Total Cholesterol Normal Ranges
Total cholesterol is the sum of all cholesterol in the blood including LDL, HDL, VLDL, and IDL fractions.
| Age Group | Reference Range | Unit | Notes |
|---|---|---|---|
| Adults (18–64) | 0 – 200 | mg/dL | Desirable |
| Adults (18–64) | 200 – 239 | mg/dL | Borderline high |
| Adults (18–64) | 240 – 9999 | mg/dL | High |
Also reported in: mmol/L.
Why Doctors Order the Total Cholesterol Test
Total cholesterol is used primarily as a screening test and as part of cardiovascular risk calculators. High total cholesterol is a risk factor for coronary artery disease, stroke, and peripheral artery disease.
How to Enter Your Total-C Result
Total Cholesterol can be reported in mg/dL or mmol/L. Choose the unit printed next to your result on the lab report so it is compared with the matching reference range.
What a Low or High Total-C Can Be Associated With
Below the reference range
- Malnutrition and malabsorption
- Hyperthyroidism
- Liver disease (reduced synthesis)
- Cancer and chronic illness
- Statin therapy (treatment effect)
Above the reference range
- Familial hypercholesterolemia (genetic)
- High saturated and trans fat diet
- Hypothyroidism
- Diabetes mellitus and metabolic syndrome
- Nephrotic syndrome
These are common associations, not a diagnosis. A single result is read alongside your symptoms, history and other tests — discuss it with your doctor.
What Can Change Your Total-C Result
Before you read too much into a result, consider whether any of these applied:
- Recent high-fat meal (raises triglycerides and total cholesterol)
- Acute illness (total cholesterol drops during acute infection or MI)
- Pregnancy (physiological rise in all lipids)
- Hypothyroidism (raises cholesterol)
Preparing for the test: Fast for 9–12 hours. Water, plain coffee, and medications are generally allowed.
Symptoms That Often Prompt Total-C Testing
- High cholesterol typically causes no symptoms until complications occur
- Xanthomas (cholesterol deposits under skin) in familial hypercholesterolemia
- Xanthelasma (cholesterol deposits around eyes)
- Chest pain (angina from coronary artery disease)
- Stroke symptoms
