Sensitivity, specificity and accuracy of diagnostic methods.

Test	Sens	Spec	Pro
Serology	15–60%	96–99%	Easily accessible, fast
Serum PCR	66.7%	94.7%	Easily accessible, fast
Histology w/IHC	78–93%	92–100%	Proves intestinal disease
Tissue PCR	96.7%	98.7%	Proves intestinal disease
Fecal PCR	83–96%	67–93%	Less invasive

PCR, polymerase chain reaction; IHC, immune histochemistry.
