BLOCK FOR AFB

BLOCK FOR AFB

Block for AFB (Acid-Fast Bacilli) is a laboratory examination performed on a tissue block to look for acid-fast bacteria, particularly Mycobacterium tuberculosis. It may be recommended when tuberculosis is suspected in a tissue sample or when a stored biopsy specimen requires further evaluation. The test can help provide evidence of TB infection in the examined tissue. Results should be interpreted along with histopathology, symptoms, and other TB investigations.
