VET 231                                                            Diagnostic Laboratory Procedures I

3 credit hours                                                     Spring Semester 2003

 

Prerequisites:  All previous Vet Tech courses.

 

Textbook:         Laboratory Procedures for Animal Health Technicians. 4th ed. Edited by                

                          Paul W. Pratt, DVM.

 

Methods of Instructions:

                           Lecture; slide presentation, lectures given at UT pertaining to     

                           Hematology, and “hands-on” experience in lab sessions.

 

Course Objectives:

                           The student will be able to perform various laboratory procedures

                           pertaining to hematology and will have a workable knowledge of the

                           theories involved.

 

Course Description:

                           This course will familiarize students to the laboratory equipment used

                            in veterinary clinics and hospitals.  The course includes a complete

                            description of laboratory procedures involving hematology, which

                            the student may come in contact with in veterinary practice.

 

Course Requirements:

                            Student must attend lectures and complete all reading assignments.

 

Units of Instruction:

                            Composition of Blood

                            Plasma/Serum

a.        liquid portion of blood

b.       color variations (Icterus index)

c.        function

Red Blood Cells

a.        physical description

b.       function

c.        composition

d.       life span

e.        erythron

f.         production of cells

g.       determining functional status of the RBC/erythron

h.       erythrocyte count

i.         hemoglobin

j.         abnormal morphology if RBC’s

k.        abnormalities of color

l.         pathological conditions

Leukocytes

a.        functions (general)

b.        special properties

c.        two basic groups

 

Methods of Evaluation:

                                 There will be 5 tests and a comprehensive final.  All are counted equally.  Articles and        

                                  homework will be average as one test grade.  Your lab grade will be based on

                                 performance and a lab final.  Lab is 20% of your grade.  More than one absence in lab

                                 constitutes a drop in a letter grade for each absence.  Lab exams will not be made up.
