sample requiredSample Required:

Sputum, bronchial washings, tissue specimens, or other bodily fluids.

test timeTest Time:

The test may take several weeks to provide results, as the samples need time to grow and be analyzed.

test normal rangeTest Normal Range:

The normal range does not apply to this test, as it is used to detect the presence of specific bacteria.

test procedureWhat is the Test?

The AFB (Acid-Fast Bacilli) Culture using the automated method is a laboratory test used to detect and identify Mycobacterium species, including Mycobacterium tuberculosis complex (which causes tuberculosis) and other non-tuberculous mycobacteria (NTM). The automated method uses specialized equipment to speed up the culturing process.

what is the testTest Procedure:

The sample (sputum, tissue, etc.) is collected and placed in a culture medium that supports the growth of mycobacteria. The automated system monitors and detects bacterial growth, and advanced software identifies the species present.

when to take the testWhen to Take the Test:

This test is ordered when there is a suspicion of tuberculosis or other mycobacterial infections. It’s used to diagnose active infections, monitor treatment progress, and determine antibiotic susceptibility.

who should take this testWho Should Take This Test:

Individuals with symptoms like persistent cough, fever, weight loss, night sweats, or who have been exposed to someone with tuberculosis may undergo this test.

precautions for exceptional casesPrecautions for Exceptional Cases:

Pregnant individuals and those with compromised immune systems should inform their healthcare provider before taking the test.



Q1: How long does it take to get the results of an AFB culture?

A: The results can take several weeks due to the slow growth of mycobacteria. Your healthcare provider will notify you when the results are available.

Q2: Can the AFB culture detect all types of tuberculosis?

A: The AFB culture can detect most types of tuberculosis, including drug-resistant strains. However, it may not always be able to identify all species of mycobacteria.

Q3: Can AFB culture results be false-negative?

A: Yes, there is a chance of false-negative results, especially if the bacteria are present in small amounts. Multiple samples may be required for accurate diagnosis.

Q4: Is the AFB culture test the only method to diagnose tuberculosis?

A: No, there are other tests, such as molecular tests and X-rays, that can aid in the diagnosis of tuberculosis.

Q5: What if my AFB culture is positive?

A: If the culture is positive, your healthcare provider will discuss the appropriate treatment plan, which may involve antibiotics and close monitoring.
