IHC: Chromogranin Test Cost & Procedure

All neuroendocrine neoplasms can be diagnosed using chromogranin-A (CGA).

What is the purpose of this examination?

To measure Chromogranin levels, the IHC Chromogranin test is used. It aids in confirming neuroendocrine tumors and is tested on a biopsy sample. The body's organs contain neuroendocrine cells, which function as nerve and hormone cells. Numerous tumor types can develop from these cells and the glands that make up the endocrine system. In addition to neuroendocrine tumors, the test may also be used to detect other malignancies.

The test is additionally applied when treating a neuroendocrine tumor. If you experience symptoms similar to cancer, such as nausea, vomiting, rapid heartbeat, wheezing, coughing, and the like, your doctor may suggest you undergo the test.

Preparation for this test

You don't have to get ready specifically for the test. You only need to ensure you've obtained all the details from your doctor and are familiar with the procedure and the medication. Your doctor would also like to know what medications or dietary supplements you take because some drugs can impact the test. Your doctor would suggest the best course of action based on your circumstances.

Benefits

Chromogranin levels are typically relatively low. You generally are at risk of developing a neuroendocrine tumor if the test shows that your Chromogranin levels are within the normal range. Your Chromogranin level and test findings could, nevertheless, indicate cancer risk. Chromogranin levels indicate the presence of a tumor when they are high.

However, the report does not mean the type of cancer or its location. The tumor and its condition must be discovered, biopsied, and analyzed by a pathologist to learn its precise characteristics.

Immunohistochemistry is used in the test's procedure

This technique uses a uniqudesignre that helps locate tumors by particular imaging antigens in tissue cells.
