Blood Type AB DNA test – All breeds

Cats have several different possible serotypes (blood types): Type A, Type B and the more uncommon Type AB (sometimes known as Type C). Type A is “normal”; Types B and AB can be caused by a number of recessive mutations to the gene CMAH.

Besides being relevant for medical issues such as blood transfusion, a cat’s serotype is significant for breeding. If a kitten with Serotype A is born to a mother with Serotype B, it is at risk from the A-targeting antibodies in the mother’s milk. This causes a potentially lethal reaction known as Feline Isoerythrolysis Neonatalis (IN) or “Fading Kitten Syndrome”.

This test analyses for two associated mutations (designated ‘b’) that cause Type B blood.
