Blood test home kit UK
HbA1c and Metabolic Health Blood Test Home Kit UK
A seventeen marker panel built around longer term glucose exposure, with added cholesterol, liver enzyme, kidney, thyroid, iron and vitamin context.
Metabolic risk is often silent and rarely belongs to one result. HbA1c is the anchor, while the remaining markers help place blood sugar within a wider pattern rather than presenting it as an isolated score.
When the test may be useful
Begin with the question you are trying to answer
- A family history of type 2 diabetes or cardiovascular disease
- A previous borderline HbA1c or cholesterol result
- Persistent tiredness with metabolic risk factors
- Reviewing change after a clinician agreed lifestyle plan
Choose a clinical route instead when
- Diagnosing every cause of thirst, fatigue or weight change
- Assessing acute severe hyperglycaemia through the post
- Replacing blood pressure, examination or a complete diabetes assessment

What each metabolic marker contributes
Urea
Urea is a waste product formed when the body processes protein. It is produced through processes involving the liver and removed from the blood mainly by the kidneys. It also contributes to fluid and electrolyte balance. Urea can be influenced by kidney function, liver function, hydration, diet, protein intake, medicines and other medical conditions. People with a history of kidney or liver disease should discuss monitoring with their doctor.
A result in the lowest band can sometimes reflect severe liver dysfunction, poor nutrition, excess fluid intake or another medical condition. Symptoms may include muscle weakness, nausea, vomiting and loss of appetite.
Arrange a prompt medical review.Low urea is uncommon. Possible causes include liver disease, poor nutrition, low protein intake, excess hydration and other medical conditions.
Review the finding with your GP.The laboratory has placed the value inside its stated reference interval and is generally reassuring.
Consider it with creatinine, hydration, symptoms and medical history.A raised urea value can be seen with kidney disease, dehydration, increased protein breakdown, high protein intake, gastrointestinal bleeding or certain medicines. Symptoms may include tiredness, weakness and reduced appetite.
Review the finding with your GP as soon as possible.A result in the highest band can sometimes reflect significant dehydration or severely reduced kidney function. Severe cases may be accompanied by confusion or drowsiness.
Obtain urgent medical advice.Low density lipoprotein cholesterol
Low density lipoprotein cholesterol is commonly called LDL cholesterol. It transports cholesterol through the bloodstream. Raised levels may contribute to plaque within the arteries and increase cardiovascular risk. Diet, activity, weight, smoking, genetics, thyroid health, diabetes and medicines can all affect LDL.
Very low LDL is uncommon. It may reflect medicines, genetics, poor nutrition or an underlying medical condition.
Arrange a medical review if the result is unexpected.Low LDL may be influenced by diet, activity, genetics or medicines such as statins. It is generally favourable in relation to cardiovascular risk.
Consider it with the complete cardiovascular profile.The value sits inside the interval expected by the reporting laboratory and is generally reassuring.
Remember that blood pressure, smoking, diabetes, age and family history also affect risk.A borderline high result may contribute to cardiovascular risk over time.
Discuss it with your GP and consider appropriate lifestyle changes.High LDL can contribute to plaque within the arteries and may be associated with diet, genetics, limited activity, diabetes or thyroid conditions.
See your GP for a cardiovascular risk review.Very high LDL may substantially increase cardiovascular risk and may suggest an inherited cholesterol condition.
Arrange prompt medical assessment.Total cholesterol
Cholesterol is needed for cell structure, hormone production and the absorption of fats and fat soluble vitamins. Raised levels of some cholesterol particles may contribute to cardiovascular disease. Total cholesterol should be considered with LDL, HDL, non HDL cholesterol, triglycerides, cholesterol ratios and personal risk factors.
Very low total cholesterol is uncommon and may be associated with poor nutrition, medicines, thyroid conditions, liver disease, chronic illness or inherited factors.
Discuss an unexpected result with a healthcare professional.Low total cholesterol may occur because of diet, poor nutrition, medicines or medical conditions.
Review it with a clinician if it is unexpected or symptoms are present.The value sits inside the interval expected by the reporting laboratory and is generally reassuring.
Continue to consider wider cardiovascular risk factors.Borderline high cholesterol may be influenced by genetics, diet, weight and limited activity.
Review the finding with your GP.High total cholesterol may increase cardiovascular risk.
See your GP for a complete risk assessment.Very high total cholesterol may substantially increase the risk of heart attack and stroke and can indicate an inherited cholesterol disorder.
Arrange a prompt medical review.Triglyceride to HDL ratio
The triglyceride to HDL ratio compares triglycerides with HDL cholesterol. It is a calculated marker that can provide additional context about cardiovascular and metabolic health. A higher ratio may be associated with an unfavourable lipid pattern, insulin resistance or metabolic syndrome, while a lower ratio is generally considered more favourable. The ratio must be considered with the individual triglyceride and HDL results and other risk factors.
