We have analysed over 12 billion heartbeats to date, providing:

Comprehensive heart data capture.
Detection of cardiac arrhythmias (also known as ‘abnormal heart rhythm’) and other related symptoms.
24 hours to long-term activity reports. While a normal resting ECG can detect helpful information about your heart health, it records for approximately 10 - 30 seconds and can miss fleeting arrhythmias. The personal Holter ECG records your heart rhythm over an extended period, allowing more concise data for early detection and optimal patient treatment.
Highly accurate and reliable results analysed by a Cardiac Physiologist.

The device is water resistant, so you can continue with your daily routine – including showering and exercising while wearing it. The device cannot be submerged entirely in water.

What do the reports tell you?

While your symptoms show a piece of the puzzle, our reports reveal the complete picture. It identifies irregular heart rhythms associated with bradycardia, tachycardias, and atrial fibrillation (AFib), a leading cause of stroke.

How do I choose the duration of the device?

How long you wear the device depends on how often you have symptoms. Daily or Multiple Daily Symptoms: If you experience symptoms multiple times a day or nearly every day, a 24-hour (1-day) recording is usually sufficient. Several Times a Week Symptoms: If you experience symptoms several times a week but not daily, a 48-hour (2-day) recording is recommended. Occasional Symptoms: If you experience symptoms only a few times a month or less, a 7-day recording will provide the most complete data. Remember: These serve as guidelines. If you're not sure, consult with us on which option is best for your symptoms.

Cortisol Stress Blood Test

from £45.00

1 Biomarker

Why take this test?

If you are feeling constantly tired, experiencing mood changes, poor sleep or frequent illness, then your body could be under too much stress - it would be worth finding out more about your stress levels. Our Cortisol Blood test will identify if you have abnormal Cortisol levels which could be contributing to your symptoms.

What is cortisol?

Cortisol is a natural hormone. It’s your body’s main stress hormone which is made by your adrenal glands – organs at the top of your kidneys. Having the right balance of cortisol is essential for your health and wellbeing. An abnormal cortisol level might indicate the presence of an adrenal gland disorder or other underlying health problems, which are harmful if left untreated. Too much cortisol can cause “Crushing syndrome”, symptoms of rapid weight gain, easily bruised skin, muscle weakness, diabetes and much more. Too Little Cortisol can cause “Addisons disease”, which leads to changes of your skin, tiredness, muscle weakness, loss of appetite, low blood pressure and much more.

How does the test work?

The simple blood test checks whether your cortisol levels are within the normal range. The normal range for Cortisol is 160 – 600 nmol/L.

How to prepare:

** Take your test around 9am in the morning *** This is when your Cortisol level will be at your nocturnal peak.

Avoid exercise before you take your test - Physical exercise temporarily increases the levels of cortisol in your blood.
Biotin supplements can affect results. Do not take them for two days before the test. Discuss this with your doctor if you have prescribed biotin supplements.
Hormonal contraception can affect the results, so it’s recommended you take a break and use an alternative barrier contraception to get more accurate results. Speak to your GP if you want more information.

Helicobacter Pylori Blood Test

from £105.00

1 Biomarker

In Clinic Test

Why take this test?

To check for the presence of Helicobacter Pylori (H. pylori) bacteria in your stomach, which if left untreated can cause stomach cancer. Many people don't realize they have an H. pylori infection because they never get sick from it.

What is H. Pylori?

Helicobacter Pylori (H. pylori), a common type of bacteria that is contagious and can be passed from person to person through direct contact of saliva, vomit or stool. It can also be passed through contaminated food or water. The bacteria enters your stomach and attacks the lining, causing painful peptic ulcers.

Symptoms of H. pylori:

If you have severe ongoing stomach pain, bloody or black tarry stools or vomit – you should visit a doctor right away. Symptoms from an infection include: • An ache or burning pain in your stomach (abdomen) • Stomach pain that get be worse even when you haven't eaten anything, or your stomach is empty. • Feeling of nausea • Loss of appetite • Frequent burping or bloating in the stomach • Unexplained weight loss

How does the test work?

