Hello everyone! Girls, who has encountered leukocytes in urine of a baby? We have already sent two samples and the urine is bad, the doctor says leukocytes should not be there at all. We're sending her for another urine test on Thursday. And I just don't understand instead of a solution and possible treatment, we're being sent for re-testing ??‍♀️??‍♀️ What if the little girl has an inflammation, but we don't know ? I will say right away that we eat well, the child is cheerful, seems like nothing bothers him. But I am so worried ??Has anyone else experienced this? What could it be? Is it really inflammation?
