More on our SCID test: SCID stands for severe combined immune deficiency, and it is an inherited disorder that can affect pure and part-bred Arabians.
Horses with SCID have no functional immune system, so they cannot fight off infections. There is no treatment for SCID.
SCID is an autosomal recessive disorder. Autosomal disorders are equally likely to affect male or female horses, while “recessive” means that a horse needs to inherit the SCID mutation from both its sire and its dam to be affected. Horses that have inherited the SCID mutation from just one parent are called SCID carriers, and do not have physical signs of this disorder.
To the best of my knowledge, this is the first time that genetic testing for equine SCID has been available in Australia. As an added bonus our price is the best around.
