The particular selection and letter designations for every case, specimen, and tissue sample will be used to label tissue blocks along with the histologic sections obtained from them. Other letter prefixes might be used to designate the sort of specimen, which include DP for dermatopathology specimens and G for gynecologic pathology specimens. These exceptional quantities are frequently assigned by the pathology details program and to some extent the format might be Paraffin Blocks determined or minimal with the technique in use.
