Caution urged on dipstick screening for haematuria

DIPSTICK screening for haema­turia should be used with caution in asymptomatic patients because pseudo-haematuria is common and false positives occur in up to one-third of tests, specialists are advising.

Any haem-positive dipstick test should be followed up with microscopic urinalysis that demonstrates at least three erythrocytes per high-powered field before initiating further evaluation in all asymptomatic adults, say new best-practice guidelines from the American College of Physicians.
