treatment on time, reduce deaths due to TB, and prevent further transmission of the disease. The test is now being evaluated in large studies in more than ten countries, which will help to generate the data needed for evaluation by the World Health Organization (WHO). |
