My dd had a suspected urine infection last week and the gp tested a sample and said she didn't think it was an infection but she would send off to the hospital anyway. I've just received a call from the GP to advise that she does have an infection and needs antibiotics. They also want her to have an ultrasound as she has had one or two in the past. Health anxiety has shot through the roof thinking all sorts !! And also why was it not detected by the gp when she tested the urine ??!
