Student Learning Outcomes and Objectives:
  1. Explain the production, formation, distribution, and function of red blood cells and the different forms and variations of hemoglobin.
  2. Identify and differentiate normal and abnormal red blood cell morphology and inclusions on a blood smear and correlate findings with RBC indices.
  3. Classify and differentiate different types of anemias and hemoglobinopathies including patient signs, symptoms, and lab results of each.
  4. Demonstrate the importance of observing universal precautions and proper specimen collection and handling requirements of hematology patient and quality control samples in order to accurately associate test results, and potential discrepancies, with appropriate disease states and conditions.
  5. Demonstrate good interpersonal skills and ability to accept assistance and constructive criticism while maintaining professional and courteous working relationships with fellow students and instructors.
  6. Demonstrate ability to follow written and oral instructions and spend adequate time needed to complete and master assignments and testing techniques using manual or automated equipment while following universal precautions.  Must also be willing to repeat procedures if necessary.
