However, due to the nature of samples, products have been developed in order to minimise sample handling time. Alpha Laboratories offers three key products for the extraction of human faecal Calprotectin for laboratories, clinicians and point of care applications in the UK.
CALEX® Cap is a stool extraction device containing a measured amount of BÜHLMANN calprotectin extraction buffer. It is for exclusive use with all BÜHLMANN calprotectin assays.
The features of the CALEX extraction device are unique in the market. It improves laboratory workflow and efficiency by eliminating the need for sample weighing, pipetting or decanting and enabling direct loading of the extraction device onto ELISA processors.
Ease of use for laboratory personnel and patients
Application as a primary tube for DS2 ELISA robots and many clinical chemistry analysers
An optimised sample dilution for maximum efficiency in stool extraction
Extract stability of 3 days at room temperature allowing batching to suit the laboratory routine
Very high correlation to the gold standard weighing extraction method
Laboratories using CALEX Cap can benefit from the new BÜHLMANN Calprotectin ELISA kit format EK-CAL2-WEX, that is provided without extraction buffer and so reduces cost and waste.
Fully Automated Calprotectin Testing is Here!
The CALEX® Cap from BÜHLMANN already eased the sample preparation challenges, providing rapid, clean and consistent preparation, offering a simplified workflow solution for faecal calprotectin extraction without the need to decant or further dilute samples.
Now modifications to the blue and white caps at either end of the CALEX device, enable them to be used on laboratory track systems for a truly automated hands off approach to faecal calprotectin testing.
The white cap has been rounded so that once the stool has been sampled the CALEX can fit easily into the racks and pucks of laboratory track systems for front loading or full random access mode. The CALEX is then automatically identified from the barcode and centrifuged. The modification to the blue cap enable automated de-capping after which the CALEX is transported on the track to the appropriate analyser for the calprotectin analysis using the BÜHLMANN fCAL turbo before being moved to the automatic sealer and storage area. Results are then automatically reported on the laboratory LIM system.
Combined with the speed of result and wide assay range (20 – 8000µg/g) of the BÜHLMANN fCAL turbo, the new Track CALEX truly revolutionises the approach to Calprotectin testing.

Faecal Calprotectin is a new biomarker which is helping to save money for the NHS by preventing unnecessary procedures on patients by screening out patients with IBS who do not require endoscopies.
The symptoms of functional disorders such as Irritable Bowel Syndrome (IBS) and organic inflammatory intestinal disease (IBD) can be very similar in presentation but are two very different medical conditions.
