The LAM assay has substantially superior sensitivity to sputum microscopy as a routine diagnostic TB screening test among patients with CD4 cell counts less than 100 cells/microliter. In one half of such patients, this assay could reduce the mean time to diagnosis by approximately 3 weeks. Furthermore, detectable urinary LAM may predict the development of TB immune reconstitution disease.
Lawn et al. (2009) studied this question.
