Total cholesterol of 6.12 mmol/L is considered borderline elevated. Total cholesterol is the sum of cholesterol contained in all lipoproteins in the blood, including both free cholesterol and cholesteryl esters. The ideal range is <5.18 mmol/L (<200 mg/dl); borderline elevated is 5.18 to 6.19 mmol/L (200 to 239 mg/dl); and elevated is ≥6.22 mmol/L (≥240 mg/dl). Criteria may vary from hospital to hospital. When total cholesterol is elevated it is a risk factor for atherosclerosis and ischemic cardiovascular disease, and in severe cases coronary heart disease, myocardial infarction, and stroke. If the total cholesterol is found to be 6.12mmol/L, attention needs to be drawn to the need for appropriate exercise in daily life, to avoid food, and to adhere to a low-cholesterol light diet. It is recommended that patients with abnormal total cholesterol should go to the hospital in a timely manner, under the guidance of the doctor to actively treat, so as not to delay the condition.
