Description
Why It’s Done:
This test is ordered to:
• Diagnose tumors or masses, whether benign or malignant
• Evaluate abnormal growths, ulcers, or persistent symptoms
• Investigate findings from imaging studies (CT, MRI, ultrasound)
• Detect infections, inflammatory conditions, or autoimmune diseases
• Assist in treatment planning, surgical decisions, or disease monitoring
It is especially useful when a small biopsy is insufficient for diagnosis but a full surgical resection is not yet warranted.
Preparation:
Preparation depends on how the specimen is obtained:
• Fasting may be required if sedation or general anesthesia will be used.
• Inform your doctor if you:
o Are taking blood thinners (e.g., aspirin, warfarin)
o Have bleeding disorders
o Have allergies to anesthesia or antiseptics
o Are pregnant or on medications
• Follow all pre-procedure instructions, which may include temporarily stopping medications or arranging for someone to accompany you.
After collection, the tissue is preserved in formalin, processed, and examined. The pathology report is typically available in 3 to 7 days, depending on the complexity.
