We are at the forefront of discovery, focused on improving feline health and welfare by reinvesting profits from this service into research of inherited conditions in cats.

Frequently Asked Questions

Can I have swabs and freepost envelopes?
Yes, please fill out the swab request form, we are happy to post worldwide. Freepost address labels can also be printed, but please note these cannot be used from outside of the UK.

What sample do I need to submit?
If you are an owner or breeder, you will need to submit a mouth swab, we prefer you to use cytobrushes for this – please see ‘how to’ video. Your Veterinary Surgeon may choose to send either a mouth swab or 0.5ml of blood in an EDTA tube.

How many swabs should I send per cat?
One well-taken cytobrush/swab per cat is sufficient. From it we can run many different genetic tests. If you are sending swabs from outside the UK we suggest taking two cytobrushes/swabs from each cat. If the first swab has insufficient DNA we can use the second swab without you having to post another swab.

The results came back as new swab/sample required, what does this mean?
Please view our sampling policy which explains what it means when we request a new swab or sample be submitted.

How long will it take to get the results?
Typical turnaround time is 3 working days from the time we receive the samples. Please note this may be affected by Bank Holidays.

What is my promotional code?
Promotional codes are issued to breed clubs and societies that register with us. Please contact your breed society and ask for the promotional code for genetic testing from “Langford Vets”. If they have not registered with us, please ask them to contact us.

How do I get a promotional code?
Please contact your breed club or society and ask if they have registered with “Langford Vets” for the discount on genetic testing, if they have registered ask them for the promotional code, if not ask them to contact us.

Is my breed club/society already registered with you?
Please check here for a list of registered breed clubs and societies. If your club/society is registered please contact them and ask for the promotional code for genetic testing from “Langford Vets”. If they have not registered with us, please ask them to contact us.

Any discount for more that one cat tested?
We will consider an extra discount if more than 10 cats are tested at the same time. Please email or phone (0117 394 0510) us directly with an idea of the number of cats you are thinking of testing.

Why does my vet need to take the sample/ what is the difference between me taking the sample and my vet taking the sample?
International Cat Care run some “negative genetic registers” and the GCCF run some “active registers”. For cats to be placed on these registers the sample (mouth swab or blood sample) must be taken by a vet who confirms the cat’s identity using its microchip number. The microchip number must be written on the submission form and sample.
We have a dedicated submission form for this purpose, which both the owner and vet must complete. The certificate will state that the cat’s identity was confirmed by a vet and you can use this to register the cat with the ICC negative or GCCF active registers.
If you DO NOT want your cat to go on these registers then you can take a mouth swab and submit it directly to the lab.

Can I have the certificate changed with new information – ie 'Kitten 1' is now called 'Adoring Lightening IIIrd'?
Yes, we would ordinarily be happy to make this change for you without incurring a fee, however, if we have to make a lot of changes we reserve the right to charge an admin fee of £5 per certificate.

I have now had the cat microchipped - please can you update my certificate?
Yes we can do that. Please note this will not allow you to register the cat with the ICC negative or GCCF active registers. This is because the sample that was genetically tested was not originally taken by a vet who checked the cat's identity.

Can you test for my cat’s parentage?
We do not currently offer this service, however we recommend using Animal DNA Diagnostics.

How long do swabs last in the post?
Usually one week, but it can vary. Please also see our sampling policy.

What tests are most popular with other breeders?
PKD, Blood Type and Pyruvate kinase deficiency (PKDef) are popular, but the necessity of these tests depends on the cat breed. Please contact us if you require help deciding which genetic tests are suitable for your breed.

Can I have the results, even though the sample was 'vet submitted' and my vet has the results and the invoice?
If the sample was 'vet submitted' to confirm the cat’s identity….YES, we will email you a copy of the certificate. If the sample was submitted by a vet because the cat was clinically unwell you need to speak to your vet about the result.

Can you resend results from a while ago as my computer has crashed?
Absolutely, please phone (0117 394 0510) or email us your contact details, your cat's name, the lab number (if you have it) and the date the sample was sent. We will be happy to send you a copy.

What do the results mean – my cat is a carrier – what colour will he be?
Please click on the relevant genetic test for an explanation of your test results. If you still have questions, feel free to email or phone (0117 394 0510) us.

Can I have EXTRA tests run on a sample I sent in a while ago?
Yes! We archive ALL DNA samples for at least 2 years. Please complete the online submission form.

Can I have Chlamydia, Calicivirus or Tritrichomonas PCR tests run with you?
Yes, but these MUST be submitted through your vet practice, all results will be sent directly to them and any payment must be made to them. This is because they are infectious diseases rather than inherited diseases. Your vet should have all the information they require, but if they do not then please ask them to contact us (0117 394 0510, email) directly.

Can I genetically test my kitten?
Kittens can be tested from birth, but since they should be removed from the mother 30-60 minutes before sampling we recommend they are not tested until 2-3 weeks of age.

How do I test for Lilac in my Ragdolls?
Lilac is the result of the Dilute gene working on the Chocolate, or Chocolate and Cinnamon genes. Since Cinnamon is not common in Ragdolls we only suggest testing for Chocolate and Dilute. The results must be Chocolate (b/b) and Dilute (d/d) for the Ragdoll to be Lilac.

How do I test for Lilac in my British Shorthairs?
Lilac is the result of the Dilute gene working on the Chocolate, or Chocolate and Cinnamon genes. The results must be Chocolate (b/b) and Dilute (d/d) or Chocolate carrying Cinnamon (b/bI) and Dilute (d/d) for the British Shorthair to be Lilac.

How do I test for Snow colour in my Bengals?
There are three kinds of Snow Bengal - Lynx, Sepia and Mink.
Snow Lynx is caused by the Siamese colourpoint mutation
Snow Sepia is caused by the Burmese colour mutation
Snow Mink is caused by a combination of Siamese and Burmese mutations.
Hence, to check the kind of Snow Bengal you have you need to request Siamese and Burmese colour tests.

Which genetic disease tests are suitable for my breed of cat?
Some genetic disease tests can be performed on many different breeds of cat (e.g. Polycystic kidney disease), whilst others are specific to only one breed of cat (e.g. Ragdoll Hypertrophic cardiomyopathy). We have provided a list of cat breeds and the genetic disease test(s) that are applicable to each breed.
