In domestic cats, the most common blood groups are A and B, while a third rare blood group, AB, is also recognized. This terminology can be confusing because type AB is not the result of a combination of groups A and B.

In Ragdoll cats, three genetic mutations allow determination of the blood group as well as the cat’s status regarding the b allele. This test is particularly important due to the risk of neonatal isoerythrolysis: the colostrum of a mother with blood group B can be fatal to a kitten with blood group A or AB.

This test analyzes mutations specific to the Ragdoll breed and is not applicable to other breeds.
