The Urine Microscopic: Microscopic Analysis of Urine Sediment (Online CE Course)

(based on 500 customer ratings)

Authors: Betty Smith, MT(ASCP); Kathleen Ann Foster, MS, MT(ASCP) SM
Reviewer: Barbara Cebulski, MS, MLS(ASCP)

This richly illustrated course discusses entities that could be observed in urine sediment, including casts, cellular elements, and crystals. The student will learn to distinguish significant findings from normal findings or artifacts and review the biochemical results that correlate with specific sediment constituents. This course is an excellent review of urine microscopic procedures for clinical laboratory scientists and MLS / MLT students.

Additional Information

Level of instruction: Basic

Intended Audience: Medical laboratory and other healthcare personnel who perform microscopic analysis of urine sediment. This course is also appropriate for medical laboratory science and medical laboratory technician students. 

Course Description: This course covers the basics of urine microscopic examination, including numerous brightfield and phase-contrast images of urinary sediment elements. It is assumed that students have a basic knowledge of urinalysis macroscopic and dipstick examination. The course covers specimen collections and processing, casts, cellular elements, normal and abnormal crystals, parasites, artifacts, and basic biochemical tests to help identify certain elements. It describes a method of quantitation of urine specimens, and emphasizes the intelligent correlation of macroscopic and microscopic results, by the reported technologist.
