Advanced Heart Health Test (ApoB, Cholesterol, LDL, HDL, Triglycerides)

Measures ApoB alongside total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides and non-HDL cholesterol. Together these markers provide information about circulating atherogenic particles and the lipid pattern used as part of cardiovascular-risk assessment.

At a glance

• Sample: Finger-prick blood
• Collection: Collect a few drops of blood at home using the supplied kit
• Estimated turnaround: 1–2 working days from laboratory receipt of a usable sample

What this test measures

Apolipoprotein B (ApoB)

A structural protein present on atherogenic lipoprotein particles, including LDL, VLDL and IDL. Because each particle carries one ApoB molecule, the concentration provides an estimate of particle number. An in-range or out-of-range result is not a diagnosis by itself; clinicians interpret it using the laboratory range, symptoms, medical history and related tests.

Total cholesterol

The overall amount of cholesterol carried in the blood across the main lipoprotein classes. Higher values can contribute to cardiovascular risk, but treatment decisions use the full lipid pattern and overall risk rather than total cholesterol alone.

LDL cholesterol

Cholesterol carried in low-density lipoprotein particles, which contributes to atherosclerotic cardiovascular risk when elevated. Higher LDL is associated with greater cardiovascular risk; targets depend on overall risk and whether cardiovascular disease is already present.

HDL cholesterol

Cholesterol carried in high-density lipoproteins and used as one component of cardiovascular-risk assessment. HDL contributes to risk calculations, but a higher value does not cancel the effect of raised LDL or other cardiovascular risk factors.

Triglycerides

A circulating form of fat influenced by recent food intake, alcohol, metabolic health, medicines and inherited factors. A raised result may relate to recent food intake, alcohol, diabetes, medicines or inherited factors; very high levels can increase pancreatitis risk.

Non-HDL cholesterol

Total cholesterol minus HDL cholesterol, representing cholesterol carried across potentially atherogenic particles. A higher result reflects more cholesterol in potentially atherogenic particles and is interpreted with overall cardiovascular risk.

How clinicians use this test

Clinicians use the lipid profile as part of overall cardiovascular-risk assessment. ApoB adds an estimate of the number of atherogenic lipoprotein particles and can be particularly informative when ApoB and LDL cholesterol do not tell the same story. Treatment decisions still depend on overall risk, medical history and current guidance.

Is this the right test for you?

An adult who wants a lipid profile with ApoB for additional cardiovascular-risk context, including someone monitoring an established clinician-led plan. New chest symptoms or other urgent concerns require medical assessment rather than postal testing.

Preparation and collection

The supplier recommends fasting for 10–12 hours with water only, particularly if you have previously had high triglycerides or a clinician requested a fasting lipid profile. If you do not fast, avoid a fatty meal for at least 6 hours before collection. Continue prescribed medicines unless a clinician tells you otherwise.

Understanding your result

Read these markers as a pattern. LDL and non-HDL cholesterol describe cholesterol carried in atherogenic particles, while ApoB estimates their number. Triglycerides are sensitive to recent food and alcohol intake, and HDL contributes context but does not cancel risk from raised ApoB, LDL or non-HDL cholesterol.

Your results and next steps

Review the complete lipid and ApoB pattern with a clinician, especially if you have diabetes, kidney disease, known cardiovascular disease, a strong family history or take lipid-lowering medicine. Do not start, stop or change statins or other treatment from this result alone.

Limitations

This blood test does not calculate your complete cardiovascular risk, diagnose blocked arteries or rule out heart disease. Blood pressure, age, smoking, diabetes, kidney health, family history and existing cardiovascular disease can materially change interpretation and treatment thresholds.

When to get medical help

Do not wait for a home-test result if you feel seriously unwell. Call 999 for a life-threatening emergency, or use NHS 111 when you need urgent advice and are unsure what to do.
