Overview
Laboratory Findings
Diagnosis is made by intestinal biopsy, which reveals presence of the organism as PAS-positive macrophage inclusions. Immunohistochemical staining for antibodies against T. whipplei has been used to detect the organism in a variety if tissues, and a confirmatory PCR-based assay is also available.
Some of the tests to help diagnose Whipple's disease includes:
- Complete blood count (CBC)
- Polymerase chain reaction (PCR) test to check for the bacteria that causes the disease
- Small bowel biopsy
Whipple's disease may also change the results of the following tests:
- Albumin
- Unabsorbed fat in the stools (fecal fat)
- Intestinal absorption of a type of sugar (d-xylose absorption)
