False-positive microhematuria in dipsticks urinalysis caused by the presence of semen in urine.
Positive readings of blood in dipstick urinalysis may indicate trauma or imbalance in hemostasis associated with drug treatment. We evaluated the possibility that the presence of semen in urine may cause false-positive hematuria. ⋯ In men, postcoital urine may be falsely "positive" for microhematuria. This may have implication on the management of male patients in emergency situations such as acute coronary syndromes.
