In TNS affected dogs, neutrophils are produced by the bone marrow, but lack the ability to reach the blood stream. Therefore, affected puppies posses a weak immune system and are not able to fight pathogens effectively. The variable symptoms observed depend on the respective infection. Equally, starting point and severity of the TNS-disease vary, with most of the dogs dying before the fifth month of their live. In rare cases, dogs can live a normal life due to antibiotic- and steroid-therapies.

Breeds: Border Collie

Trait of inheritance: autosomal-recessive


The DNA test is performed out of EDTA blood or buccal swabs. Required swabs can be ordered free of charge. If a swab is sent in, possibly the genetic material is not sufficient to run the test. In this case it would be best to send in an EDTA blood sample.

Testing Procedure

Please send in your sample together with the lab order genetic. Results will be transmitted optionally via post, fax or email. After completion of the test you will receive a separate invoice. Payment can be made via credit card or bank transfer. Breeding club discounts apply if a copy of the membership card is sent together with the respective samples. Due to administrative reasons the invoiced price can not be altered subsequently.
Test duration: 1-2 weeks after arrival of the sample in the lab
