What Is Considered A High Chromogranin A Level - Changes in cga levels normalization or ≥30% decrease suggested that patients had tumor response. Web what does it mean if your chromogranin a (cga) result is too high? Web last modified on mar 18, 2022. What does the result mean? Web wheezing, coughing, difficulty breathing. Web serum cga levels were much higher in patients who classified as neuroendocrine carcinoma, mixed adenoendocrine carcinoma ( p = 0.035) and who were on stage iv ( p = 0.041). Web from what my gi doctor has told me that the chromogranin a level can be high if you take proton pump inhibitors (meds like prilosec, etc.). An increased chromogranin a level in a person with symptoms may indicate the presence of a tumor, but it is not specific for the type of tumor or its location. ≤225 ng/ml [ 1] however, the reference ranges for serum chromogranin a vary widely with the techniques used. Cga, serum cga, cga blood test, chromogranin a blood test.
The level of chromogranin a in the blood is normally low. Specimen requirement is a red top tube of blood. Chromogranin a (cga) is a protein released by neuroendocrine cells. Web what does it mean if your chromogranin a (cga) result is too high? Chromogranin a is a useful diagnostic biomarker for neuroendocrine tumors such as carcinoid tumors, pheochromocytoma and neuroblastoma. Web cga is elevated in most patients (approximately 90%) with symptomatic or advanced carcinoids (carcinoid syndrome), usually to levels several times the upper limit of the reference interval. Also, liver, kidney, or heart problems can also raise the cga levels. A person with no signs or symptoms and a normal level of cga is unlikely to have a neuroendocrine tumour. Web serum cga levels were much higher in patients who classified as neuroendocrine carcinoma, mixed adenoendocrine carcinoma ( p = 0.035) and who were on stage iv ( p = 0.041). Cga, serum cga, cga blood test, chromogranin a blood test. What does the result mean? Changes in cga levels normalization or ≥30% decrease suggested that patients had tumor response. ≤225 ng/ml [ 1] however, the reference ranges for serum chromogranin a vary widely with the techniques used. Web last modified on mar 18, 2022. A hook effect may occur at extremely high chromogranin levels resulting in falsely decreased values. This test may be ordered periodically to help evaluate treatment effectiveness and monitor for tumour recurrence. Web from what my gi doctor has told me that the chromogranin a level can be high if you take proton pump inhibitors (meds like prilosec, etc.). An increased chromogranin a level in a person with symptoms may indicate the presence of a tumor, but it is not specific for the type of tumor or its location.
