Description
NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
Sputum, bronchial washings, tissue specimens, or other bodily fluids.
Test Time:
The test may take several weeks to provide results, as the samples need time to grow and be analyzed.
Test Normal Range:
The normal range does not apply to this test, as it is used to detect the presence of specific bacteria.
What is the Test?
The AFB (Acid-Fast Bacilli) Culture using the conventional method is a laboratory test that helps detect and identify Mycobacterium species, including Mycobacterium tuberculosis complex (which causes tuberculosis) and other non-tuberculous mycobacteria (NTM). The conventional method involves manual culturing and observation of bacterial growth.
Test Procedure:
The sample (sputum, tissue, etc.) is collected and placed in a culture medium that supports the growth of mycobacteria. The culture is incubated under controlled conditions, and trained laboratory professionals visually monitor the growth over a period of weeks.
When 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 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 Cases:
Pregnant individuals and those with compromised immune systems should inform their healthcare provider before taking the test.