A lower ratio generally reflects lower triglycerides relative to HDL and is usually considered a more favourable metabolic pattern.
Consider it with the full lipid profile and personal risk factors.The ratio falls within the interval used by the reporting laboratory or provider.
Use the written laboratory comment and discuss concerns with your GP.A higher ratio may indicate a less favourable balance between triglycerides and HDL. It may be associated with insulin resistance, metabolic syndrome or increased cardiovascular risk.
Discuss the result with a healthcare professional.Creatinine
Creatinine is a waste product formed through normal muscle activity and removed from the blood mainly by the kidneys. It is commonly used with age, sex and other information to estimate kidney filtration. Creatinine can be affected by hydration, muscle mass, exercise, muscle injury, diet, supplements and medicines.
Low creatinine is uncommon and may reflect low muscle mass, poor nutrition, pregnancy or another medical factor.
Discuss an unexpected result with your GP.The result falls within the reference interval and is generally reassuring.
Kidney health still needs to be considered with symptoms and any calculated filtration result.A raised creatinine value can be seen with reduced kidney filtration, dehydration, muscle injury, intense exercise, supplements or medicines.
Review the finding with your GP as soon as possible.A very high result may indicate significant kidney impairment or another serious medical problem.
Seek urgent medical review.Non HDL cholesterol
Non HDL cholesterol is calculated by subtracting HDL cholesterol from total cholesterol. It represents several cholesterol particles that may contribute to plaque within the arteries.
A low result indicates a lower amount of cholesterol associated with plaque formation and is usually considered favourable.
Consider it with the complete cardiovascular profile.The value sits inside the interval expected by the reporting laboratory and is generally reassuring.
Continue to consider blood pressure, smoking, diabetes and family history.A high result means there is a greater amount of cholesterol that may contribute to cardiovascular risk.
Review the finding with your GP.Iron
Iron is required to produce haemoglobin, the protein that carries oxygen in the blood. A low circulating iron result can be relevant when investigating tiredness, weakness or breathlessness. Serum iron varies during the day and can be influenced by food, supplements and inflammation. It should normally be considered with ferritin, a full blood count and other iron studies where appropriate.
Low iron may be associated with iron deficiency, blood loss, low intake, poor absorption, chronic illness or medicines. Symptoms may include tiredness, weakness and breathlessness.
Discuss the result with a healthcare professional. One low serum iron result does not confirm iron deficiency anaemia on its own.The measured circulating iron level falls within the expected interval.
Speak with your doctor if symptoms remain.A raised iron value can be seen with supplements, hereditary haemochromatosis, repeated transfusions, liver conditions or other causes.
Discuss the result with a healthcare professional.Vitamin B12
Vitamin B12 supports normal brain and nerve function and the production of red blood cells. Sources include meat, fish, eggs, dairy products and fortified foods. Low levels may result from poor intake, pernicious anaemia, reduced absorption, gastrointestinal conditions, surgery or medicines such as proton pump inhibitors.
A very low result may indicate severe deficiency. Symptoms may include muscle weakness, numbness, tingling, walking difficulty, confusion or seizures.
Seek prompt medical advice.Low vitamin B12 may be caused by pernicious anaemia, poor intake, absorption problems or medicines. Symptoms may include tiredness, weakness and tingling.
See your GP to discuss further investigation and treatment.The value sits inside the interval expected by the reporting laboratory and is generally reassuring.
Speak with your doctor if symptoms remain.High vitamin B12 may reflect supplements, injections or treatment. It can also occur with liver, kidney or blood conditions.
Discuss an unexplained high result with your GP.A very high result requires clinical review, particularly when there is no known supplementation or treatment.
Arrange prompt medical assessment.HbA1c
HbA1c reflects average blood glucose exposure over approximately the previous two to three months. It is used to assess long term glucose control and may be used in the diagnosis of prediabetes or diabetes when clinically appropriate. An abnormal result must be interpreted with symptoms, medical history and any reason why HbA1c may be unreliable. People without symptoms may need confirmatory testing before a diagnosis is made.
A lower result can be normal for some people but can also be influenced by shortened red blood cell survival, blood loss or another medical factor.
Discuss an unexpectedly low result with your doctor.The result is below the laboratory threshold used for prediabetes or diabetes.
See your doctor if you have symptoms such as increased thirst, frequent urination, unexplained weight loss or persistent tiredness.The result indicates a higher risk of developing type 2 diabetes. In UK clinical guidance this is commonly 42 to 47 mmol/mol, although the report and clinician interpretation take priority.
