Warmblood Fragile Foal Syndrome (WFFS) Test

The AHS may order Warmblood Fragile Foal Syndrome (WFFS) test for horses that we have previously DNA typed by sending the horse’s hair sample to the U.C. Davis lab. If you do not know if your horse qualifies, feel free to call the AHS office and we can tell you.

  • We cannot test horses who do not have a hair sample of file with U.C. Davis lab.  If this is the case for your horse, you will have to create an account on U.C. Davis’ website and order a WFFS test yourself.
  • The fee for ordering a WFFS test through the AHS office is $35.
  • You do need to be the AHS owner of record of the horse to order a WFFS test.  If you are not, you may transfer the horse into your ownership with the proper paperwork and fees.
  • Wait time for results is dependent on UC Davis but generally is 1-2 weeks for WFFS testing. Test results will remain confidential.
  • WFFS testing can be done on foals the same time we are parent-verifying them.
  • WFFS testing through the AHS is offered only for current AHS members.
