Urine WBC — What It Means in Your Urine Test
New to reading lab reports? Start with our guide to reading a blood test report
This counts white blood cells in your urine under a microscope, which can point to inflammation or infection.
Peering through the microscope, Urine WBC tallies the defence cells present in your sample. A higher tally can gently suggest swelling or an infection somewhere in your waterworks, worth a calm follow-up.
Also known as: White blood cells (urine), Leukocytes (urine), Pus cells (microscopy), WBC (urinalysis), Pyuria
This isn't a case where higher or lower is better. Your body keeps it in a narrow band, and both directions can matter.
