Clinical significance:
Tropheryma whipplei (Whipple's disease) DNA, PCR is a highly sensitive and specific method to detect the presence of Tropheryma whipplei DNA in clinical specimens. The diagnosis of Tropheryma whipplei infection should not rely solely upon the result of a PCR assay. A positive result should be considered in conjunction with clinical presentation and additional established clinical tests. Moreover, this assay cannot differentiate between viable and nonviable organisms. A negative PCR result indicates the absence of Tropheryma whipplei DNA at detectable levels in the samples tested and does not exclude the diagnosis of disease.
