One of the reasons for pre-op blood work is to give the vet any indications that she might not do well under anesthesia. Also, I mentioned before, but not all vets automatically include monitoring during surgery, so be certain you ask about that. One of the vets here charges extra for the monitoring, another does not....of course the one that doesn't charge for it does charge a higher fee.
I'm glad you took her in, and now will have her spayed......the possibility of pyometra will be gone then.
