Might I add my personal opinion to the cholesterol debate, but emphasising that you should follow the opinion of your GP.
The values of total cholesterol given by the above posters are correct, BUT,if your cholesterol is above 5, that does NOT mean that you will have a heart attack or stroke in the near future, conversely if your cholesterol is below 5, it does not mean that you will NOT have a heart attack or stroke, tomorrow.
Total blood cholesterol values are of limited value, as 2 of the components High Density Lipoprotein (HDL) and Low Density Lipoprotein (LDL) serve the body in differing ways.
HDL..commonly called "good cholesterol" if raised is good for you.
LDL..commonly called "bad cholesterol" if raised, may be a warning sign to change your lifestyle.
My point and my opinion.....do not get a "hang up" of relative levels of you total cholesterol readings.
