MLT 275IN - Hematology

5 Credits, 7 Contact Hours
4 lecture periods 3 lab periods

The study of red cells, white cells, and platelets looking at structure, formation, and the diseases associated with these cells. Includes types of blood cells, tests, normal and abnormal blood cells, maturation, disease states, hemoglobins, hemoglobinopathies, hemostasis, coagulation, fibrinolytic system, instrumentation, and quality controls and assurance.

Prerequisite(s): With a grade of B or better: BIO 205IN , and MAT 151  or assessment in 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.
  

2.  Discuss RBC and the differences in hemoglobins including clinical significance, electrophoresis results, and red cell indices.

3.  Describe fibrinolytic and coagulation mechanisms, associated laboratory tests (including normal and abnormal findings) and relate these to specific disorders and therapies.

4.  Perform white blood cells (WBC) differentials in various stages of maturation, correlating results with known values (normal 5-10%, abn. 10-20%), inclusions and abnormalities of WBC and red blood cells (RBC) with associated clinical conditions and disease states.

5.  Perform red cell indices calculations from patient complete blood count (CBC) results as well as interpret other hematology test results, including hemoglobin electrophoresis and erythrocyte sedimentation rate (ESR) results.

6.  Perform and interpret the results (including normal and abnormal findings) of fibrinolytic and coagulation laboratory tests, including prothrombin time (PT/INR), activated partial thromboplastin time (APTT), and thrombin time (TT).

7.  Perform automated blood count and coagulation analysis, including application of Westgard Rules, instrument maintenance, quality control, and reporting of results.
