Calprotectin Immunoturbidimetric Assay

Calprotectin Immunoturbidimetric (IT) Assay

FDA-cleared and IVDD for the quantitative determination of calprotectin in human stool, in vitro diagnostic use as an aid in the diagnosis of inflammatory bowel disease (IBD), specifically Crohn’s disease (CD) and ulcerative colitis (UC), and as an aid in the differentiation of IBD from irritable bowel syndrome (IBS) in conjunction with other clinical and laboratory findings.


ALPCO’s Calprotectin IT Assay combines the clinical sensitivity and specificity clinicians expect with the efficiency and repeatability today’s laboratories require.
