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.