Discuss risk reduction, repeat testing and follow up with your GP.The result is within the range used to diagnose diabetes when the test is appropriate. In UK guidance this is commonly 48 mmol/mol or above. A diagnosis may require clinical confirmation.
Arrange a medical review as soon as possible if you are not already known to have diabetes.If diabetes has already been diagnosed, the meaning depends on your individual treatment target. A result cannot be labelled good or poor control without that target and your clinical context.
Discuss the result with your diabetes team, GP or specialist.Cholesterol to HDL ratio
The cholesterol to HDL ratio compares total cholesterol with HDL cholesterol. It provides additional information about the balance between total cholesterol and the cholesterol carried by HDL.
A very low ratio is often favourable, but an unusual result should be considered with the individual values.
Discuss an unexpected result with a healthcare professional.A low ratio may be influenced by diet, activity, genetics or cholesterol lowering medicines and is generally favourable.
Consider it as part of the wider cardiovascular profile.The result suggests a generally favourable balance between total cholesterol and HDL.
Remember that it does not remove all cardiovascular risk.A high ratio may reflect raised total cholesterol, low HDL or both and is associated with greater cardiovascular risk.
See your GP to discuss the result.A very high ratio may indicate substantially increased cardiovascular risk.
Arrange prompt review of the complete lipid profile.Vitamin D
Vitamin D helps the body absorb calcium and supports bones, teeth, muscles and immune function. It is obtained through sunlight exposure, food and supplements. Low vitamin D is common in the United Kingdom, particularly during autumn and winter, in people with limited sunlight exposure and in people with darker skin.
A result in the lowest band can sometimes reflect significant deficiency and requires assessment of the cause and related bone or muscle effects.
Review the finding with a doctor as soon as possible.Deficiency may contribute to muscle weakness, bone pain, osteoporosis and increased risk of falls or fractures.
Discuss treatment and further assessment with your doctor.A lower result can be associated with tiredness, headaches, muscle or bone discomfort or low mood. These symptoms are not specific.
Discuss the result with your doctor.The level is below the preferred interval. Limited sunlight, diet, absorption problems or increased requirements may contribute.
Ask a doctor or pharmacist about suitable measures.Significant deficiency has not been identified.
Persistent symptoms still require assessment.The level is sufficient for normal health functions.
Maintain it with sensible diet, sunlight exposure and appropriate supplementation.The laboratory has placed the value inside its stated reference interval.
Continue sensible measures to maintain vitamin D.The level falls within the range considered favourable by the reporting laboratory.
Avoid unnecessary high dose supplements.High vitamin D is commonly caused by excessive supplementation and can disturb calcium balance.
Arrange a medical review.The result is within a range where toxicity must be considered and may affect the kidneys, bones, muscles, heart and nervous system.
Obtain an immediate medical review.Thyroid stimulating hormone
Thyroid stimulating hormone, known as TSH, is produced by the pituitary gland. It signals the thyroid to produce hormones that influence energy use, metabolism, temperature and many other processes. A high TSH may be associated with an underactive thyroid, while a low TSH may be associated with an overactive thyroid. This product does not include free T4, so an abnormal TSH may require additional thyroid testing.
Very low TSH may be associated with thyroid overactivity, excessive thyroid hormone medicine, thyroid disease, a pituitary condition or other causes.
Review the finding with a doctor as soon as possible.Low TSH may be associated with an overactive thyroid. Symptoms may include anxiety, weight loss, tremor, sweating and heat sensitivity.
See your GP promptly.The laboratory has placed the value inside its stated reference interval and is generally reassuring.
Speak with your GP if symptoms remain.High TSH may be associated with an underactive thyroid. Symptoms may include tiredness, weight gain, constipation, dry skin and cold sensitivity.
See your GP to discuss the result and whether free T4 should be measured.Very high TSH may indicate significant thyroid underactivity or, less commonly, another endocrine condition.
Arrange prompt medical assessment.Aspartate aminotransferase
Aspartate aminotransferase, known as AST, is an enzyme found in the liver, heart, muscles, brain and pancreas. A raised result can occur with liver cell injury, muscle injury, medicines or other medical conditions. AST is not specific to the liver and should be interpreted with ALT, symptoms, medicines, alcohol use, exercise and any other relevant tests.
Very low AST is rarely clinically important. It may be associated with poor nutrition, low vitamin B6 status or other factors.
Discuss an unexpected result with your doctor.Low AST is usually not a cause for concern.
Review it with a clinician if symptoms or other abnormal results are present.The value sits inside the interval expected by the reporting laboratory.
A normal AST does not exclude every liver or muscle condition.A raised AST value can be seen with liver disease, muscle injury, strenuous exercise, alcohol use, heart injury or medicines. Symptoms may include tiredness, abdominal discomfort or jaundice, although many people have none.
