Informations générales
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 DNA test analyses for two associated mutations (designated ‘b’) that cause type B blood.

Additional Information
The genetic test for determining blood group in cats is available for most domestic breeds, but accuracy for wild cats is unknown due to a lack of reference samples. In a small percentage of all cases, results may be inconclusive due to unidentified genetic variations. This occurs more often in the Maine Coon breed.
The test can determine if a cat likely has serotype B. Please be aware that for Ragdolls and related breeds, additional DNA tests are available for other variants of the b allele as well as the AB allele.
Serological testing (K712) is necessary to precisely determine if the cat has serotype A, B, or AB, and this requires a blood sample. It is important to note that while blood typing tests can provide valuable information, they may not prevent all instances of newborn deaths.
