Serum Chromogranin A (CgA) Lab Value
Notes
**Note 1**: Chromoganins are a family of proteins in secretory granules found throughout the neuroendocrine system. Serum Chromogranin 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, code a pretreatment CgA of 400 ng/ml as 400. **Note 3**: Code 000 is reserved for exactly 0.0 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 002-979, round values to the nearest ng/ml. **Note 4**: For an uncertain value, record the stated closest value. For example, code a value stated as "less than 5 ng/ml" as 005.Default
