The Cholesterol Lipid Profile is a blood test that evaluates different types of fats (lipids) circulating in the bloodstream. These lipids play an essential role in cell function and hormone production but can increase cardiovascular risk when levels are imbalanced.
This profile provides a detailed breakdown of cholesterol fractions rather than a single total value. By analysing both protective and harmful cholesterol types, it offers a clearer picture of heart disease risk than total cholesterol alone.
The test is widely used in preventive medicine, routine health checks and monitoring of cardiovascular conditions.
You may need this test to assess your risk of heart disease, stroke or other cardiovascular conditions. Abnormal cholesterol levels often cause no symptoms and may remain undetected for years without testing.
Regular lipid testing supports early intervention through lifestyle changes or medical treatment, helping reduce long-term cardiovascular complications.
Symptoms and scenarios where testing is recommended:
You can attend one of our UK partner clinics or arrange a home or hotel visit with a mobile phlebotomist.
Low Levels
Low HDL cholesterol may reduce cardiovascular protection.
Very low cholesterol levels are uncommon but may occur with malnutrition or chronic illness.
Typical UK reference ranges vary by marker and laboratory.
Normal Levels
Balanced lipid levels suggest healthy fat metabolism and lower cardiovascular risk.
Normal ratios indicate good balance between protective and harmful cholesterol.
High Levels
Elevated LDL, non-HDL cholesterol or triglycerides increase the risk of heart disease and stroke.
An increased total cholesterol: HDL ratio reflects higher cardiovascular risk.

Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
