what is fasting blood work?
 An analysis of a blood sample taken with a needle and syringe gives a better indication of health risks. The GP can ask for a full lipid profile test, which not only tests the levels of cholesterol but also of triglycerides. Before having this type of blood test, you will be asked to not eat or drink for 10–12 hours.Because this is a fasting blood test, it can be scheduled for the morning so the fasting period includes when you are asleep at night and therefore normally fasting.
