  1. Veterinary Diagnostics MR. Pace Vet Assisting

  2. Veterinary Diagnostics At the completion of this unit, students will be able to: List common diagnostic procedures used in the veterinary setting Demonstrate how to use a microscope Describe and demonstrate the use of hematology in veterinary diagnostics Describe and demonstrate the use of cytology in veterinary diagnostics Describe the purpose and function of the kidneys and perform a urinalysis Describe and demonstrate the use of imaging equipment in the veterinary setting Describe and demonstrate diagnostic procedures used to identify parasites

  3. What methods have we learned so far to diagnose illness? Other than recognizing symptoms, what type of tests can we do to diagnose disease?

  4. Common Diagnostic Procedures • Blood Testing • Disease tests (positive/negative) • Blood Panels

  5. Common Diagnostic Procedures • Imaging Procedures • X-Rays • Ultrasounds

  6. Common Diagnostic Procedures • Urinalysis • Dipstick • Look at cells under microscope

  7. Common Diagnostic Procedures • Culturing • Bacterial Culture • Fungal Culture

  8. Common Diagnostic Procedures • Cytology • Study of Cells • Study the cells from a sample or smear

  9. Using a Microscope Parts of the microscope

  10. Using a Microscope • Remember: • Use the proper magnification • Scan slide thoroughly • Use course adjustment then fine adjustment • Don’t push the lens through the slide

  11. Hematology • The Study of Blood • Hematologist – One who studies blood • Works in a laboratory

  12. Hematology • Components of blood • 60% Plasma • Cells • Erythrocytes (red blood cells) • Leukocytes (white blood cells) • Platelets

  13. Hematology Where is blood usually drawn?

  14. Hematology • Blood Collection Tubes • Tiger Top • Has gel in the bottom for serum separation

  15. Hematology • Blood Collection Tube • Lavender Top • Has heparin to stop blood from clotting

  16. Hematology • Blood Collection Tubes • Hematocrit Tubes

  17. Hematology • Spin in a centrifuge • Separates blood cells from plasma • Always counter balance every tube you spin!

  18. Hematology • Blood Smear • A thin layer of blood smeared on a microscopic slide • Allows you to see the blood cells and look for abnormalities

  19. Hematology • Blood Smear • RBC’s • A few WBC’s
