False positive dipstick for urinary blood in childhood.
BACKGROUND
In view of the obvious practical advantages, the most common test for hematuria is currently a reagent strip.


METHODS
A standardized microscopic examination of the sediment was performed in 20 asymptomatic children referred for evaluation of chronic isolated microhematuria detected by means of a reagent strip.


RESULTS
In 6 of the 20 children the microscopic examination failed to confirm the result of the dipstick test.


CONCLUSIONS
Confirmation for the presence of hematuria by microscopy is the most important step in children with a positive dipstick for urinary blood.
