Call the doctor back and let him know she is still throwing up. And ask if the test results are in yet. It really should only take a day for the results to be in, but labs get busy and may put your daughters off, the doc needs to have a rush put on them. Make sure she stays hydrated in the meantime. I had kidney failure several years ago, which I totally could have avoided (another story). The best thing you can do for her is tons of water and pedialyte (and I mean TONS). Have her drinking almost all the time. This will also help flush anything out of her system. Sorry you have to go thru this!! Hope she starts feeling better soon.
