What are the Clinical Implications of Chromogranin Levels?
Elevated levels of chromogranin in blood can be indicative of neuroendocrine tumors. Measuring serum chromogranin A is a common diagnostic tool for these conditions. Additionally, chromogranin levels can be used to monitor the progression of neuroendocrine tumors and the effectiveness of treatment. However, elevated chromogranin levels can also be seen in non-neoplastic conditions, such as chronic kidney disease and proton pump inhibitor use, so clinical context is essential for interpretation.
