Foresight Health® Macrothrombocytopaenia


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

Our DNA test results are accepted by the Kennel Club.

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.


Macrothrombocytopaenia (MTCP) is a condition which causes a low blood platelet number but increased platelet size, with these two factors often resulting in an overall normal platelet function. It is important to inform your vet of this condition so they are not concerned by a low platelet count on blood tests.

An autosomal recessive condition caused by a mutation in the TUBB1 gene.


This test is also included in the following Foresight Health® breed packages:
