All my horses are SCID tested and now I am thinking about to test all my horses of CA, too!

I had some questions to the test and received this answer mail today:

Hello Martina,

Yes, we accept samples from outside of the United States. The cost for the CA test is $50 US funds. We will need 20-30 mane or tail hairs with the root follicles attached.

You will find the equine CA information, import permit, forms and pricing on the Veterinary Genetics Laboratory Website at: www.vgl.ucdavis.edu  Click on the services icon, click on the horse icon, then click on the shopping cart icon.

You will register for a MyVGL account; fill in your information, the horseʼs information and which test(s) you are requesting. You will print out a bar-coded submission form with instructions and a place to tape the hair follicles.

You have the option to; pay on-line, pay by check or fill out the credit card form that prints out with the bar-coded submission form.

You will receive an email confirmation when your sample arrives into the laboratory. Please allow 5-10 business days for results once the sample arrives into the laboratory. The results will be sent to you via email and a hard copy sent by US mail.

If time is of the essence we recommend you send the sample via FedEx or UPS to the address listed for overnight couriers.
