Truenat® MTB-INH is a chip-based Real-Time PCR test developed to detect Isoniazid (INH) resistance in Mycobacterium tuberculosis (MTB) strains. It is applied to patients diagnosed with Mycobacterium tuberculosis and helps in the diagnosis of multidrug-resistant tuberculosis (MDR-TB). This test rapidly and accurately identifies resistant strains by detecting key mutations (SNPs) in the MTB genome that lead to Isoniazid resistance.
