About this test
The TB PCR test detects genetic material of tuberculosis bacteria to provide rapid and accurate diagnosis of TB infection.

The TB – PCR (Polymerase Chain Reaction) test is a molecular diagnostic test used to detect the DNA of Mycobacterium tuberculosis, the bacterium that causes tuberculosis (TB).

This test is highly sensitive and specific, allowing early detection of TB even when bacterial load is low. It can be performed on various samples such as sputum, pus, body fluids, or tissue, depending on the suspected site of infection.

TB PCR provides faster results compared to traditional culture methods and is useful in diagnosing both pulmonary and extrapulmonary tuberculosis. It may also help in detecting drug resistance when combined with advanced techniques.

Test Recommended For

  • Individuals with suspected tuberculosis
  • Patients with persistent cough, fever, or weight loss
  • People with suspected extrapulmonary TB
  • Individuals with inconclusive conventional test results
  • Patients advised for molecular TB testing
