Canine CRP Immunoassay
Gentian Canine CRP Immunoassay is an in vitro diagnostic test for quantitative determination of canine CRP in dog serum and plasma. The Gentian Canine CRP Immunoassay is designed and developed using canine specific antibodies and Gentian’s proprietary technology. The measurement of canine CRP is important in diagnosis and treatment of inflammatory disorders in dogs.
Background– Gentian Canine CRP
C-reactive protein (CRP) is a major acute phase protein in dogs [1, 2]. CRP is synthesised by the liver in response to inflammation due to infection and/or tissue damage [3]. The concentration of CRP dramatically increases in various disorders including infection, sepsis and surgical trauma [2, 3].
The early detection of canine CRP, enables precise diagnosis and quick individualised patient decisions, resulting in reduced care time and improved patient outcomes. Measuring canine CRP is beneficial for detecting systemic inflammation, rapid diagnosis, analysis of treatment response and for monitoring disease activity.
Assay Principle
The Gentian Canine CRP Immunoassay is a particle-enhanced turbidimetric immunoassay (PETIA) for in vitro diagnostic testing of CRP in canine serum and plasma samples. The assay is rapidly performed in only 10 minutes and can be applied on a wide range of clinical chemistry analysers.
Calibrator Standardisation
The calibrator for the Gentian Canine CRP Immunoassay is available as a 6-point pre-diluted calibrator kit. The calibrator is adjusted against a commercially available human CRP assay used for Canine CRP determination at the Swedish University of Agriculture Sciences Animal Hospital. No international standard is available for canine CRP.

Canine CRP - Frequently asked questions
C-reactive protein (CRP) is a major acute phase protein in dogs [1, 2]. The protein is synthesised by the liver in response to inflammation due to infection and/or tissue damage [3]. The concentration of CRP dramatically increases in various disorders including infection, sepsis and surgical trauma [2, 3]. Importantly, early detection of canine CRP enables precise diagnosis and quick individualised patient decisions. The result is reduced care time and improved patient outcomes.
Why measure canine CRP in samples from dogs?
CRP is a major acute phase protein in dogs. The concentration of CRP in plasma/serum increases rapidly and significantly during systemic inflammation. Subsequently, the concentration of CRP decreases quickly when the source of inflammation is eliminated [3]. Also, measurement of CRP in canine plasma or serum is useful in both diagnosis of sick dogs and in monitoring the treatment response.
Why is the Gentian Canine CRP Immunoassay specific for dogs?
The Gentian Canine CRP Immunoassay is specific for dogs since the antibodies in the assay are produced by immunising hens with purified canine CRP antigen. The species-specific canine CRP antibodies isolated from egg yolk are then used in the production of the Gentian Canine CRP Immunoassay.
How is the Gentian Canine CRP Calibrator standardised?
The Gentian Canine CRP internal calibration is adjusted against a commercially available human CRP assay used for canine CRP determination at the Swedish University of Agriculture Sciences Animal Hospital.
No international standard is available for canine CRP.
What are the benefits of the avian antibodies in the Canine CRP Immunoassay?
Avian antibodies provide increased sensitivity, as well as decreased background in immunological assays. In contrast to mammalian antibodies, yolk antibodies do not activate the mammalian complement system nor do they react with mammalian rheumatoid factors, mammalian IgG antibodies, or bacterial and mammalian Fc receptors [4]. Thus, yolk antibodies offer many advantages over mammalian antibodies.
On which instruments can the Gentian Canine CRP Immunoassay be run on?
The Gentian Canine CRP Immunoassay is an instrument-independent assay, which can be run on all clinical chemistry analysers. Contact us at info@gentian.no for more information about applications.
