I have been ill for nearly three weeks now and no tamiflu despite having the whole plethora of symptoms, and two NHS direct doctors and an out-of-hours saying "it's swine flu"
the other day he grudgingly agreed to give me the lowest possible dose of antibiotics for the racking chest infection I've had for three weeks. I called an out-of-hours GP because I felt lousy that evening and he said "double the dose now, and I'll put it on the computer that your gp needs to prescribe some more"
As far as I know, it doesn't matter whether you are swabbed or not. If your DD has symptoms she should get Tamiflu. I would ask to speak to the Prac Manager to see what their policy is. If no luck - speak to the PALS people at your local PCT. Hope DD is better soon.
