Using Glucotest-what's normal?

[Anonymous]

Because Saffy, a new diabetic, is high stress, fractious and difficult to handle (has to be made woozy in an anesthesia cage at the vet to get a blood test) I am not able to do at-home BG monitoring. But I did purchase a couple of Purina's Glucotest kits for the litter box when she was lethargic and I suspected she was getting too much insulin. (Vet had recommended to either watch her or bring her back in for another vet BG reading with possibility of anesthesia-can't afford that!)
With the Glucotest she was showing no sugar at all in her urine the first day so I cut her back from 2 units PZI BID to 1 unit PZI BID. She started showing some sugar in her urine and finally stabilized out at a steady "150" reading over a couple of days. When I reported this to the vet he was very pleased and said to stick with the 1 unit - that I had been right about her getting too much. He was also pleased about the Glucotest kits and said it was a good way to keep an eye on her until I felt ready to afford a fructosamine test.
But I forgot to ask him... what IS a "normal" urine reading? Is it different from BG readings? What does "150" mean?

A normal reading will have no glucose in the urine. BUT that doesn't tell you if he is getting too much insulin or just the right amount. I have never used the test strips you are using, but if you can keep it around the lowest reading to no sugar reading, you should be fine. Sugar spills into the urine when there is too much in the blood stream, so the kidneys have to start filtering some out.

As Kelly said, if you are only testing urine, you want to always see glucose in the urine so you have some confidence that BGs are not gooing to low.
