Separate from cells ASAP or within 2 hours of collection. Transfer 1.5 mL serum to an ARUP standard transport tube. (Min: 0.6 mL)
Unacceptable Conditions
Contaminated, heat-inactivated, hemolyzed, or severely lipemic specimens.
Storage/Transport Temperature
Refrigerated.
Stability (from collection to initiation)
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 30 days (avoid repeated freeze/thaw cycles)
Performed
Sun-Sat
Remarks
N/A
Notes
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.
Recommended panel for the evaluation of patients at risk for inflammatory bowel disease. May also be useful in differentiating patients with ulcerative colitis (UC) from those with Crohn disease (CD).
