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.

Forms:

1. Epidermal Nerve Fiber Density Patient Information Sheet (Supply T702) in Special Instructions

2. Epidermal Nerve Fiber Density Instructions (Supply T703) in Special Instructions

 

Preferred:

Specimen Type: Skin punch biopsy tissue

Collection Instructions:

1. A Skin Punch Biopsy Kit containing fixatives, buffer, and cryoprotectant is required (no substitutions accepted). For ordering information, call 507-284-8065.

2. Prepare and transport specimen per instructions on the Epidermal Nerve Fiber Density Instructions (Supply T703) in Special Instructions.

Additional Information: Neurology Clinical Notes information is required on Epidermal Nerve Fiber Density Patient Information Sheet (Supply T702) in Special Instructions

Specimen Stability: Refrigerated (preferred)/Ambient

 

Acceptable:

Specimen Type: Slides

Additional Information:

1. Slides reacted with PGP9.5 are required.

2. Hematoxylin and eosin-stained slides and Congo red-stained slides are optional.

Specimen Stability: Ambient (preferred)/Refrigerated

 

Specimen Type: Tissue block and PGP9.5-reacted slides

Collection Instructions:

1. Slides reacted with PGP9.5 are required.

2. Tissue block will be used to create hematoxylin and eosin-stained slides and Congo red-stained slides.

Specimen Stability: Ambient (preferred)/Refrigerated

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.
