Correction- Test characteristics of nitrites and leukocytes for UTI

The Urinary tract infection in children, Urinalysis, and Urinary tract infection in adults pages have been updated with more accurate and consistent information about the test characteristics of nitrites and leukocyte esterase for the diagnosis of UTI.
The previous information on the urinary tract infection in children page was particularly inaccurate.
Given the importance of this information it is recommended for all subscribers to be familiar with this new information.
Thanks to Andrew for picking this up.
