Explanation should include the following components:

• RBC count
• WBC count
• Platelets
• Hemoglobin
• Hematocrit
• RBC indices (e.g., mean corpuscular hemoglobin [MCH], mean corpuscular volume [MCV], mean corpuscular hemoglobin concentration [MCHC], red blood cell distribution width [RDW])
• Anticoagulant used for a CBC

Process/Skill Questions:

• What are the formed elements in human blood?
• What is being measured when a medical laboratory professional measures a hematocrit?
• How is oxygen carried from the lungs to the cells?
• What are the correlations between the RBC, hematocrit, and hemoglobin, or the rule of three?
