Sputum for AFB (2nd Sample)

Overview:
The Sputum for AFB (Acid-Fast Bacilli) test using the second sample of sputum is used to detect Mycobacterium tuberculosis, the bacterium that causes tuberculosis (TB). This test is essential for diagnosing active tuberculosis, particularly when symptoms persist despite initial testing.

What it detects:
The test detects the presence of acid-fast bacilli (AFB) in the sputum, which indicates a potential tuberculosis infection. A positive result can confirm active TB, especially in individuals exhibiting symptoms like prolonged cough, fever, and night sweats.

Who should get it:
Individuals who are suspected of having tuberculosis or those who show symptoms such as a chronic cough, unexplained weight loss, fatigue, and night sweats may need this test. It is also used to monitor individuals at higher risk for TB, such as those with weakened immune systems or close contact with someone infected with TB.

Sample required:
Sputum sample (second sample of the day).
