Urinalysis and Body Fluids 6th Edition by Majorie DiLorenzo, Susan Strasinger

Exercise 30

The microscopic of a clear red urine is reported as many WBCs and epithelial cells. What does this suggest?

A. Urinary tract infection

B. Dilute random specimen

C. Hematuria

D. Possible mix-up of specimen and sediment

Step 1 of 2

Urinalysis is done by both macroscopic and microscopic examination.

Macroscopic:

• Analysis viewed by the naked eye.

• It includes urine color, clots clarity, cloudiness and sediments.

Microscopic:

• It helps to analyze microorganisms bacteria, virus etc.., under microscope.

• Presence of white blood cells (WBC), red blood cells (RBC) and epithelial cells are also seen through microscope.

Epithelial cells are normally seen in small quantity in urine.

• Presence epithelial cells in abnormal forms are a problem.

• Microscopic analysis gives accurate type of epithelial cells.

• Epithelial cells are cleared from liquid by centrifuge as sediment.

• In red urine, if WBC is seen in microscope, it means the specimen is mixed up with infected specimen of WBC.

Therefore, WBC’s and epithelial cells in clear red urine suggests “possible mix-up of specimen and sediment”. Hence, the correct answer is option .
