Hi Barbara - I had my vets run a full blood panel before having my girl spayed over the summer. If you want this done then you might have to give them a little warning as not all surgeries can analyse the results and the blood may need to be taken the day before.
JG - I am assuming Barbara is talking about the blood test you mentioned, though it isn't routine to have it done around here

I had the panel run so they could see if there was any problems which could possibly cause complications whilst under GA :)
