What is LDL Cholesterol?
Also written as：LDL-C ／ Bad Cholesterol
LDL cholesterol is a lipoprotein that carries cholesterol throughout the body. When levels are too high, it accumulates in artery walls and promotes atherosclerosis, which is why it is called "bad" cholesterol. It is used to evaluate dyslipidemia and to assess the risk of myocardial infarction and stroke.
Reference range guideline
In health checkups, a level of 140 mg/dL or above is generally classified as "high LDL cholesterolemia." Treatment target values are set individually based on risk factors such as the presence or absence of diabetes and atherosclerotic disease, and may be set at below 120 mg/dL or below 100 mg/dL, among others.
* Reference ranges vary by testing facility, measurement method, age, sex, and other factors. Please check the reference range printed on your result sheet.
How to interpret an out-of-range result
Elevated levels increase the risk of atherosclerosis. A physician will evaluate the result together with diet, exercise, and other lifestyle factors, as well as other lipid, blood glucose, and blood pressure values.
