TB DNA Detection by Realtime PCR, Reflex to Rifampicin Resistance by Ultra CBNAAT (if Positive), Sputum near me in Chennai

TB DNA Detection by Realtime PCR, Reflex to Rifampicin Resistance by Ultra CBNAAT (if Positive), Sputum test detects the presence of DNA from Mycobacterium tuberculosis (MTB complex) or Non-tuberculous bacteria (NTM/ MOTT) in your sputum sample by Real-time PCR. If the result is MTB positive, the reflex test of Rifampicin resistance by Ultra CBNAAT is performed to determine if the MTB strain is resistant to Rifampicin, a critical drug used in TB treatment. Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis bacteria. It primarily affects the lungs but can also impact other parts of the body. This test also helps assess the effectiveness of treatment for tuberculosis, detect drug-resistant (rifampicin-resistant) strains of tuberculosis, and identify other conditions that may mimic tuberculosis symptoms. Your doctor may recommend this test if you have symptoms suggestive of a tuberculosis infection, such as persistent cough, weight loss, and night sweats, or if you have a history of exposure to an affected person, were previously diagnosed with tuberculosis, have a suspected drug-resistant tuberculosis, or if you have a compromised immune system due to conditions like HIV/AIDS. Early diagnosis and treatment are crucial for successful management of tuberculosis.

Collect sputum in a sterile, leak-proof container with a screw-cap lid. Before collecting the sample, rinse your mouth with clean water. Take two to three deep breaths, then cough deeply to bring up sputum from the lungs. Ensure you collect at least 2 ml of thick, yellowish (muco purulent) sputum. Avoid collecting only saliva or nasal secretions. As per National Tuberculosis Elimination Programme (NTEP) guidelines, testing requires two sputum samples. This may include a spot and early morning sample collected on consecutive days, or two spot samples collected one hour apart, for accurate diagnosis of tuberculosis (TB).

Please note: This is an outsourced test. The sample for this test is collected by TATA 1MG and processed at a NABL accredited partnered lab.
