About this test

What is the Aspirated Fluid for AFB Test?

Aspirated Fluid for AFB is a laboratory investigation performed on a fluid sample collected through aspiration. It is used to check for acid-fast bacilli, a group of bacteria that includes Mycobacterium tuberculosis, which causes tuberculosis. The investigation may help evaluate suspected tuberculosis involving body fluids.

Why is Aspirated Fluid for AFB Testing Performed?

A doctor may recommend this test when tuberculosis or another mycobacterial infection is suspected in a particular body cavity or fluid collection. The result can provide useful information as part of the diagnostic evaluation.

What Can the Test Help Detect?

  • Acid-fast bacilli in the submitted fluid sample
  • Possible mycobacterial infection
  • Findings that may support the evaluation of extrapulmonary tuberculosis
  • Evidence requiring further microbiological investigation

How is the Test Performed?

Aspirated fluid is collected by a qualified healthcare professional using an appropriate aspiration procedure. The specimen is transported to the laboratory for examination. Depending on the requested investigation, testing may involve AFB staining and microscopy or additional microbiological methods.

Preparation Before the Test

  • Follow the instructions provided by your treating doctor.
  • Inform the healthcare team about current medications and medical history.
  • Share details of previous tuberculosis investigations, if available.

Understanding AFB Test Results
