TECH124-0907: Basic Hematology - the bloody truth about cats and dogs
Cheryl Stockman, MT (ASCP)
September 13-October 19, 2007
Real Time Sessions: Wednesday evenings; September 19 and 26 and October 3 and 10; 8:30pm-10:00pm ET (USA)
Participants will explore basic hematology concepts applicable to small animal practice with feline and canine patients. The course will include an overview of proper sample handling and processing, in house hematology instrument theory and manual methods involved in a complete blood count. Of course, no hematology course would be complete without a little lab math, so that will also be covered.
The course will have message boards to further discuss the course materials, weekly homework/quiz assignments, reading materials/handouts for reference to correspond with information during the real time sessions and/or in the library materials.
NOTE: This course will not specifically cover individual, in-house instrumentation. Abnormal blood cells and blood parasites will not be thoroughly covered. Phlebotomy and particular venipuncture methods will not be discussed.
Computer aided hematology reading is a nice advance in technology, however, a good clinical pathologist will always make slides for immediate inspection as well as review to aid in a clinical diagnosis. Veterinary support staff should have the ability to assist the veterinarian in this area of diagnostic set up. Veterinary technicians must have these skills as part of their essential skills. Ms. Stockman has been a supervising medical technologist at Tufts University for over 10 years and works closely with Dr. Joyce Knoll in teaching veterinary students. She also has continued practical experience as an assistant in a veterinary hospital giving her the ability to understand and teach in both the academic and general practice fields.
All members of the veterinary support staff are encouraged to join; however, the course is focused towards technicians and experienced assistants. This course is designed for these staff members to have a better understanding of the basics of crossmatching, blood typing, collection and storage of blood, component therapy, transfusion reactions and emergencies. This course has been submitted for RACE approval for veterinarians and veterinary technicians.
Upon completion of this course, participants should be able to:
Week 1: Terminology and Concepts
Content: This week we will discuss terminology used in basic hematology. The concept of CBC will be discussed including the proper collection, handling and storage of the blood specimen. The difference between manual and automated cell counts will be discussed and the process of performing a packed cell volume will be explored. The steps involved in making an adequate blood smear will be illustrated and the need for a good smear will be part of the conversation.
Week 2: Instrumentation, Equipment, and Controls
Content: The discussion this week will be packed with basic hematology instrument theory so that an operator will have some understanding of general measuring principles. This discussion will also include the definition of parameters obtained on an automated analyzer (such as MCH, MCHC, and MCV). There will be basic math presented in the lesson this week. Quality control theory, such as Levy Jennings charting of quality control values will be introduced. Packing time procedure will be incorporated in the discussion as an in-house method of maintaining quality control of the lab centrifuge. The use of a hemocytometer for manual erythrocyte and platelet counts will be examined. This will be a fast-paced week with relevant, but often, overlooked information.
Week 3: Function and Morphology or Erythrocytes
Content: Week 3 will be dedicated to the red blood cell. The function and morphology of erythrocytes will dominate the week's discussion. The concepts of rouleaux and agglutination will be defined and the reticulocyte count and its mathematical correction will be contained in the topical material.
Week 4: Leukocyte Morphology
Content: During this last session, white blood cells will be the main focus. Normal leukocyte morphology will be discussed and abnormal white blood cells will be introduced. It will also be a week to tie up loose ends and get the last minute questions answered on the message board.
Library materials will be made available prior to the topic week so participants will have plenty of time to prepare for the real time sessions and discussion.
MESSAGE BOARD DISCUSSIONS:
Message board discussions regarding the topic presented will begin on the day the course opens and continue for one week following the last real time session. These discussions will be held in the VSPN CE course area.
