Just got back from the vet, and they didn't get enough blood from her to do a kidney analysis test, but they did get enough to do blood slides. They wanted to get a sample from her heart, but I said no because there was a good chance that she could die from the procedure.

As far as the color and the crystals on the urates go, the vet had no idea, and neither did her boss. They want to do more bloodwork eventually to determine if there are liver or kidney problems. I am really upset right now, and my worst fears are that she could die, or that she would be miserable and in pain to the point where putting her to sleep would be an option.
