Acid-Fast Bacilli (AFB) Test

The Acid-Fast Bacilli (AFB) test is used to detect the presence of acid-fast bacilli, which are a group of bacteria that includes Mycobacterium tuberculosis, the bacteria that causes tuberculosis (TB). The test is typically used to diagnose TB in the lungs, but can also be used to detect TB in other parts of the body, such as the lymph nodes or the urinary tract.

Pre-test preparation: No special preparation is needed before the test.

Testing method: The test is typically performed on a sample of sputum, which is coughed up from the lungs. The sample is collected in a sterile container, and then sent to a laboratory for testing. The laboratory will then use a staining technique, called Ziehl-Neelsen or Kinyoun staining, to identify the presence of acid-fast bacilli in the sample.

Common symptoms for prescribing this test: Symptoms of TB include a persistent cough, chest pain, weight loss, fever, night sweats, and fatigue.

Diagnosis: A positive AFB test result indicates the presence of acid-fast bacilli, which is strongly suggestive of TB. However, a positive test result does not confirm the diagnosis of TB, as other conditions can also cause a positive test result. Therefore, a positive AFB test result should be followed up with other tests, such as a chest x-ray and a culture of the bacteria, to confirm the diagnosis of TB.

Reference range: Not applicable

Normal values: A negative AFB test result indicates that no acid-fast bacilli were found in the sample, and that TB is unlikely to be the cause of the symptoms.
