Specimen Type Describes the specimen type needed for testing

Tissue

Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Sources: Skin or oral mucosa

Container/Tube: Regular serum vials with 10% formalin (Supply T101)

Specimen Volume: Entire specimen

Collection Instructions: For scalp biopsies when the differential diagnosis includes a scarring alopecia, 2 separate 4-mm punch biopsies are recommended (1 for vertical and 1 for horizontal sections). If a single scalp biopsy is received with the clinical diagnosis of a scarring alopecia, the specimen will be processed with horizontal sections.

Additional Information: Biopsy site, physician's name, and clinical diagnosis are required.

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

Size needed depends on diagnosis and size of lesion.
