Funny thing I didn't know that our vet offered titre testing till I had to for the doggy camp. I would imagine that any vet can do it. As you read from my previous post, they got all weird about it when I asked about it and made the appt. for it. The holistic vet advertises that they do titres. And they were very happy in providing me the information on it. I would just ask your vet.
I'm still waiting on the results, as apparently it takes quite a number of weeks for the information to be returned. I am now on the lookout for a new vet. There is one in our neighbourhood that just opened up that practices both traditional and conventional.
Good luck! Keep us posted
