WHAT IS IT?

To measure Chromogranin levels, the IHC Chromogranin test is used. It aids in the confirmation of neuroendocrine tumors and is tested on a biopsy sample. The body's organs include neuroendocrine cells, which function as both nerve and hormone cells. These cells, in conjunction with endocrine system glands, have the ability to produce a variety of tumor types. In addition to neuroendocrine tumors, the test may also be used to detect other tumors. Additionally, a neuroendocrine tumor is treated with this test both during and thereafter. If you exhibit symptoms similar to those of a tumor, such as vomiting, nausea, a fast heartbeat, wheezing, coughing, and the emergence of a deep red color on your face and neck, your doctor may suggest you to undergo the test.

WHY?

Chromogranin levels in blood are typically low. You are often not at danger of a neuroendocrine tumor if the test results for Chromogranin indicate that it is within the normal range. However, there's a potential that your Chromogranin level and findings don't accurately represent the presence of a tumor. The existence of a tumor is indicated if the level of chromogranin is high, however the report does not indicate the tumor's location or kind. It must be found, biopsied, and analyzed by a pathologist in order to determine the precise characteristics of the tumor and its status.

PRECAUTIONS

There is no need for you to focus on exam preparation. All you need to do is make sure you have all the necessary information from your doctor and are fully informed about the procedure and drugs. In addition, since some drugs might alter the test, your doctor would also like to know what vitamins or medications you take. Your doctor will advise you on the best course of action for you based on your situation.
