Other Acceptable Specimens

Fixed tissue or biopsy paraffin-embedded block from brain, gastrointestinal tissue, heart valve, lymph node, small intestine, synovial tissue, or other visceral tissue submitted in a sterile container • Minimum 0.5 mL spinal, synovial, or vitreous humor fluid submitted in a sterile plastic vial

Instructions

Submit only 1 of the following specimens
Preferred: Fresh tissue or biopsy (preferred)
Sources: Small intestine tissue (duodenum, ileum, or jejunum)

Specimen Volume: 0.5 mL

Specimens grossly contaminated with blood may inhibit the PCR and produce false-negative results.

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 not likely.
