Chromogranin A Blood Test

  • Item # LC140848

Chromogranin A (CGA) is a protein found in and released from neuroendocrine cells. The CGA test is used as a tumor marker and may be ordered in combination with or in place of serotonin to help aid in the diagnosis of carcinoid syndrome. Typical carcinoid symptoms include:

  • Flushing
  • Diarrhea
  • Abdominal pain
  • Wheezing
  • Valvular heart disease

Measurement of CGA is also useful as a tumor marker for adrenal tumors and small cell lung carcinoma. Elevated levels of CGA in patients with prostate cancer have been shown to correlate with poor prognosis.1

Instructions

Fasting is not required for this test. Take all medications as prescribed.
