At home cholesterol and blood sugar profile
Home Heart Health Blood Test UK | Cholesterol & Diabetes
A seven marker home blood test combining a full standard lipid profile with HbA1c.
The panel measures cholesterol fractions, triglycerides and longer term blood glucose. It can help identify important cardiovascular risk factors, but it cannot diagnose heart disease or calculate a complete personal risk score by itself.
Formal risk assessment also considers age, sex, blood pressure, smoking, ethnicity, family history, kidney disease, diabetes and medicines. In UK clinical practice, QRISK3 may be used where appropriate.
Call 999 for central chest pain or pressure, severe breathlessness, collapse, new facial or arm weakness, speech difficulty or another possible heart attack or stroke symptom. Do not wait for a home test result.

What this heart health profile measures
| Health area | Biomarkers | What they may help show |
|---|---|---|
| Atherogenic cholesterol | LDL and non HDL cholesterol | Cholesterol carried in particles associated with atherosclerotic cardiovascular disease. |
| Overall lipid profile | Total cholesterol, HDL and total cholesterol to HDL ratio | The overall cholesterol pattern used alongside other risk factors. |
| Circulating fats | Triglycerides | Metabolic and dietary context, with very high levels carrying pancreatitis risk. |
| Longer term glucose | HbA1c | Average glucose over approximately two to three months and risk of prediabetes or diabetes. |
Who may consider this test?
This profile may be considered by adults who want to review selected cardiovascular and metabolic risk markers, including those with:
- A personal or family history of high cholesterol
- High blood pressure, overweight or obesity
- A family history of premature heart disease or stroke
- Prediabetes, diabetes risk or an earlier raised HbA1c
- Statin or other lipid lowering treatment requiring clinician directed monitoring
- Diet, weight or alcohol changes being reviewed over time
- A previous raised triglyceride result
- A request from a GP or another qualified clinician
A home result cannot replace blood pressure measurement, examination, ECG, imaging or urgent assessment of symptoms.
Fasting and collection guidance
| Testing point | Recommended approach |
|---|---|
| Routine cholesterol testing | Most routine lipid profiles can be measured without fasting. |
| Triglycerides or calculated LDL | A clinician or laboratory may request a fasting sample when triglycerides are high or a more controlled comparison is needed. |
| HbA1c | Fasting is not required because HbA1c reflects longer term glucose. |
| Repeat comparisons | Use similar fasting status, medicine timing and collection conditions when comparing results over time. |
| Do not fast unsafely | Seek advice before fasting if you use insulin, sulfonylureas or another medicine that can cause low glucose, or if you need to eat regularly. |
How the home heart health blood test works
Review preparation
Check fasting instructions, medicines, recent illness, alcohol and previous lipid results.
Collect and return
Collect capillary blood into the supplied microtainer and return it using the provided packaging.
Review the complete risk picture
Interpret the laboratory values with blood pressure, smoking, age, family history and medical conditions.
Preparing for the test
| Preparation | What to do |
|---|---|
| Fasting status | Follow the kit instructions and record whether the sample was fasting or non fasting. |
| Water | Plain water is normally allowed and may help capillary collection. |
| Alcohol | Avoid unusually heavy alcohol intake before testing because it can raise triglycerides. |
| Medicines | Record statins, fibrates, diabetes medicines, steroids, retinoids, hormone treatment and other relevant medicines. Do not stop prescribed treatment yourself. |
| Recent illness | Acute illness can affect lipids and glucose. Delay non urgent testing until recovered where practical. |
| Pregnancy and blood conditions | Record pregnancy, anaemia, haemoglobin variants, blood loss or transfusion because they may affect HbA1c interpretation. |
| Previous results | Keep previous lipid and HbA1c values available so changes can be interpreted over time. |
Common result patterns
These simplified examples support discussion and are not diagnoses.
