Hematologic studies do not tend to help in the diagnosis of UTIs, although they should be obtained in patients who appear ill. Obtain a complete blood count (CBC) and basic metabolic panel for children with a presumptive diagnosis of pyelonephritis. Perform blood cultures in febrile infants and older patients who are clinically ill, toxic, or severely febrile.
