Overview

The purpose of this test is to assess the susceptibility of Mycobacterium tuberculosis to 15 antitubercular drugs: Streptomycin, Isoniazid, Rifampicin, Ethambutol, Pyrazinamide, Clofazimine, Ethionamide, Capreomycin, Kanamycin, Amikacin, Ofloxacin, PAS, Cycloserine, Levofloxacin, and Moxifloxacin. It helps in identifying effective drugs for treatment, particularly in multidrug-resistant TB (MDR-TB), to tailor personalized therapy and prevent further resistance.
