Chromogranin A Testing. Test code (s) 31912, 31911. Question 1. What method does Quest Diagnostics use for measurement of chromogranin A? Question 2. How do results from the LC/MS/MS assay correlate with those from the ELISA-based chromogranin A test? Chromogranin A (ChgA) is an acidic glycoprotein found in large dense-core vesicles of the regulated secretory pathway (1, 2).A number of other vesicular proteins sharing physiochemical properties with ChgA have been identified, giving rise to a family of “granins,” which includes chromogranin B (ChgB), secretogranin II, secretogranin III, …

Chromogranin A (CgA) is a 46-kDa glycoprotein, member of the granin family, exists within all type of neurons, normal neuroendocrine cells and is expressed in NET cells [7, 8]. Over the past 2 decades, many studies reported and confirmed that CgA was a reliable diagnostic biomarker for NETs including gastroentero-pancreatic NETs (GEP-NET) [ 1 ...

CgA is a protein found in and released from neuroendocrine cells. Neuroendocrine cells, and the endocrine system glands that they are found in, can give rise to a variety of tumours, both benign and malignant. They include carcinoid tumours, phaeochromocytomas, insulinomas, small cell lung cancers, neuroblastomas, and other neuroendocrine tumours.

The Chromogranin A [CgA] blood test is ordered when there is a suspicion of a carcinoid syndrome present within a patient. It may also be routinely ordered to monitor the treatment of such a syndrome. In its early stages, carcinoid syndrome can be very difficult to detect. Many of the signs and symptoms of it are similar to other health issues ...

Evaluate for ovarian estrogen producing tumor in the premenarcheal and postmenopausal female; evaluate estrogen excess in males. Estrogen analysis may be helpful in establishing time of ovulation and optimal time for conception. Serial samples must be collected over several days to evaluate baseline and peak total estrogen levels.

Chromogranin A is also elevated in 80% to 90% of patients with symptomatic foregut and midgut tumors. -Urine serotonin is in most circumstances the least likely marker to be elevated. The exception is tumors (usually foregut tumors) that produce predominately 5-HTP, rather than serotonin, and also secrete little, if any, chromogranin A. Labcorp test details for Chromogranin A.
