My daughter is 3 years old and has had a fever for 5-6days now. First couple of days she also was vomiting but that subsided and now is just the fevers. Took her to pediatrician and er send rate is 60 and her hematocrit Level has dropped. Ua showed some leukocyte but waiting for culture to come back...I'm worried and the pediatrician is not exactly saying what he thinks this is. Could you please tell me what this could be? Can the uti cause a high send rate and drop in hematocrit? My daughter otherwise is healthy and looks good. No other symptoms
