Our DNA test for Cobalamin Malabsorption is ideal for breeders and owners who want the reassurance of genetic health testing.

The guideline turnaround time for single tests is approximately 10-12 working days after the swab arrives at the lab.

If you need more than two tests it is often more cost-effective to order the relevant breed package.


Cobalamin Malabsorption or Imerslund-Grasbeck Syndrome (IGS) is an inability of the intestine to properly absorb B12 which is needed for cell growth and in the nervous system. Early signs include a loss of appetite and energy, and abnormal growth.

Imerslund-Grasbeck Syndrome is an autosomal recessive condition caused by a mutation in the CUBN gene.
