Range: Low – High
What it generally measures
This is a combined measurement rather than a single particle type — labs typically calculate it from LDL, HDL, and triglycerides measured in the same sample.
Common units on reports: mg/dL
Why people track it over time
People often look at total cholesterol alongside its components (LDL, HDL, triglycerides) rather than on its own, since the same total can come from very different combinations.
