Parameters developed to Speed UTI Treatment in Children by Anjanee Sharma on March 9, 2021 at 8:37 PM New research sets up parameters for the number of white blood cells that need to be present in children's urine at different concentrations to be diagnosed as a urinary tract infection (UTI). This could help speed treatment of this condition and prevent potentially lifelong complications. UTIs account for about 7% of fevers in children up to 24 months old and are a common cause for emergency room visits. But, Shahid Nadeem, lead investigator, says that since these bacterial infections in infants and toddlers have symptoms similar to other fever-causing conditions, UTIs can be difficult to diagnose.
