Urinalysis Vs Urine Culture
Normal ranges: The urinalysis report should contain a normal reference range for each item tested. If there are any tests that fall out of that range, it will be flagged as abnormal.

A urine culture should generally be done when symptoms suggest the presence of a UTI regardless of the urinalysis results. ...Read more
