The Quantum Blue®  Calprotectin lateral flow assay combines the ease and speed of lateral flow technology (using a highly specific monoclonal antibody to calprotectin), with full quantification by means of a small, telephone sized reading device. The Quantum Blue® Reader analyzes the signal intensity from the test and control line to give a quantitative value and is standardized with the BÜHLMANN fCAL® ELISA.
