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

(based on 9527 customer ratings)

Betty Smith, MT(ASCP); Kathleen Ann Foster, MS, MT(ASCP) SM

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 CLS students.

Additional Information

Level of instruction: Basic

Intended Audience: Clinical Laboratory Science Students, and medical technologists and technicians seeking review or continuing education opportunities. It is also appropriate medical students, pathology residents, and pathologists.

Course Description: This course covers the basics of urinalysis 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 dip stick 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.
