The Blood Group AB genetic test for Ragdoll cats (K300) can determine whether your cat likely has Serotype AB (N/b) or not. If negative, it does not determine whether the cat has Serotype A (N/N) or B (b/b).

The serological test (K712) directly determines your cat’s serotype: A (N/N), B (b/b) or AB (N/b). This can only be tested on a blood sample.
