[|Human|] My daughter is six years old and went in for her yearly visit today.  A urine sample revealed white blood cells.  they will be sending to the lab for testing.  Should I be concerned.  What is the likely best case and worst case reasons for white blood cells in urine of a 6 yr old female child
[|AI|]  Hello. I just read through your question. Our bodies use white blood cells to fight infection. We all have a baseline number of white blood cells in our bodies. These numbers increase when we have infections, even something as simple as a cold. An excess of white blood cells in the urine can sometimes be a sign of urinary tract infection, but not always. The culture will determine if there is an infection present. If there is, your doctor will prescribe an antibiotic to cure the infection. If there isn't, then there is no concern at all.
