Chromogranin A (CgA) Test for The Assessment of Neuro-Endocrine Tumors

The Chromogranin A (CgA) Test is a blood test used in medical settings to check for certain tumors, mainly in the digestive system and other organs. It helps doctors assess treatment response and prognosis in patients.

Here are the basic details of the Chromogranin A Test.

*Price range may vary as per location, lab type, and procedure of lab test.

Chromogranin A Test Means

Chromogranin A Test is a diagnostic blood test used to measure the levels of Chromogranin A in the bloodstream.

• It assesses neuroendocrine tumors, like those in the digestive system, by detecting elevated CgA levels.
• The test may help in monitoring treatment effectiveness and estimating prognosis for patients.
• CgA is produced by neuroendocrine cells and its levels can vary depending on the presence and status of these tumors.
• Interpretation of the results should consider the reference range and the patient's overall health situation.

Chromogranin A Test Purpose

The purpose of the Chromogranin A Test is to:

• Chromogranin A Test diagnoses neuroendocrine tumors like digestive and lung cancers.
• It monitors treatment response by assessing changes in CgA levels.
• CgA test helps estimate the prognosis or recovery chances for patients.
• Used for tumor recurrence detection after initial treatment.
• May aid in diagnosing neuroendocrine tumors in symptomatic individuals.
