What is Immunohistochemistry -Chromogranin A?
This test detects Chromogranin A protein in a tissue sample using specific antibodies. Chromogranin A is a protein stored and released by neuroendocrine cells, which are found throughout the body. Its presence helps identify tumors originating from these specialized cells.
Why is this test important?
Chromogranin A is a crucial marker for diagnosing neuroendocrine tumors (NETs), including carcinoid tumors and pheochromocytomas. It helps confirm the neuroendocrine origin of a tumor, assess its differentiation, and monitor disease progression, guiding targeted therapies.
