Different blood tubes are used for different types of blood tests. For some blood tests the blood needs to clot and for other blood tests the blood is added to some chemicals to prevent the blood from clotting. If the blood glucose is being measured, then the blood is added to a special preservative, etc. Blood tubes come in different sizes and colours depending on the blood test that need to be performed on the blood.
