My 2month Old Daughter And I Just Came Back From

My 2month old daughter and I just came back from the doctor. They tested her urine. Leukocytes 70+, nitrates negative, urobilinogen .2, protein negative, pH 7.0, blood negative, specific gravity 1.010, ketones negative, bilirubin negative, glucose negative.

The doctor said nothing was wrong with her or the urine!! I myself get a lot of urinary infections so I know elevated WBC means infection! She had a UTI 3 weeks ago and was treated for it. Is the doctor correct by saying there is nothing wrong with the urine?
