Which laboratory test identifies tissue obtained from a biopsy?

• A. Edema
• B. Punch biopsy
• C. Tissue pathology
• D. Aerobic/anaerobic culture

Answer: (C)

Tissue pathology is the laboratory analysis that identifies tissue obtained from a biopsy. In this process, the biopsy specimen is fixed, processed, and sliced into thin sections that are stained so a pathologist can examine them under a microscope. By evaluating cell appearance, organization, and tissue architecture, the pathologist determines what kind of tissue it is and whether disease is present—such as cancer, inflammation, or infection. The resulting pathology report provides the diagnosis and may describe tumor type, grade, and surgical margins if relevant. Edema describes swelling and is not a lab analysis of tissue. A punch biopsy is the method used to obtain tissue, not the test that analyzes it. Aerobic/anaerobic culture checks for microbial growth, not tissue structure.
