HOW IS ASSESSMENT OF FAECAL CALPROTECTIN USED TODAY?
As the original inventor of fecal calprotetin assays the cut off value 50 mg/kg between normal and pathological levels were established by Calpro, based on ground breaking scientific publications. Calpro has kept this critical cut off unchanged since 2000, and this cut off value was confirmed in a study comparing different ELISAs by Labaere. Since 2005 several manufacturers have launched calprotectin ELISAs; each company does their own independent calibration. However, despite values between assays differ considerably and ELISAs from different manufacturers cannot be used interchangeably, they have all adopted 50 mg/kg as cut off.
