Antibiogram – MTB (Rifabutin)

Antibiogram test or Antimicrobial Susceptibility testing is performed to measure the susceptibility of microbes to certain antibiotics. Antibiogram MTb (Rifabutin) test checks for the sensitivity or resistance of MTB to Rifabutin drug. Rifabutin is a first-line antibiotic used to treat tuberculosis and prevent and treat Mycobacterium avium complex. It is typically only used in those who are intolerant to rifampin such as people with HIV/AIDS on antiretrovirals. For active tuberculosis, it is used with other antimycobacterial drugs. For latent tuberculosis, it may be used by itself when the exposure is with drug-resistant TB.
