What is Total Cholesterol?

A measure of all the cholesterol carried in your blood, combining the good and bad types into one number.

Total cholesterol gives a quick overall picture of the cholesterol in your bloodstream and is one of the standard numbers used to think about long-term heart and blood-vessel health. A higher total can be associated with more cholesterol available to build up in the arteries over time, which is linked to greater long-term risk of heart disease and stroke. A markedly low total is uncommon and can occasionally be associated with undernutrition, liver conditions, or a very active thyroid.
