Clinical Info

Aiding in the diagnosis of Whipple disease, especially for identifying inconclusive or suspicious cases, using whole blood specimens

Specimen Type

Blood

Container

Lavender top tube

Collection Instructions

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

Transport Instructions

Specimen Stability

7 Days Room Temperature, Refrigerated of Frozen

Methodology

Real-Time Polymerase Chain Reaction (PCR)

Days Performed

TAT 3 - 8 Days
A positive result indicates the presence of Tropheryma whipplei DNA.

A negative result indicates the absence of detectable T whipplei DNA, but does not negate the presence of the organism and may occur due to inhibition of polymerase chain reaction, sequence variability underlying primers or probes, or the presence of T whipplei DNA in quantities less than the limit of detection of the assay.
