What Should I Expect from a Cholesterol Check?

Male <40 years old 0.9-1.83mmol / L (30-59mg / dl); Female <40 years old 1.1-2.0mmol / L (33-77mg / dl)

HDL is mainly synthesized in the liver, and its main physiological function is to transport phospholipids and cholesterol. High-density lipoprotein is an anti-atherosclerotic lipoprotein and a protective factor for coronary heart disease. Can promote the elimination of cholesterol in peripheral tissues and prevent the risk of atherosclerosis. High-density lipoprotein molecules carry cholesterol, which is an endogenous cholesterol ester that is reversely transported. It is transported into the liver and then cleared from the blood. High-density lipoproteins take cholesterol from cell membranes, catalyzed by lecithin cholesterol acyltransferase to cholesterol esters, and then carry the cholesterol esters to very low-density lipoprotein and low-density lipoprotein. High-density lipoprotein contains 20% -30% of total human cholesterol.

Clinical significance of high density lipoprotein cholesterol test

Abnormal results: Increase: The main clinical value is the ability to transfer foam cells from atherosclerotic plaques to the liver and excrete them. It can be seen in primary hyperHDLemia (familial hyperalpha-lipoproteinemia) It is found that there are many longevity in this group of families. Patients receiving estrogen insulin or certain drugs (such as niacin, vitamin E, heparin, etc.) can also increase, astaxanthin can significantly increase human high-density lipoprotein cholesterol ^[1] . Decrease: Commonly seen in cerebrovascular disease, coronary heart disease, hypertriglyceridemia, liver function impairments such as acute and chronic hepatitis, cirrhosis, liver cancer, diabetes, smoking, lack of exercise, etc. The decrease can be used as a risk indicator of coronary heart disease.

High density lipoprotein cholesterol test precautions

At the time of examination: the test is performed under the condition that the physiological and pathological conditions are relatively stable, and there should be no acute attack within 4-6 weeks. Before the test: Do not take certain drugs, such as contraceptives, certain antihypertensive drugs, etc., which can affect changes in blood lipids and cause errors in the test. The first day of the inspection was fasting after 8 pm, and water was inaccessible. Before drawing blood, you should maintain a regular diet and keep your weight constant.
