This module contains a tutorial covering components of blood, blood cell formation, and blood type. In the lab, learners collect their own finger prick blood samples to complete a variety of tests. First, students will prepare a blood smear and identify different blood cells under a microscope. Next, students will determine the hemoglobin concentration of their blood sample using a spectrophotometer and perform a hematocrit test. Finally, students will determine their blood type using Eldon Cards.
