Interpretive Data
If only one of the four markers in the Crohn Disease Prognostic Panel is positive, clinical specificity is at least 85 percent. If all four markers are negative and inflammatory bowel disease (IBD) is suspected, testing for ANCA by IFA is recommended to confirm or exclude the possibility of ulcerative colitis (UC).

Compliance Statement A: Analyte specific reagents (ASR) are used in many laboratory tests necessary for standard medical care and generally do not require U.S. Food and Drug Administration (FDA) approval or clearance. This test was developed and its performance characteristics determined by ARUP Laboratories. The U.S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions. This test should not be regarded as investigational or for research use.
