Lab Test

Tissue for Culture and Histology – Farmington Hills Only


In the event a tissue for both studies must be obtained during non-business hours, it is desirable to submit separate specimens. The tissue for Histology is to be submitted as a routine tissue

(see Surgical Specimen, Routine). The tissue for Microbiology should be submitted without fixative, kept at room temperature, and prevented from drying. Consult Microbiology whether sterile water or sterile saline is desired (depends on test being ordered). Proper Microbiology and Pathology Requisition Forms must be completed and accompany the specimen.

If tissue is submitted in one container for both Microbiology and Pathology studies, the specimen should be collected and sent to Anatomic Pathology fresh without fixative.  The specimen will be divided appropriately before routine testing is performed.  After regular Anatomic Pathology business hours the specimen should be submitted fresh without fixative directly to Microbiology staff or Lab Central Processing staff/medical technologist (midnight shift only) to be processed accordingly.
