TB Sensitivity (Streptomycin) is a test to ascertain whether a human body infected with TB will respond to Streptomycin. An antibiotic, Streptomycin is used to treat a number of bacterial infections including Tuberculosis (TB). A sensitivity test, also known as susceptibility test, is performed to determine the effectiveness of an antibiotic drug in stopping the growth of the bacteria causing the infection. Results of sensitivity testing are usually reported as Susceptible, Intermediate, or Resistant after which the practitioner decides whether to prescribe the drug or not. Samples may be taken from blood, urine or sputum (spit).
