High Blood Pressure

Why no eating before blood test for cholelest



cholesterol test .why no eating before test


The current guidelines recommend that a person be fasting for 9 to 12 hours before blood drawing for a lipid profile.  The reason is that in a fasting state, the lipid levels are in a steady state (in equilibrium), and can show the presence of high cholesterol and triglyceride levels in the body.

Many foods contain some fat, and the absorption of dietary fat can change the lipid levels in the blood for several hours.  Because the amount of fat in food is hard to quantitate, everyone should be fasting while blood is drawn for a lipid profile.