| Pattern | Possible context | Important next step |
|---|---|---|
| High LDL and non HDL cholesterol | May reflect inherited or acquired dyslipidaemia and increased atherosclerotic risk. | Arrange formal cardiovascular risk assessment and consider secondary causes. |
| High triglycerides with raised HbA1c | May occur with insulin resistance, diabetes, alcohol, weight gain or some medicines. | Discuss metabolic assessment and treatment with a GP. |
| Low HDL with raised triglycerides | Can form part of an insulin resistant or metabolic pattern. | Review blood pressure, weight, glucose, smoking and lifestyle factors. |
| Normal total cholesterol but high LDL | The total value may conceal an unfavourable distribution of cholesterol particles. | Use LDL and non HDL values rather than total cholesterol alone. |
| Very high triglycerides | May create acute pancreatitis risk as well as long term cardiovascular risk. | Seek prompt medical review. |
Biomarkers and result interpretation
Select each marker to read what it measures, preparation guidance and how low, normal, high or urgent results may be considered.
LDL cholesterol
LDL carries cholesterol from the liver to tissues. Higher concentrations are causally associated with atherosclerotic cardiovascular disease and are an important treatment target.
The result may be measured directly or calculated from other lipid values. Calculated LDL can become less reliable when triglycerides are markedly raised.
Most routine lipid profiles do not require fasting. Follow the kit instructions. Record whether the sample was fasting, recent alcohol, acute illness, lipid lowering medicines, steroids, retinoids, hormone treatment and any recent major dietary change.
How to understand this result
| Result | What it may mean | What to do |
|---|---|---|
| Critical low | Very low LDL may reflect intensive treatment, genetics, malabsorption, hyperthyroidism or another medical condition. | Discuss an unexpected result with a clinician rather than assuming it is harmful or beneficial by itself. |
| Low | May reflect healthy risk reduction, lipid lowering treatment or genetic factors. | Interpret it with overall cardiovascular risk and treatment goals. |
| Normal | Falls within the laboratory or general comparison range. | A normal LDL does not eliminate cardiovascular risk from smoking, blood pressure, diabetes or family history. |
| Borderline high | May increase long term cardiovascular risk, particularly when other risk factors are present. | Discuss lifestyle, family history and whether formal QRISK3 assessment is appropriate. |
| High | May reflect inherited or acquired dyslipidaemia and increases atherosclerotic risk. | Arrange GP review and assessment of secondary causes and treatment options. |
| Critical high | A very high result can suggest familial hypercholesterolaemia or another important lipid disorder. | Seek prompt clinical review and follow the laboratory escalation advice. |
Total cholesterol
Total cholesterol includes cholesterol carried in LDL, HDL and other lipoprotein particles. It is useful as an overview but is less specific than LDL or non HDL cholesterol.
NHS public guidance commonly uses below 5 mmol/L as a general guide for healthy adults, but individual treatment targets may be considerably lower.
Most routine lipid profiles do not require fasting. Follow the kit instructions. Record whether the sample was fasting, recent alcohol, acute illness, lipid lowering medicines, steroids, retinoids, hormone treatment and any recent major dietary change.
How to understand this result
| Result | What it may mean | What to do |
|---|---|---|
| Critical low | Very low total cholesterol is uncommon and may reflect treatment, low body weight, malabsorption, hyperthyroidism, liver disease or chronic illness. | Discuss an unexpected result with a clinician. |
| Low | May reflect treatment, genetics, diet or another medical factor. | Interpret it with HDL, LDL, non HDL cholesterol and health history. |
| Normal | Falls within the general or laboratory comparison range. | Continue to consider blood pressure, smoking, diabetes and other risk factors. |
| Borderline high | May indicate increased cardiovascular risk depending on the balance of LDL, non HDL and HDL cholesterol. | Review the full profile and formal risk assessment with a GP. |
| High | May arise from inherited factors, diet, diabetes, thyroid disease, kidney disease, liver conditions or medicines. | Arrange clinical review. |
| Critical high | A markedly raised value may indicate familial hypercholesterolaemia or severe secondary dyslipidaemia. | Seek prompt medical review. |
Non HDL cholesterol
Non HDL cholesterol is calculated by subtracting HDL cholesterol from total cholesterol. It includes cholesterol carried by LDL and other potentially atherogenic particles.
