## Indications for use
QUANTA Flash Calprotectin is a chemiluminescent immunoassay for the quantitative determination of fecal calprotectin in extracted human stool samples. Elevated levels of fecal calprotectin, in conjunction with clinical findings and other laboratory tests, can aid in the diagnosis of inflammatory bowel disease (IBD) (ulcerative colitis and Crohn’s disease), and in the differentiation of IBD from irritable bowel syndrome (IBS). QUANTA Flash Calprotectin Calibrators are intended for use with the QUANTA Flash Calprotectin Reagents for the determination of fecal calprotectin levels in extracted stool samples. Each calibrator establishes a point of reference for the working curve that is used to calculate unit values. QUANTA Flash Calprotectin Controls are intended for use with the QUANTA Flash Calprotectin Reagents for quality control in the determination of fecal calprotectin levels in extracted stool samples.
