Direct TMKmt Ag and specific IgG Ab Detection EIA were conducted on broadly consented, stored serum ([N=281 for Ag detection] vs. [N=214 for Ab detection]) samples stratified as either HIV +ve (139 vs. 122) or HIV −ve (47 vs. 37 for Ag and Ab detection respectively) ATB relative to LTBI (83 vs. 47) and No TB (10 vs. 8). Here, RENBP is linked to tuberculosis.
