AFB (TB) – Antibiogram for MTb Complex – Isoniazid Drug by MGIT – Pure Growth of MTB Complex

This test determines the drug susceptibility of the MTb complex to isoniazid.

• To determine if the bacteria causing TB are resistant or sensitive to isoniazid. • To guide doctors in prescribing appropriate treatment plans for patients with TB. • To minimise the risk of drug resistance by selecting effective medications. • To monitor and evaluate treatment effectiveness and make necessary adjustments.

This test may be recommended if you • Have been diagnosed with TB and need to determine drug susceptibility. • Require a change in your TB medication due to treatment failure or drug resistance. • Are at high risk of developing drug-resistant TB. • Have been exposed to someone with drug-resistant TB. • Have recurrent or persistent symptoms of TB despite receiving treatment.

Abnormal results suggest that the bacteria causing TB may be resistant to isoniazid.

Please reach out to your healthcare provider for any specific requirements.

Other tests that may be ordered alongside this test include: • AFB smear microscopy: This test helps identify the presence of acid-fast bacilli (AFB) in sputum or other specimens. • Xpert MTB/RIF assay: This molecular test detects the presence of TB bacteria and checks for rifampicin resistance.

Tuberculosis (TB) is an infectious disease caused by the bacteria Mycobacterium tuberculosis. It primarily affects the lungs but can also affect other parts of the body. TB spreads through the air when an infected person coughs or sneezes. Common symptoms include persistent cough, weight loss, fatigue, and night sweats. Early diagnosis and appropriate treatment are crucial for managing TB effectively.
