BU Testing People with HIV for Tuberculosis Saves Lives

Tuberculosis (TB) is the leading cause of death for people with HIV. In sub-Saharan Africa, TB accounts for 40 percent of deaths among people with HIV, but nearly half of these TB cases go undiagnosed while the person is still alive.

Now, a new study co-authored by a Boston University School of Public Health (BUSPH) researcher shows that using urine tests for TB to screen all hospitalized patients with HIV would improve life expectancy and be cost-effective in Malawi and South Africa.

The study was published in The Lancet Global Health and could influence international guidelines on TB testing.

Thus, the availability of a urine-based test for TB that gives rapid results can be life-saving.”
