Description
Serum, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
Ascitic fluid obtained through a diagnostic procedure called paracentesis.
Test Time:
Results are usually available within a few hours to a day after sample collection.
Test Normal Range:
The normal range does not apply to this test. The presence of acid-fast bacilli (AFB) in the ascitic fluid suggests a potential tuberculosis infection.
What is the Test?
The AFB Stain, Ascitic Fluid test is a microscopic examination of ascitic fluid to detect the presence of acid-fast bacilli (AFB). AFB are characteristic of mycobacteria, including Mycobacterium tuberculosis, the causative agent of tuberculosis.
Test Procedure:
A sample of ascitic fluid is collected through paracentesis and then processed for staining using the Ziehl-Neelsen stain. The stained slide is examined under a microscope for the presence of red-stained AFB, which appear against a blue background.
When to Take the Test:
This test is ordered when there is a suspicion of tuberculosis infection involving the abdominal cavity (peritoneum), which can cause ascites.
Who Should Take This Test:
Individuals who present with ascites, especially when tuberculosis infection is suspected, 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.
FAQs:
Q1: What is ascites?
A: Ascites is the accumulation of fluid in the abdominal cavity, often due to conditions like liver disease or infection.
Q2: Is ascitic fluid collection painful?
A: The procedure may cause some discomfort, but it is usually not very painful. Local anesthesia may be used to numb the area.
Q3: What if AFB are found in the ascitic fluid?
A: The presence of AFB suggests a potential tuberculosis infection. Further testing, such as culture and drug sensitivity testing, may be needed for confirmation and appropriate treatment.
Q4: Can I eat before the ascitic fluid collection?
A: You may need to fast for a few hours before the procedure. Your healthcare provider will provide specific instructions.
Q5: Is ascites related to cancer?
A: Ascites can be related to various underlying conditions, including cancer. It’s important to determine the cause through medical evaluation and testing.
