In this third lesson, students will develop an understanding of the procedure and value of a hematocrit which is a routine test before every blood donation.
Healthy red blood cell counts average about 45% of packed red blood cells. In this lesson students will learn how to prepare samples and measure blood volumes to calculate hematocrit values for 3 patient samples.
To further their medical knowledge they will explore the causation and treatment for abnormal hematocrit values and extend this thinking to a current day issue of the use of erythropoietin by athletes. This lesson builds on their knowledge of red blood cells (erythrocytes) and provides more hands on examples of how they can create a demonstration model for an upcoming school/community blood drive.
