Serum Chromogranin A (CgA) Lab Value
Notes
**Note 1:** Chromogranins are a family of proteins in secretory granules found throughout the neuroendocrine system. Serum Chromagranin A (CgA) has been shown to be a useful marker for neuroendocrine tumors. **Note 2:** Record, to the nearest nanogram/milliliter (ng/ml), the highest CgA lab value documented in the medical record prior to treatment. * For example, a pretreatment CgA of 400 ng/ml would be recorded as 400 **Note 3:** Code 000 is reserved for exactly 0 ng/ml (no measurable amount of CgA). Do not round tiny values down to 0 ng/ml; any measured value less than or equal to 1 ng/ml should be coded 001. * For code 001, also round 1.1 - 1.4 ng/ml down to 1 ng/ml * For codes 002-980, round values to the nearest nanogram/milliliter **Note 4:** Use code 997 if there is no actual pre-treatment CgA lab value available but an interpretation of the test result is stated.Default
