What this marker measures
Total cholesterol is a screening marker; the HDL-to-total cholesterol ratio and LDL level provide much more specific cardiovascular risk information. Lifestyle, diet, genetics, and medications all influence cholesterol.
High or low: what it can mean
High Cholesterol (Total)
Total cholesterol above 200 mg/dL is associated with a gradually increased cardiovascular risk over time. However, total cholesterol alone is less informative than the full lipid panel, which breaks down HDL and LDL.

Low Cholesterol (Total)
Very low total cholesterol is uncommon and usually reflects very low LDL. In some contexts it may be associated with hyperthyroidism, malnutrition, or certain genetic conditions.

Lifestyle considerations
- •Foods high in soluble fibre (oats, legumes, fruit) can help maintain healthy cholesterol
- •Regular physical activity supports HDL levels
