As a rough guide, how much does it cost to test after pups 1st vaccination?

I enquired about my 4 year old being done at my own vet and was quoted a couple of hundred pounds by them. I eventually had the blood taken by them but sent to Glasgow, and that cost around £90.
Vaccicheck appears to be the cheapest if you can find one near you.

Go the vaccicheck route. Some of the pet's at home vets do them for around £40. You can still get your own vet to draw the blood and fill in the forms on their site and pay around the same plus draw of blood too

As suejaw says find a vet that uses vaccines check .I think the pet alliance website has a map showing some or just ring round for one in your area

If she still lives in the same area then her local pet's at home vets do it on site.

Or there is the nearby holistic vets who do one but don't know their prices

I was quoted £60 to have mine tested by a local vet and was also told that this wasn't 100% reliable.  Fwiw

Glasgow test price list 2017

Vets are over charging for titre testing at Glasgow Vet School

Not reliable for the Core diseases, but 100% reliable for rabies, who are they trying to kid ?

Why is it so expensive?  Is it just so that vets get their money one way or t'other?  Or am I just being cynical?

What the vet charges for drawing the blood etc will vary, but I do not think the actual lab testing is overly expensive (I work in a test lab and know the amount of work involved in such testing).

It cost me £65 per dog at a practice that I used purely for the titre testing - my own vet didn't have this service at the time. Have since found another practice that does it for £30 a dog - mine are adults though not pups.

Titre can never be 100% reliable.if .the body has not recently been challenged either by being in contact with the disease or a recent vaccine immunity can still be present but in memory cells which do not show on titres .unless a dog is titred very soon after initial vaccine to prove immunity the dog could be a non responder or mother's immunity could have interfered at.the  beginning and u would never know I would titre shortly  after a vaccine and then no more if immunity was showing . Imo if u are going to titre u need to have decided what you are going to do if the results are not what u want remembering a negative result does not necessarily mean no immunity.

If a dog is a non responder surely there is no point in giving it more vaccine. Or have I misunderstood?

you have understood correctly georgie pig. It doesn't mean that the dog wont gain immunity naturally though

you have understood correctly georgie pig. It doesn't mean that the dog wont gain immunity naturally though. most times we vaccinate and that's it . it is assumed all is well for all we know there could be plenty of dogs wandering around where the vaccine didn't actually confer immunity. I haven't seen any statistics from the vaccines done at different times to show research has been done to say in most cases it works. broadly speaking its why we vaccinate at two or three times as pups hoping at least one does the job.
