MLT 240IN - Urinalysis and Body Fluids

3 Credits, 5 Contact Hours
2 lecture periods 3 lab periods

Introduction to the fundamental clinical lab techniques of urine and body fluids. Includes collection, physical and chemical examination, microscopic examination, body fIuids, and individual fluids.

Prerequisite(s): With a grade of B or better: BIO 205IN , and MAT 151  or assessment into MAT 189 .
Information: Students must be admitted to the Medical Laboratory Technician program or obtain consent of instructor before enrolling in this course. IN is the integrated version of the course with the lecture and lab taught simultaneously.

Course Learning Outcomes
1.   List the normal and abnormal constituents/composition and function of urine and selected body fluids, and   evaluate their clinical significance. 
2.   Discuss evaluation and interpretation of test outcomes and correlate test results with patient condition(s). 

3.   Use the examination of samples to determine the presence of normal and abnormal   constituents/composition of urine and selected body fluids, and evaluate their clinical significance. 
4.   Assess samples for proper collection and perform analysis of urine, fecal, and body fluid samples, including    use and calculations for hemocytometer counting chamber.
5.   Evaluate and interpret laboratory test outcomes and correlate test results with patient condition(s). 
6.   Improve critical thinking and organizational skills by attending class, completing assignments, and participating in problem solving discussions.
