AFB-DNA (TB-PCR) Detection – Pus / Abscess / Aspirate

This test is a diagnostic test that uses real-time PCR to detect the presence of AFB-DNA, which is specific to Mycobacterium tuberculosis (MTB), the bacteria causing TB, or Non-tuberculous bacteria (NTM or MOTT) in pus, abscess, or aspirate samples. 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, an important drug used in TB treatment.

• Diagnose and confirm infections caused by Mycobacterium tuberculosis or Non-tuberculosis bacteria.
• Differentiate between TB and other infections.
• Guide appropriate treatment decisions.
• Identify cases of rifampicin resistance.

This test is recommended for individuals with suspected Mycobacterium tuberculosis infection or non-tuberculosis bacterial infection based on symptoms such as persistent cough, fever, weight loss, night sweats, or enlarged lymph nodes. It is especially helpful for patients with compromised immune systems, close contacts of TB patients, or those suspected of having drug-resistant TB.

If the test results are positive for Mycobacterium tuberculosis or Non-tuberculosis bacteria, it indicates the presence of an active infection. If rifampicin resistance is detected, it suggests that the bacteria causing the infection may be resistant to this important anti-TB medication.

For this test, a sample of pus, abscess, or aspirate is collected in a sterile container. The sample is sent to the laboratory for testing. The test is painless and only requires providing a sample.

There are no specific preparations required for this test. Please reach out to your healthcare provider for any specific requirements.

• Chest X-ray: To evaluate lung involvement in TB cases.
•  Sputum Culture: To isolate and identify the bacteria causing the infection.
•  Drug Susceptibility Testing: To determine the effectiveness of specific antibiotics against the identified bacteria.

TB-PCR, MTB PCR

Tuberculosis (TB) is an infectious disease caused by the bacterium Mycobacterium tuberculosis. It primarily affects the lungs but can also affect other parts of the body. TB is a major global health concern and can be life-threatening if left untreated.
