What happens if you don't? Will the result be totally inaccurate?
A fasting lipoprotein profile is used to check how much LDL is contained in your blood. You are asked not to eat for up to 14 hours prior to the test so that your body has enough time to digest the food and to clear any fatty particles from your blood.
If you don't fast an accurate result can not be obtained.
It may be totally wrong depending upon what you have eaten. They need to test your cholestrol level without sudden boosts from your diet.
For example if you had your test after a meal with high cholestrol content, it will make your cholestrol appear higher then it is normally. So to sure that this does not happen they require you to fast before the test.
The results may or may not be wrong depending upon what you ate, so it's best to not eat at all.
Fasting before any blood work is important. It is especially important before you get tested for certain things, like diabetes and cholesterol. The fast serves a very specific purpose: it gives the doctor a reading of your blood he can use to get the answers to his questions about your health.
Eating food means that your body has to process that food, which can take hours. As it processes the food, components of the food breakdown and travel through your blood. Because the cholesterol test checks the level of fat in your blood, any food consumed and the resulting fat it produces in your blood stream can throw the test off completely.
