2007 The first BÜHLMANN assay, fCAL ELISA, is launched in the UK to enable calprotectin testing is with assay protocol 10-600 μg/g 2009 Quantum Blue fCAL range was first introduced for laboratories with low sample throughput or for use in pointof-care setting, e.g. IBD clinics, or on wards 2010 High range assay protocol is released for fCAL ELISA giving results up to 1800 μg/g, enabling monitoring of IBD patients 2011 Quantum Blue fCAL high range (100-1800 μg/g) became available, ideal for monitoring positive IBD patients 2012 Double plate fCAL ELISA format for higher throughput lab testing made available 2013 Quantum Blue fCAL extended range (30-1000µg/g) was introduced, with results used to aid the diagnosis and monitoring of IBD patients with a single kit format 2014 fCAL ELISA WEX format and CALEX extraction device were launched. Designed for compatibility with the BÜHLMANN assay and offering a significantly improved workflow unlike the more traditional extraction method 2015 IBDoc Calprotectin home test, the first CE marked home test for patients with IBD, became available. The extended range cassette (30-1000µg/g) is used in the IBDoc 2016 BÜHLMANN fCAL turbo is launched in the UK for high throughput calprotectin testing on mainstream analysers. This is the fastest calprotectin assay on the market giving results in just 10 minutes 2017 CALEX Cap is improved in precision and now even closer to the goldstandard weighing method 2020 Launch of the 3rd generation Quantum Blue Reader. This reader is more POC friendly with touch screen, barcode reader or LIMs connection for data entry 2024 Our newest addition, CALEX faecal calprotectin collection kits. These kits streamline the calprotectin testing process and maximise valuable resources in the laboratory, reshaping calprotectin testing workflows Calprotectin Testing - Timeline www.alphalabs.co.uk © 2024 Copyright Alpha Laboratories Ltd. 5