It is useful in both fasting and non fasting samples and is a key marker for treatment monitoring in UK cardiovascular guidance.
Most routine lipid profiles do not require fasting. Follow the kit instructions. Record whether the sample was fasting, recent alcohol, acute illness, lipid lowering medicines, steroids, retinoids, hormone treatment and any recent major dietary change.
How to understand this result
| Result | What it may mean | What to do |
|---|---|---|
| Low | Generally indicates a lower concentration of atherogenic cholesterol particles. | Interpret it with treatment status and overall cardiovascular risk. |
| Normal | Falls within the laboratory or general comparison range. | A normal value does not remove risk from blood pressure, smoking or diabetes. |
| High | Indicates a higher burden of cholesterol in potentially atherogenic particles. | Discuss lifestyle, secondary causes and treatment options with a GP. |
| Critical high | A markedly raised result may suggest severe inherited or secondary dyslipidaemia. | Seek prompt clinical review. |
Haemoglobin A1c
HbA1c reflects average blood glucose over approximately the previous two to three months. It helps identify prediabetes or diabetes risk and is used for monitoring people with diagnosed diabetes.
HbA1c is not a current glucose reading and may be misleading in pregnancy, recent blood loss, transfusion, anaemia or haemoglobin variants.
Fasting is not required. Record pregnancy, anaemia, haemoglobin variants, recent blood loss or transfusion, steroids and diabetes medicines.
How to understand this result
| Result | What it may mean | What to do |
|---|---|---|
| Low | May represent low average glucose or shortened red blood cell survival. | Discuss an unexpected low result with a clinician. |
| Below high risk range | Below 42 mmol/mol is generally below the UK prediabetes range for someone without diagnosed diabetes. | Symptoms or very high clinical risk may still require glucose testing. |
| Prediabetes range | 42 to 47 mmol/mol indicates non diabetic hyperglycaemia and increased risk of type 2 diabetes. | Arrange GP review for risk assessment, support and monitoring. |
| Diabetes range | 48 mmol/mol or above is within the diagnostic range when HbA1c is suitable for diagnosis. | Seek prompt clinical review. An asymptomatic person usually needs confirmation. |
| Urgent clinical context | A very high result suggests sustained hyperglycaemia but cannot show current glucose or ketones. | Seek urgent help for vomiting, abdominal pain, deep breathing, dehydration, confusion or drowsiness. |
Total cholesterol to HDL ratio
The total cholesterol to HDL ratio divides total cholesterol by HDL cholesterol. It is used as one component in cardiovascular risk assessment.
A lower ratio is generally more favourable, but the ratio can conceal a high LDL or non HDL concentration and should never replace the individual lipid values.
Most routine lipid profiles do not require fasting. Follow the kit instructions. Record whether the sample was fasting, recent alcohol, acute illness, lipid lowering medicines, steroids, retinoids, hormone treatment and any recent major dietary change.
How to understand this result
| Result | What it may mean | What to do |
|---|---|---|
| Critical low | A very low ratio may reflect high HDL, low total cholesterol, treatment or analytical factors. | Interpret the individual lipid values rather than treating the ratio alone. |
| Low | Usually reflects a favourable balance between total and HDL cholesterol. | Continue to review LDL, non HDL and the wider risk profile. |
| Normal | Falls within the reporting laboratory range. | Use it as one part of cardiovascular risk assessment. |
| High | May reflect higher total cholesterol, lower HDL or both and is associated with higher cardiovascular risk. | Discuss formal risk assessment and treatment options with a GP. |
| Critical high | A markedly high ratio may indicate substantial lipid imbalance. | Seek prompt clinical review. |
HDL cholesterol
HDL transports cholesterol from tissues towards the liver. Lower HDL is associated with higher cardiovascular risk, but attempts to raise HDL directly have not consistently reduced events.
