Chemiluminescence assay (CLIA)

Reporting of results on the day the sample is received (Mon–Sat)

• Reduced concentrations may indicate intestinal malabsorption.
• Increased concentrations are usually the result of supplementation. Occasionally, they may also be seen secondary to various pathological conditions (in dogs and cats>/strong>, particularly gastrointestinal and hepatobiliary diseases).
• Ruminants: Synthesis of vitamin B12 in the rumen can only take place insufficiently if too little cobalt is ingested with the feed. Vitamin B12 deficiency leads to disorders of the energy metabolism with lack of appetite, apathy, growth and performance depression and anaemia as well as possible diarrhoea.
