Not sure what the cholesterol figures of 44 & 70 relate to, next time you visit your surgery to have bloods taken ask for a full lipid breakdown (a full lipid cholesterol check is usually a fasting one but they will say if you need to fast), but here are the current NICE guidelines on cholesterol testing:
Blood fats (lipids)
Lipids are the cholesterol and triglycerides in your blood. Cholesterol is a type of fat found in all of us. You may be familiar with the term blood cholesterol, but what you may not know is that not all cholesterol is bad. Some of it, HDL (high density lipoprotein), can actually protect against heart disease. Low levels of this protective HDL cholesterol increase your risk of cardiovascular disease (CVD). However, LDL (low density lipoprotein) cholesterol is the bad form of cholesterol in the blood. Triglycerides are another type of fat in the blood. If you have raised cholesterol and raised triglycerides you have an increased risk of CVD.
- Your total cholesterol level should be below 4.0mmol/l.
- LDL levels should be less than 2.0mmol/l.
- HDL levels should be 1.0mmol/l or above in men and 1.2mmol/l or above in women.
- Triglyceride levels should be 1.7mmol/l or less.
