Cholesterol Tests in Cardiovascular Health Screening
Understand what a cholesterol test (lipid profile) measures, what your results may indicate, and how lipid screening fits within a broader approach to cardiovascular wellbeing.
What Is a Cholesterol Test?
A cholesterol test — sometimes referred to as a lipid profile or lipid panel — is a blood test that measures the levels of different types of fats (lipids) circulating in your bloodstream. It is a routine component of cardiovascular health screening and is used to help assess potential risk factors associated with heart and circulatory health.
A standard cholesterol blood test typically reports on: Total Cholesterol, LDL Cholesterol (often referred to as “bad” cholesterol), HDL Cholesterol (sometimes called “good” cholesterol), Triglycerides, and the Total Cholesterol/HDL Ratio.
Cholesterol testing is often performed alongside blood glucose tests, as metabolic risk factors such as elevated blood sugar and abnormal lipid levels frequently co-exist and may compound cardiovascular risk when present together.
Understanding Your Cholesterol Results
| Biomarker | Desirable Level (mmol/L) | Notes |
|---|---|---|
| Total Cholesterol | Below 5.0 | Lower levels are generally considered more favourable |
| LDL Cholesterol | Below 3.0 | Often a primary focus in cardiovascular risk assessment |
| HDL Cholesterol | Above 1.2 (women) / 1.0 (men) | Higher HDL levels may be considered protective |
| Triglycerides | Below 1.7 | Can be influenced by diet, alcohol, and physical activity |
| Total Cholesterol/HDL Ratio | Below 4.0 | A lower ratio is generally viewed more positively |
These reference ranges are general educational guidelines. Individual risk factors can all influence what is considered appropriate for you. For more on interpreting blood test numbers, see our guide to understanding reference ranges in blood tests.
Who Should Consider a Cholesterol Test?
- Adults over 40 who have not had a recent lipid profile test
- Individuals with a family history of high cholesterol or cardiovascular conditions
- Those with lifestyle factors such as a high-fat diet, limited physical activity, or smoking history
- People managing weight concerns, as body composition can influence lipid levels
- Younger adults who wish to establish baseline cholesterol readings

NHS vs Private Cholesterol Testing
| Factor | NHS | Private |
|---|---|---|
| Eligibility | Ages 40–74 (NHS Health Check) | Any adult, any age |
| Waiting Time | May vary by GP availability | Usually available within days |
| Scope | Part of broader NHS Health Check | Standalone lipid profile or wider screening |
| Cost | Free at point of access | Fee applies |
Private testing and NHS services are not mutually exclusive. Many individuals use private screening to complement their NHS care. For a full comparison, see NHS vs private screening.
Frequently Asked Questions
Do I need to fast before a cholesterol blood test?
Fasting for 9–12 hours is commonly recommended, particularly if triglycerides are being measured. Water is usually permitted. For detailed preparation advice, see common screening mistakes that can affect your results.
What happens if my cholesterol levels are high?
If your cholesterol test shows elevated levels, we recommend sharing your results with your GP or a qualified healthcare provider. They can assess your overall cardiovascular risk and discuss appropriate next steps.
How often should I have a cholesterol test?
For most adults without known risk factors, every 4–5 years may be appropriate. Individuals with elevated cholesterol or a family history may benefit from more frequent screening.
