Frequently Asked Questions
What does the MTB mRNA PCR test detect?
This test detects the genetic material (mRNA) of Mycobacterium tuberculosis in sputum, fluid, tissue, or pus samples, enabling rapid and accurate diagnosis of active TB infection.
Is fasting required for this test?
No, fasting is not required. This is a molecular test performed on sputum, fluid, tissue, or pus samples, not a blood metabolic test.
How long does it take to get results?
Results are typically available within 24–48 hours depending on the sample type and processing schedule at our NABL-accredited molecular biology laboratory.
What sample types are accepted for this test?
Sputum, pleural fluid, ascitic fluid, CSF, tissue biopsies, and pus samples are accepted. Adequate sample volume (minimum 3 mL) is essential for accurate molecular detection.
Can this test distinguish between active and latent TB?
MTB mRNA PCR detects actively transcribing (viable) Mycobacterium tuberculosis organisms, making it more specific for active disease compared to DNA-based tests that may detect dead bacteria.
What should I do if my test result is positive?
A positive result indicates the presence of Mycobacterium tuberculosis and requires immediate consultation with a physician for initiation of anti-tubercular therapy. Contact your doctor for further evaluation and treatment planning.
