Test Performed at or Referral Lab Lab Sendouts  (Mayo Medical Laboratories)
Referral Lab number:TWRP


Reference Range:A positive result strongly suggests a diagnosis 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 present of Tropheryma whipplei in quantities less than the limit of detection of the assay.
Use:An aid in diagnosis of Whipple disease, especially for identifying inconclusive or suspicious cases.
