Do NHS Health Checks measure cholesterol? 

The NHS Health Check includes a cholesterol test as a core component of its cardiovascular risk assessment. This check-up, designed for adults aged 40 to 74, aims to spot early signs of stroke, kidney disease, heart disease, and type 2 diabetes. By measuring your cholesterol alongside other clinical data points, healthcare professionals can calculate your “heart age” and determine your statistical risk of experiencing a major cardiovascular event over the next ten years. 

What We’ll Discuss in This Article 

• How the cholesterol test is performed during the check-up. 

• The specific lipid markers measured (LDL, HDL, and non-HDL). 

• Who is eligible for a free NHS Health Check. 

• How your results are used to calculate your QRISK score. 

• Common causes of high readings during a routine check. 

• Triggers for a follow-up appointment or specialist referral. 

• Using the BMI Calculator to support your health check preparation. 

How the Test is Performed 

The cholesterol test during an NHS Health Check is typically done using a simple blood test. Depending on your local GP surgery or pharmacy, this may be a “finger-prick” test (where a drop of blood is analysed immediately) or a standard venous blood draw (where the sample is sent to a laboratory). 

Unlike older protocols, you do not usually need to fast before an NHS Health Check cholesterol test. Modern testing focuses on non-HDL cholesterol, which provides an accurate picture of your cardiovascular risk regardless of whether you have recently eaten. 

• Finger-prick Test: Provides immediate results during your appointment. 

• Laboratory Test: Usually takes a few days for results to be processed and returned to your GP. 

• Non-HDL Focus: Measuring all types of “bad” cholesterol in a single reading. 

Eligibility and Frequency 

The NHS Health Check is a preventative service offered to a specific group of people who are not already being managed for certain conditions. 

Who is Eligible? 

You are eligible if you are aged 40 to 74 and do not have a pre-existing diagnosis of: 

• Heart disease or heart failure. 

• Chronic kidney disease. 

• Diabetes. 

• High blood pressure (hypertension) currently being treated with medication. 

• Atrial fibrillation. 

• High cholesterol currently being treated with statins. 

How Often? 

If you fall into the eligible category, you should receive an invitation from your GP or local council once every five years. This interval is designed to catch metabolic changes that occur as you age. 

Feature	NHS Health Check	Diagnostic Blood Test

Incentive	Free service for eligible residents.	Part of standard NHS diagnostic care.

Calculating Your Risk (QRISK) 

The cholesterol reading is not viewed in isolation. It is entered into a tool called QRISK, which combines multiple data points to assess your heart health: 

• Lipid Ratio: Your total cholesterol divided by your HDL (“good”) cholesterol. 

• Blood Pressure: Taken during the same appointment. 

• BMI: Calculated from your height and weight. 

• Lifestyle Factors: Smoking status and alcohol consumption. 

• Demographics: Age, ethnicity, and postcode (to account for social health factors). 

The result is given as a percentage. If your risk of a heart attack or stroke over the next ten years is 10% or higher, your healthcare professional will discuss starting a statin or making significant lifestyle changes. 

Causes of High Readings in a Check-up 

During a routine check, high cholesterol levels are often attributed to several underlying causes: 

• Dietary Habits: High intake of saturated fats and low fibre. 

• Physical Inactivity: Which lowers “good” HDL levels. 

• Undiagnosed FH: Some people discover they have genetic Familial Hypercholesterolaemia during this routine screen. 

• Secondary Conditions: Such as an underactive thyroid (hypothyroidism), which can raise cholesterol levels. 

Triggers for Further Action 

If your NHS Health Check reveals high cholesterol, it acts as a trigger for several possible next steps: 

• Lifestyle Prescription: A referral to a local weight loss, exercise, or smoking cessation programme. 

• Statin Discussion: If your 10-year risk score is high enough to warrant preventative medication. 

• Diagnostic Follow-up: Further tests if your results suggest an underlying condition like diabetes or kidney disease. 

• Specialist Referral: If your readings are extremely high (e.g., total cholesterol above 7.5 mmol/L), suggesting a genetic disorder. 

To Summarise 

The NHS Health Check is a vital preventative tool that uses cholesterol testing to help you understand your long-term heart health. By measuring your lipid levels alongside your blood pressure and BMI, the check-up provides a comprehensive “MOT” for your cardiovascular system. If you are between 40 and 74, attending this check-up every five years is one of the most effective ways to catch “silent” high cholesterol early and take steps to prevent a future heart attack or stroke. 

If you experience severe, sudden chest pain, pain radiating to your jaw or arms, or extreme breathlessness, call 999 immediately. 

You may find our free BMI Calculator helpful for monitoring your own health markers between checks, as your weight is a significant factor in how your NHS Health Check risk score is calculated.
