Test Code APSYNAP 
Test SYNAPTOPHYSIN, IMMUNOHISTOCHEMISTRY STAIN 
Description In neoplasms with endocrine differentiation, synaptophysin and chromogranin have been found to be the most useful due to their broad spectrum sensitivity and preservation in conventional paraffin-embedding processing. Either or both markers may be employed, when recognition of a process of an endocrine nature is important in the differential diagnosis.
