Gastric Fluid for AFB Price in Bangladesh

What is Gastric Fluid for AFB?

Testing gastric fluid for Acid-Fast Bacilli (AFB) is used to diagnose tuberculosis (TB), especially in cases of pulmonary TB when sputum samples are unavailable or inconclusive. Gastric fluid is aspirated early in the morning after fasting, using a nasogastric tube.

The sample is processed with microscopy (Ziehl-Neelsen stain) or cultured for Mycobacterium tuberculosis. Preparation includes fasting overnight to ensure concentrated fluid.

Risks involve mild discomfort, nasal irritation, or minor bleeding. Positive AFB results indicate TB, but culture is more sensitive and confirms the diagnosis.

Negative results may occur due to low bacterial load, so repeated tests or complementary diagnostics are often needed.

What to expect & how to prepare

Gastric Fluid for AFB is performed at a diagnostic centre or hospital lab. A trained technician collects the required sample (commonly a blood draw, urine sample, swab or an imaging scan, depending on the test) and sends it to the lab for analysis. Most routine tests take only a few minutes to sample, with reports typically ready the same day or within 24–48 hours.

• Fasting: some tests require 8–12 hours of fasting (water is usually allowed). Ask the centre when you book.
• Medication: tell the lab about any medicines or supplements you take, as some can affect results.
• Timing: certain hormone and biochemistry tests are best done in the morning — confirm the recommended time.
• Report: always have a registered doctor interpret your Gastric Fluid for AFB result rather than self-diagnosing.
