During a microscopic urinalysis, red and white blood cells are reported per what unit?

In a microscopic urinalysis, the quantities of red and white blood cells are commonly reported per High Power Field (HPF). This measurement unit is significant because it helps standardize the evaluation of urine samples under the microscope. Each HPF represents a specific field of view, and by counting the number of cells present in that field, healthcare providers can assess the presence and significance of these cells in the urine.

Using HPF allows for a consistent approach to quantify and compare the findings across different samples and laboratory settings. The presence of red blood cells can indicate bleeding in the urinary tract, while an elevated number of white blood cells usually suggests infection or inflammation. Consequently, reporting these cells per HPF aids in diagnosing possible conditions affecting the urinary system.

The other options are not typically used for reporting cells in microscopic urinalysis. Milliliters might be used to report the volume of the urine sample but not for cellular counts. Low Power Field is not suitable either, as it would not provide the necessary detail to accurately assess the cellular composition in the sample. Centimeter is an inappropriate unit in this context because it does not pertain to microscopic evaluation.
