About this test

The AFB culture by BACTEC MGIT method is an automated liquid culture system that detects Mycobacterium tuberculosis and other mycobacteria. It is faster and more sensitive than traditional solid culture, with positive results often in 1–2 weeks. Negative results are reported after 6 weeks.

A positive culture confirms active TB or non-tuberculous mycobacterial (NTM) infection, even when smear tests are negative. It can be done on sputum, BAL, body fluids, tissue, CSF, or urine.

It also enables drug sensitivity testing and helps monitor treatment response.

Questions about this test

When should I get the AFB Culture By Bactec (MGIT) Method test?

You should get an AFB culture by MGIT if you have a cough lasting more than 2 weeks, coughing up blood, fever, night sweats, or weight loss, especially when sputum smear is negative but TB is suspected. It is also recommended for extrapulmonary TB, suspected NTM infection, drug resistance testing, and monitoring TB treatment.

How should I prepare for the AFB Culture By Bactec (MGIT) Method test?

For an AFB culture by MGIT, a sputum sample is most common. Collect an early morning sample by coughing deeply, after rinsing your mouth with plain water. Avoid toothpaste, mouthwash, or food beforehand. Ideally, give the sample before starting TB medicines. For other samples, such as fluids or tissue, follow your doctor’s instructions.

Do I require fasting for the AFB Culture By Bactec (MGIT) Method test?

No, fasting is not required for an AFB culture by MGIT. However, if a sputum sample is used, it is best collected early in the morning before eating or drinking, after rinsing your mouth with plain water. Avoid toothpaste or mouthwash before collection for accurate results.
