WHO recommends lateral flow LAM to assist and expedite the diagnosis of TB in two specific population groups: in HIV-positive, adult in-patients with signs and symptoms of TB (pulmonary and/or extrapulmonary) and a CD4 cell count ≤100 cells/mm3, and people living with HIV who are seriously ill and in respiratory distress (regardless of CD4 count or if the CD4 count is unknown) [6]. Here, CD4 is linked to tuberculosis.
