Significance of dipstick haematuria. 2. Correlation with pathology.

In an evaluation of a chemical test for haematuria, all patients with positive results or a history of frank haematuria were investigated to determine the source of bleeding. In 10 of the 92 patients in whom the diagnosis was unknown at the time of admission, the presence of haematuria could not be confirmed. Of the remaining 82 patients urinary tract pathology was identified in 74. Of the other eight patients, four had exercise-induced haematuria with no other indications of significant pathology, and in four patients investigations stopped short of renal biopsy because of the patients' age.
