Core Course Performance Objectives (CCPOs)

  1. Describe disease morphology and physiology as they relate to hematological diseases and how laboratory tests correlate with these diseases for each of the blood cell lines. (CCC 1, 2, 5; PGC 6).
  2. Explain the general process and disorders of hemostasis and thrombosis. (CCC 1, 2, 5;  PGC 2, 4, 6)
  3. Collect, identify, and describe the types of samples used in hematology, and identify the variables that can adversely affect laboratory results. (CCC 1, 2, 5, 6; PGC 1, 2, 4)
  4. Perform testing of analytes using a variety of methods to include both manual and automated methods. (CCC 2, 3, 4, 6;  PGC 1, 2, 3, 4)
