We also showed that the performance of the LAM-ELISA was not affected by 29 potentially interfering substances: nine anti-TB drugs, nine antipneumonia drugs, nine anti-HIV drugs, mucin, and serum, at a final concentration of 200 μg/mL (except for mucin, which was at 2,000 μg/mL) (Table B in S1 Appendix). Here, MUC5AC is linked to tuberculosis.
