we were at the ER last night, because yesterday all lexs diapers contained blood. so they had to take a urine sample from her and the rapid test came back with definatly blood but no bacteria, so its being cultured for 48 hours and in the mean time if she continues to have blood in her diapers today, or if she developes a fever i need to take her back to her pedi. its kinda scarey that all this is happening. what if it isnt a bacteria that can be easily taken care of with antibiotics? i tryed googleing everything but all im comming up with is UTIs and she has none of the classic symptoms for them, just blood in the urine.
