Hi doctor,

Is there any MDR-TB test for formalin based tissue? I had biopsy, but they dipped it in formalin. Now I asked for another biopsy for GeneXpert test. What to do?

Hi,

Welcome to icliniq.com.

  • The GeneXpert test is a molecular test which detects the DNA in TB bacteria (tuberculosis).
  • Formalin treated tissue might have TB bacteria which are dead and do not have viable DNA material. Therefore, repeat biopsy has been suggested.
