Specimen(s):
Whole Blood
Collection Medium:
Lavender top tube 3 mL (EDTA)

Interpretive Data:
A positive result is considered diagnostic of Whipple disease.

A negative result does not negate the presence of the organism or active disease, as false negative results may occur due to inhibition of PCR, sequence variability underlying the primers and/or probes or the presence of Tropheryma whipplei in quantities less than the limit of detection of the assay.
Methodology:
Rapid Polymerase Chain Reaction (PCR)
