Signs of age, or something more?

My 10-year-old crossbreed, Titch, had her routine booster a month ago together with a Wellpet blood test. This test showed that she had elevated levels of one of the liver enzymes. The figure should normally be no more than 212 but hers was 475. As she was showing no symptoms and it was only one of the enzymes (I'm not sure which one) we decided to retest in a month to see if it changed. We have just retested and the level has gone up again to 559. My vet says at this stage it is nothing to be too concerned about as if the liver was severely diseased the enzyme level would be up in the thousands, but the fact that it is rising means that, in her opinion, we should maybe do a few more tests to see of we can figure out what is going on. She is recommending a liver stimulation test and an ultrasound initially.

Having done a little research, I have read that it is often quite normal for middle aged dogs to have elevated liver enzymes and it doesn't always indicate a real problem. The suggestion seems to be that it may be better to wait and retest again in six months unless adverse symptoms start to appear.

At the moment Titch seems perfectly healthy. She is fit and active, is not drinking or urinating excessively and does not have any signs of fluid retention. I adopted Titch from a rescue centre when she was about nine months old and she has always had a tendency to occasionally vomit up bile, but I have had another dog who did this, almost seeming to purge himself when his stomach was empty, and so have never thought that might indicate a problem. It is a very infrequent occurrence since her stomach is very rarely empty (!), unlike the stomach of my other dog, who was not food orientated at all and would often go two or three days without eating anything.

Any suggestions about what might be going on here? I don't really want to start putting her through a whole load of tests if it turns out to be a false alarm, and while she is insured my insurer will only cover 35 per cent of the costs after the £95 excess so it could prove to be expensive.

Any advice would be welcome!

Many thanks,
