ABSTRACT
IS THE PATIENT’S LIFE AT RISK? ■ Normal urinalysis can include <3 RBCs per high-power field
of centrifuged urine. ■ Hematuria, either microscopic or macroscopic, is defined as
≥3 RBCs per high-power field. ■ In very few circumstances is hematuria deemed life-threat-
ening, but such circumstances do exist and need prompt recognition to prevent morbidity or mortality.
