Private LDL7 Subfractions Test in the City of London

Cholesterol is a fatty substance found in the blood. While the body needs cholesterol to build healthy cells, elevated levels can increase the risk of cardiovascular disease. Cholesterol levels are influenced by diet, exercise, body weight, genetics, and other factors.

The NHS recommends that adults have their cholesterol checked regularly, particularly from the age of 40. High cholesterol usually causes no symptoms, which is why blood testing is the only reliable way to assess your levels.

What the LDL7 Subfractions Measures

• Total cholesterol — the overall level of cholesterol in the blood
• HDL cholesterol — often referred to as "good" cholesterol, which helps remove excess cholesterol
• LDL cholesterol — often referred to as "bad" cholesterol, which can build up in artery walls
• Triglycerides — a type of fat in the blood linked to heart disease risk
• Total cholesterol to HDL ratio — a useful measure of cardiovascular risk

When This Test May Be Helpful

• Routine cardiovascular health screening
• A family history of high cholesterol or heart disease
• Over the age of 40
• Diabetes, high blood pressure, or being overweight
• Monitoring the effect of dietary or lifestyle changes
• Monitoring cholesterol-lowering medication (e.g. statins)
• Smoking or a sedentary lifestyle

Understanding Your Results

Results are typically available within 10 days" and are delivered securely.

In the UK, total cholesterol below 5 mmol/L is generally considered desirable for most adults. LDL cholesterol below 3 mmol/L and HDL cholesterol above 1 mmol/L are commonly referenced targets, though individual targets may vary.

Cholesterol levels should be interpreted alongside other cardiovascular risk factors. We recommend discussing your results with your GP, who can provide personalised advice on lifestyle changes or medication if appropriate.