Review the finding with your GP.A very high result may indicate serious liver, muscle or other tissue injury. Severe abdominal pain, jaundice or confusion requires urgent assessment.
Obtain an immediate medical review.High density lipoprotein cholesterol
High density lipoprotein cholesterol is commonly called HDL cholesterol. It helps transport excess cholesterol from tissues to the liver. Higher HDL is often associated with lower cardiovascular risk, but it must be considered with the rest of the lipid profile.
Low HDL may be associated with increased cardiovascular risk and can be influenced by genetics, smoking, diet, limited activity and medicines.
See your GP for advice based on your complete risk profile.The value sits inside the interval expected by the reporting laboratory and is generally reassuring.
Consider it with LDL, non HDL cholesterol, triglycerides and personal risk factors.A high HDL result is often considered favourable and may be influenced by genetics, diet and regular activity.
Very unusual values should still be interpreted with the full lipid profile.Alanine aminotransferase
Alanine aminotransferase, known as ALT, is an enzyme found mainly in liver cells. It is commonly measured when reviewing possible liver cell irritation or injury. ALT can be affected by liver conditions, metabolic associated fatty liver disease, alcohol, body weight, infection, intense exercise and medicines.
Low ALT is usually not concerning, although it may occur with poor nutrition, low muscle mass or some treatments.
Discuss it with your doctor if it is unexpected.The value sits inside the interval expected by the reporting laboratory and is generally reassuring in relation to measured liver cell enzyme activity.
A normal ALT does not exclude every liver condition.High ALT may be associated with liver inflammation, fatty liver disease, alcohol, medicines, infection, muscle injury or another condition.
Review the finding with your GP.A very high result may indicate significant liver or tissue injury. Severe tiredness, confusion or jaundice requires urgent assessment.
Seek urgent medical review.Triglycerides
Triglycerides are fats that circulate in the blood and provide energy. Raised levels may contribute to cardiovascular risk. They can be affected by food, alcohol, sugar and saturated fat intake, weight, activity, diabetes, kidney disease, thyroid function, genetics and medicines.
Very low triglycerides are uncommon and may be associated with a very low fat diet, poor nutrition, thyroid overactivity or another condition.
Discuss an unexpected result with your doctor.Low triglycerides may be influenced by diet, activity or genetics and are often considered favourable.
Consider them with the full lipid profile.The value sits inside the interval expected by the reporting laboratory.
Continue to consider the complete cardiovascular profile.A borderline high result may contribute to cardiovascular risk and may be affected by a recent meal, alcohol, weight or metabolic health.
See your GP if it remains raised.High triglycerides may be associated with a diet high in sugar or saturated fat, alcohol, diabetes, kidney disease, limited activity or medicines.
Review the finding with your GP.Very high triglycerides may substantially increase cardiovascular risk and, at particularly high levels, the risk of pancreatitis.
Seek prompt medical advice.Folate
Folate, also known as vitamin B9, supports red blood cell production and normal cell division. It is particularly important before and during pregnancy. Leafy green vegetables, pulses and fortified foods provide folate. People trying to conceive are usually advised to take folic acid, but the appropriate dose should be discussed with a GP or pharmacist.
Very low folate may be associated with poor diet, absorption problems, medical conditions or medicines. Symptoms may include severe tiredness, weakness and irritability.
Review the finding with a doctor urgently.Low folate may be caused by poor intake, poor absorption, increased requirements, alcohol use, medical conditions or medicines.
Discuss the result with your doctor.The value sits inside the interval expected by the reporting laboratory and indicates that the measured folate level is sufficient.
Speak with your doctor if symptoms remain.High folate most often reflects folic acid supplements or fortified foods. High intake can complicate the interpretation of vitamin B12 deficiency.
Discuss an unexpected result and supplement use with a doctor.A very high result may reflect prolonged high dose folic acid use, particularly where neurological symptoms or a possible vitamin B12 problem are present.
Review the finding with a doctor urgently.From order to report

Questions, without the heavy boxes
Common questions
What is the main difference between HbA1c and fasting glucose?
HbA1c estimates average glucose exposure over roughly two to three months. Fasting glucose measures one carefully timed point after an overnight fast.
Can HbA1c diagnose diabetes from one home sample?
A value in the diagnostic range may require confirmation, particularly when symptoms are absent. Some blood conditions and clinical situations can make HbA1c less reliable.
Why are liver enzymes included?
ALT and AST can add context because liver and metabolic health often overlap. They do not diagnose fatty liver or fibrosis.
Does the panel include insulin?
No. It does not directly measure insulin or calculate insulin resistance.
Can I use the result to change diabetes medicine?
No. Prescribed treatment should only be changed with the clinician responsible for your care.
