This counts red blood cells seen in your urine under a microscope, even amounts too small to notice.
Under the lens, Urine RBC tallies the red cells drifting through your sample, even quantities far too faint to spot yourself. This closer count can gently point toward something worth reviewing with your care team.
Also known as: Red blood cells (urine), Erythrocytes (urine), RBC (urinalysis), Microscopic hematuria
This isn't a case where higher or lower is better. Your body keeps it in a narrow band, and both directions can matter.