Very high HDL is not automatically protective. The result should be interpreted with LDL, non HDL cholesterol, triglycerides and the wider clinical picture.
Most routine lipid profiles do not require fasting. Follow the kit instructions. Record whether the sample was fasting, recent alcohol, acute illness, lipid lowering medicines, steroids, retinoids, hormone treatment and any recent major dietary change.
How to understand this result
| Result | What it may mean | What to do |
|---|---|---|
| Low | May be associated with insulin resistance, smoking, obesity, inactivity, high triglycerides, some medicines or genetic factors. | Focus on the complete cardiovascular risk profile rather than HDL alone. |
| Normal | Falls within the laboratory or general comparison range. | Continue to review LDL, non HDL and other risk factors. |
| High | Often associated with lower risk, but very high levels can occur because of genetics, alcohol, liver factors or other causes. | Do not assume that high HDL cancels out high LDL or non HDL cholesterol. |
Triglycerides
Triglycerides are fats carried in the blood. Levels can rise after food, alcohol, poorly controlled diabetes, weight gain, kidney or liver disease and some medicines.
Persistent elevation is associated with cardiovascular risk. Very high levels may increase the risk of acute pancreatitis.
Common UK guides use below 1.7 mmol/L for fasting triglycerides and below 2.3 mmol/L for non fasting triglycerides. The reporting laboratory's range takes priority.
Most routine lipid profiles do not require fasting. Follow the kit instructions. Record whether the sample was fasting, recent alcohol, acute illness, lipid lowering medicines, steroids, retinoids, hormone treatment and any recent major dietary change.
How to understand this result
| Result | What it may mean | What to do |
|---|---|---|
| Critical low | Very low triglycerides are uncommon and may reflect low intake, malabsorption, hyperthyroidism, genetics or chronic illness. | Discuss an unexpected result with a clinician. |
| Low | Often not concerning and may reflect diet, treatment or genetic factors. | Interpret it with the complete profile and health history. |
| Normal | Falls within the reference interval for the stated fasting status. | Maintain established cardiovascular risk reduction measures. |
| Borderline high | May reflect recent food or alcohol intake, insulin resistance, weight, medicines or early metabolic disturbance. | Review preparation and discuss repeat testing if needed. |
| High | May be associated with diabetes, alcohol, obesity, kidney disease, liver disease, thyroid disease or medicines. | Arrange GP review and assessment of secondary causes. |
| Critical high | Very high triglycerides may increase the risk of acute pancreatitis. | Seek prompt medical review and follow the laboratory's urgent advice. |
What this panel does not include
| Not included | Why it may matter |
|---|---|
| Blood pressure and QRISK3 | Required for a more complete estimate of ten year cardiovascular risk. |
| Kidney and liver tests | May identify secondary causes and support safe lipid lowering treatment. |
| Thyroid function | An underactive thyroid can raise cholesterol. |
| ApoB and lipoprotein(a) | May provide additional risk information in selected people, particularly with family history or discordant results. |
| hsCRP | Provides selected inflammatory context but is not required for every cardiovascular assessment. |
| ECG, imaging or troponin | Needed for different clinical questions and acute symptom assessment. |

Home heart health blood test FAQs
Can I check my heart health with a home blood test?
Yes. This kit uses capillary blood collected at home and returned for laboratory analysis. It measures selected cholesterol, triglyceride and HbA1c markers, but it does not provide a complete cardiovascular diagnosis or replace a formal NHS risk assessment.
What does this heart health blood test measure?
It reports LDL cholesterol, total cholesterol, non HDL cholesterol, HDL cholesterol, triglycerides, the total cholesterol to HDL ratio and HbA1c.
Is this the same as a full cardiovascular risk assessment?
No. A full assessment also considers age, sex, blood pressure, smoking, ethnicity, family history, kidney disease, diabetes, medicines and other factors. In the UK, clinicians may use QRISK3.
Does this test diagnose heart disease?
