The great experience gained in the development of Calprest and calprest NG ( Calprotectin in Elisa) allowed Eurospital to contrive a new generation of rapid test comparable to the traditional ELISA assay, designing an innovative system able to detect callprotectin in stool in a wide range (50-1005 mg/kg). Calprotectin concentration is sometimes very high and cannot be quantitative detected by other kits. The calfast XT wide range of quantification leads to the possibility to use it for patient treatment follow up and to have quantitative results without additional and further dillutions.

Calfast XT is a rapid assay and provides with quantitative result of calprotectin concentration in stool by means of the dedicated calfast reader. controls are included in order to supply to laboratories an effective tool for internal control.

In a few minutes Calfast XT provides with faecal concentration of calprotectin using lateral flow technology applied to a support on which the sample is dispensed the coloured band resulting in the card will be detected and quantified by a dedicated reader (calfast Reader). the calfast reader uses a lot specific calibration curve to calculate the calprotection concentration.
