The Calprotectin Company

Calprotectin Solutions

Calprotectin has been established as a key biomarker in differential diagnosis and follow-up of patients with inflammatory bowel disease, and is also used as a screening tool prior to invasive procedures such as endoscopy.

Calpro produced the first commercial kits available for measuring Calprotectin and thus established cut-offs and standards all subsequent tests would follow.

What is Calprotectin?

Calprotectin is a rather small protein making up around 60% of the cytosol of Neutrophiles. It is released to the surrounding environment when the immune system is activated as a response to microbial or fungal infections and is used in the diagnosis of inflammatory bowel disease (IBD) to differentiate it from the functional irritable bowel syndrome (IBS). It is also routinely used in the follow-up of patients with IBD to predict relapse or determine response to treatment.

Calprotectin is a non-specific biomarker, such as the more commonly used C-Reactive Protein (CRP); however, the stability of the protein, robustness, and local release without need for synthesis makes it a preferred biomarker for IBD. As such, the protein can be and is used in the diagnosis and follow-up of a variety of diseases.

Distant monitoring and E-Health - The future of IBD patient care

E-Health has in recent years emerged as a great tool for patients to remain prolonged periods in remission. E-Health is different from phone or online consultations, in that the latter will only provide the treating physician with the patients' subjective observations. For optimal distant monitoring, objective parameters are also required. When done correctly, e-Health has great benefits for the patient, the physicians, the hospital, and the society as a whole, and can drastically reduce the use of heavy medication, emergency admissions, surgeries, and other expensive treatments.
