Foresight Health® Canine Leucocyte Adhesion Deficiency


Our Foresight Health® single test for Canine Leucocyte Adhesion Deficiency 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.


Canine Leucocyte Adhesion Deficiency (CLAD) is a blood disorder affecting the platelets and white blood cells. In Type I white blood cells cannot fight infection and affected dogs usually suffer fatally from severe infections. Onset is usually less than 12 weeks of age. Type III is characterised by prolonged bleeding and chronic infections. Affected dogs can survive for years but are susceptible to severe bleeding with injury or surgery.

Canine Leucocyte Adhesion Deficiency is an autosomal recessive condition caused by a mutation in the ITGB2 (Type 1) or FERMT3 (Type 3) gene.


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