AFB Susc. Amikacin

What is the purpose of the AFB susceptibility to amikacin test?

This test determines the susceptibility of acid-fast bacilli (AFB), such as Mycobacterium tuberculosis, to amikacin, an aminoglycoside antibiotic. It guides effective treatment for tuberculosis (TB) and other mycobacterial infections.


When is the AFB susceptibility to amikacin test recommended?

It is recommended when patients are diagnosed with drug-resistant tuberculosis or atypical mycobacterial infections, to assess the effectiveness of amikacin as part of the treatment regimen.


How is the AFB susceptibility to amikacin test conducted?

A cultured sample from sputum or other body fluids is tested against amikacin to determine the minimum inhibitory concentration (MIC) and assess susceptibility.


What do the test results indicate?

Susceptibility indicates that the organism can be effectively treated with amikacin, while resistance suggests the need for alternative antibiotics.
