The Role of Analytical Chemistry in Medicine
Experiment: Measuring the Concentration of Glucose in Blood
Materials:
Blood sample Glucose oxidase test strip
* Glucose meter
Procedure:
1. Insert the glucose oxidase test strip into the glucose meter.
2. Apply a small blood sample to the test strip.
3. The glucose meter will measure the concentration of glucose in the blood and display the result in milligrams per deciliter (mg/dL).
Key Procedures:
Blood sample collection:The blood sample must be collected in a clean, sterile container. Test strip preparation: The test strip should be inserted into the glucose meter before applying the blood sample.
Blood application:The blood sample should be applied to the test strip immediately after collection. Meter reading: The glucose meter should be read within a few minutes after applying the blood sample.
Significance:
This experiment demonstrates the importance of analytical chemistry in medicine by measuring the concentration of glucose in blood. Glucose is a sugar that is essential for energy production in the body. However, high levels of glucose in the blood can lead to diabetes, a serious disease that can damage the heart, kidneys, and other organs. By measuring the concentration of glucose in blood, doctors can diagnose and manage diabetes and prevent its complications.
