Test Catalog

Test Name

Test ID: WHIPB    
Tropheryma whipplei, Molecular Detection, PCR, Blood

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

See Infectious Endocarditis: Diagnostic Testing for Identification of Microbiological Etiology in Special Instructions.

Specimen Type Describes the specimen type validated for testing

Whole Blood EDTA

Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

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