No. Cholesterol and HbA1c are risk factors, not direct tests for blocked arteries, heart attack or stroke. Symptoms such as chest pain or sudden weakness require urgent medical assessment.
Do I need to fast for a cholesterol blood test?
Most routine cholesterol profiles can be measured without fasting. A clinician or laboratory may request a fasting sample when triglycerides are high, a calculated LDL is needed, or results are being compared under controlled conditions.
Does HbA1c require fasting?
No. HbA1c reflects average blood glucose over approximately two to three months and does not require fasting.
What is a healthy total cholesterol level in the UK?
For healthy adults, NHS guidance commonly describes total cholesterol below 5 mmol/L as a general guide. Personal targets may be lower when cardiovascular disease, diabetes or other high risk conditions are present.
What is a healthy LDL cholesterol level?
NHS public guidance commonly uses below 3 mmol/L as a general guide for healthy adults. People with established cardiovascular disease or taking lipid lowering treatment may have much lower individual targets.
What is non HDL cholesterol?
Non HDL cholesterol is calculated by subtracting HDL from total cholesterol. It captures cholesterol carried by several potentially atherogenic particles and is useful for treatment monitoring.
What is a healthy non HDL cholesterol level?
NHS public guidance commonly uses below 4 mmol/L as a general guide for healthy adults. Treatment targets are individual and are lower for many people with cardiovascular disease.
What is HDL cholesterol?
HDL transports cholesterol away from tissues towards the liver. A higher HDL can be associated with lower cardiovascular risk, but very high HDL is not always protective and should not be interpreted in isolation.
What is the cholesterol to HDL ratio?
It divides total cholesterol by HDL cholesterol. The ratio is one component used in cardiovascular risk assessment, but it does not replace LDL, non HDL cholesterol or a complete clinical risk calculation.
What is a healthy triglyceride level?
Common UK guides use below 1.7 mmol/L for a fasting sample and below 2.3 mmol/L for a non fasting sample. The laboratory reference interval and collection conditions take priority.
Can high triglycerides be dangerous?
Yes. Persistent elevation is associated with cardiovascular risk. Very high triglycerides can also increase the risk of acute pancreatitis and require prompt medical assessment.
What HbA1c result indicates prediabetes?
In the UK, 42 to 47 mmol/mol is commonly described as non diabetic hyperglycaemia or prediabetes and indicates increased risk of developing type 2 diabetes.
What HbA1c result indicates diabetes?
An HbA1c of 48 mmol/mol or above is within the diabetes diagnostic range when HbA1c is suitable for diagnosis. An asymptomatic person usually needs confirmation with a second qualifying test.
Can a normal cholesterol result mean my heart risk is low?
Not necessarily. Blood pressure, smoking, age, family history, kidney disease, diabetes and other factors may still create substantial risk. A formal clinical risk assessment is more informative.
What can cause high cholesterol?
Possible causes include inherited lipid disorders, diet, obesity, diabetes, an underactive thyroid, kidney disease, liver conditions, alcohol and some medicines.
What can cause low cholesterol?
Low values may occur because of lipid lowering treatment, genetics, low body weight, malabsorption, hyperthyroidism, liver disease or chronic illness. Unexpected or very low results should be interpreted clinically.
Can I use this test to monitor statin treatment?
It may provide useful lipid information, but treatment monitoring should follow the prescriber's requested timing and targets. Do not start, stop or change a statin from a home result alone.
What tests are missing from this heart health panel?
It does not include blood pressure, kidney function, liver enzymes, ApoB, lipoprotein(a), hsCRP, thyroid tests, ECG, imaging or a clinical QRISK3 assessment.
When should heart symptoms be treated as urgent?
Call 999 for central chest pain or pressure, severe breathlessness, collapse, new facial or arm weakness, speech difficulty or another possible heart attack or stroke symptom.
Are the laboratories UKAS accredited and CQC registered?
Samples are processed through UKAS accredited laboratories within a CQC registered diagnostic pathway. Collection equipment is UKCA and CE marked and supported by an ISO 13485 quality management framework.
