Sample type

A Variety Of Specimens Are Categorized As "Small" Based On Hybrid Criteria (Size/ Complexity/ Cost Of Processing/ Pathologist Time) E.g. Appendix, Bone Biopsy Or Curettings (Bone Resections For Malignancy Are Large Specimens), Branchial Cleft Or Cyst, Breast Biopsy (Mastectomy Specimens Are Large Specimens), Bronchial Biopsy, Cervix Biopsy, Cholesteatoma, Colon Biopsy, Conjunctival Biopsy Or Pterygium, Cornea, Endometrial Curettings, Endoscopic Biopsy, Fallopian Tube, Gall Bladder, Ganglion Cyst, Gastric Biopsy, Gum Or Oral Mucosa Biopsy, Hernia Sac, Hydrocele Sac, Joint & Periarticular Tissue Without Bone, Laryngeal Biopsy, Lung (Needle Or Transbronchial) Biopsy, Lymph Node Biopsy, Nasopharyngeal Biopsy, Oesophageal Biopsy Or Diverticulum, Omentum Biopsy, Oropharyngeal Biopsy, Peritoneal Biopsy, Pleural Or Pericardial Biopsy/ Tissue; Products Of Conception (POCs), Rectal Biopsy, Skin Biopsy, Small Bowel Biopsy, Testis, Testis Biopsy, Thyroglossal Duct, Tongue Biopsy (Tongue With Local Neoplasm Or With Nodes Is Categorized As A Medium Specimen), Tracheal Biopsy, Tonsil Or Adenoids, Ureter Biopsy Or Resection, Urethra Biopsy Or Resection, Vaginal Biopsy Etc.
