A composite reference standard of either a positive Mycobacterium tuberculosis complex culture and/or GeneXpert(®) MTB/RIF (Xpert, Cepheid, Sunnyvale, CA, USA) results was used in the LAM-test diagnostic accuracy studies. We also determined if a 30 min α-mannosidase pre-treatment of urine using an enzyme that removes the mannose caps of LAM could improve the sensitivity of the LAM-test as we have shown in the laboratory settings [14] , and further correlated LAM-test results with TB incidence, mortality rates, and risk factors in our cohort of PLWH. ./cache/cord-306050-y8i8759c.txt ./txt/cord-306050-y8i8759c.txt
