High cholesterol has symptoms that are harmless or difficult to diagnose; thus, you need a routine screening test for high-cholesterol diagnosis. High cholesterol screening can even do without fasting.

Knowing your total and HDL cholesterol can give you a general idea about your cholesterol levels, if you are not interested in get lipoprotein profile after fasting. Because testing for total and HDL cholesterol does not require fasting.
Screening cholesterol results with the total cholesterol of 200 mg/dL or more, or if the HDL of less than 40 mg/dL, then you will need to have a lipoprotein profile done.
Cholesterol screening recommendation for adults
All adults over 20 years of age are required undergoing a cholesterol-screening test for every five years. If the total and HDL cholesterol levels are repeatedly normal, then you can go longer between tests. If your total cholesterol is a borderline high and lower HDL cholesterol level, then you require more frequent testing.
People with diabetes, heart disease, stroke, or high blood pressure should always need to have a cholesterol-screening test done, no matter what their age is.
Cholesterol screening recommendation for children
For those who have the risk factors such as a family history of high cholesterol, and heart attacks before age 55 in men and before age 65 in women. Cholesterol screening should start as early as age 2 and no later than age 10. For those who are obese or having diabetes and the cholesterol level tests is normal, recommend retesting in three to five years. Patients already treating for high cholesterol should be screening for every two to six months.
Lipoprotein profile test does not need fasting
After analyzing the data from 300,000 people, Cambridge researchers found that results were accurate even if the patient had eaten before the test.
Fasting was recommended, because it is thought that the body needs enough time to digest the food in the system and to clear any fatty particles in the blood. However, data from 68 long-term surveys in 21 countries suggests that this is not the case.
