Special Info
Contaminated, heat-inactivated, hemolyzed, or severely lipemic specimens are unacceptable. This test is New York DOH approved.
Clinical Info
This test may be a useful tool for distinguishing ulcerative colitis (UC) from Crohn disease (CD) in patients with suspected inflammatory bowel disease. ANCA IFA is simultaneously tested on ethanol- and formalin-fixed slides to allow differentiation of C- and P-ANCA patterns.
