Analysis of Urine and Body Fluids (AUBF) – Urinary Sediments Practice Test

Mucus and epithelial cells are indeed the most common type of urinary sediment found in normal urine. In healthy individuals, the urinary tract is lined with epithelial cells, and these cells naturally slough off and can be found in the urine. Mucus, produced by the mucous membranes, also contributes to normal urinary sediment and serves as a lubricant and protective layer in the urinary system.

While some presence of red blood cells, white blood cells, and various types of crystals may occur, they are not typically abundant in normal urine. The presence of red blood cells is often associated with injury or disease, while white blood cells can indicate infection or inflammation. Crystals can form under certain conditions but are not a usual finding in healthy urine. Therefore, the predominance of mucus and epithelial cells reflects the normal physiological processes of the urinary tract, making this option the most accurate among those provided.
