Foresight Health® Congenital Myasthenic Syndrome


Our Foresight Health® single test for Congenital Myasthenic Syndrome is ideal for breeders and owners who want the reassurance of genetic health testing.

The guideline turnaround time for single tests is approximately 10-12 working days after the swab arrives at the lab.

If you need more than two tests it is often more cost-effective to order the relevant Foresight Health® breed package.
