Test ID: TWRP    
Tropheryma whipplei, Molecular Detection, PCR

Specimen Type Describes the specimen type needed for testing

Varies

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.

The high sensitivity of amplification by PCR requires the specimen to be processed in an environment in which contamination of the specimen by Tropheryma whipplei DNA is unlikely.

 

Forms: If not ordering electronically, complete, print, and send 1 of the following forms with the specimen:

Microbiology Test Request Form (T244) (http://www.mayomedicallaboratories.com/it-mmfiles/microbiology_test_request_form.pdf)

Neurology Test Request Form (T732) (http://www.mayomedicallaboratories.com/it-mmfiles/neurology-request-form.pdf)

 

Submit only 1 of the following specimens:

 

Specimen Type: Fresh tissue or biopsy

Sources: Small intestine tissue (duodenum, ileum, or jejunum), lymph node, other visceral tissue, synovial tissue, gastrointestinal tissue, heart valve, or brain

Container/Tube: Sterile container

Specimen Volume: Entire collection or 5 mm(3)

Collection Instructions: Collect fresh tissue specimen

Specimen Stability Information: Refrigerated <7 days (preferred)/Frozen <7 days

 

Specimen Type: Paraffin-embedded tissue block

Sources: Small intestine tissue (duodenum, ileum, or jejunum), lymph node, other visceral tissue, synovial tissue, gastrointestinal tissue, heart valve, or brain

Container/Tube: Sterile vial

Collection Instructions: Submit formalin-fixed, paraffin-embedded tissue block to be cut and returned; or two to five 10-micron sections in a sterile container

Specimen Stability Information: Ambient (preferred)/Refrigerated

 

Specimen Type: Fluid

Sources: Cerebrospinal, synovial, or vitreous humor

Container/Tube: Sterile vial

Specimen Volume: 0.5 mL

Specimen Stability Information: Refrigerated <7 days (preferred)/Frozen <7 days

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.

Spinal Fluid, Synovial Fluid, or Vitreous Humor Fluid: 0.5 mL/Tissue: 5 mm(3) or two 10-micron sections
