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, apretreatment 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