The simple blood test measures antibodies to H. pylori. Antibodies are proteins made by your body's immune system, which occur when it detects the presence of harmful bacteria to help fight off the illness. A presence of antibodies to H. pylori means you either are currently infected or have been infected in the past. The test cannot tell how long you have had the infection for.

How to prepare:

In general, there's nothing you have to do before the H. pylori blood test, unless otherwise stated by a doctor.

EpiSwitch PSE Advanced Blood Test

from £905.00

2 Biomarkers

In Clinic Test

Testing Accuracy: PSA Test vs. EpiSwitch® PSE

Testing with a standard PSA Prostate Test results in 55% accuracy in detecting prostate cancer. Testing with EpiSwitch® PSE improves your results to 94% accuracy in detection.

Prostate cancer is a concern for many men. Its risk increases with many factors including: age, family history, genetics and ethnicity. The most common prostate cancer test measures your PSA (prostate specific antigen), a protein produced by your prostate, and by prostate cancer cells which increases as you get older and your prostate increases. However, many men who take the PSA test alone and have results of a raised PSA do not always have cancer. By taking the EpiSwitch® PSE Advanced Blood Test alongside or following a private PSA Test, you can make a better-informed decision about your next steps.

EpiSwitch Prostate Screening (PSE) Test from Oxford BioDynamics on Vimeo.

Who should take the EpiSwitch® PSE?

Any man who is being screened for, or is concerned about, prostate cancer.
You may have already been told you have a high or rising PSA level.
You may have trouble urinating, or have other prostate associated symptoms.
You may want peace of mind before starting on a prostate biopsy or treatment plan.

How does the EpiSwitch® PSE Test work?

The EpiSwitch PSE test uses a small sample of blood to measure 5 vital epigenetic changes in your immune cells, and combines these with your PSA (Prostate Specific Antigen PSA Test) score to boost accuracy. A secure report is returned to our doctors within around 5 days after the lab receives your sample, and they will explain the result to you.

What do the results tell you?

Your doctor will receive a personalised EpiSwitch® PSE report informing you if you have a ‘low likelihood’ or ‘high likelihood’ of prostate cancer.

A 'low likelihood' PSE result can offer peace of mind and reduce unnecessary biopsies and over-treatment. This result is consistent with the absence of cancer in more than 9 out of 10 men.
A 'high likelihood' PSE result can help your doctor immediately refer you to the right next step. This result is consistent with cancer being confirmed in more than 9 out of 10 men.

After receiving your report, our doctors will consider this result along with your history to recommend appropriate next steps.

Process for the EpiSwitch® PSE Advanced Blood Test

Weight Loss Blood Test

from £99.00

11 Biomarkers

In Clinic Test

Who should take this test?

This test is ideal for:

Individuals struggling with stubborn weight gain or resistance to weight loss.
People starting or currently on a weight loss injection programme.
Anyone experiencing symptoms such as fatigue, low energy, slow metabolism, mood changes, or cravings.
Those with a history of metabolic conditions (like insulin resistance, thyroid disorders, or high cholesterol).

Why should I take this weight loss blood test?

Weight loss isn’t just about diet and exercise - your body’s internal chemistry plays a huge role. Hormonal imbalances, chronic inflammation, poor blood sugar control, and metabolic sluggishness can all make weight loss harder. Taking this test helps you:

Identify underlying issues that may be hindering your progress.
Customise your weight loss strategy, including medication dosing, nutrition, and lifestyle.
Track improvements as your programme progresses.
Improve your chances of achieving sustainable, long-term results.

What do results tell you?

Your results will reveal: Whether hormones like cortisol, testosterone, and thyroid hormones are helping or hurting your weight loss efforts.

How well your body manages blood sugar and inflammation — two key factors in metabolic health.
Your lipid profile, showing whether your cholesterol levels are within a healthy range.
If you have potential nutritional deficiencies (like iron) that could be contributing to fatigue and reduced performance.These insights allow you and your healthcare provider to make smarter, more effective decisions around your treatment plan.

Biomarkers explained

1. Cortisol A key stress hormone. High levels can trigger fat storage, especially around the midsection, and impact sleep and metabolism. 2. HbA1c Reflects average blood sugar over 2–3 months. Raised levels suggest insulin resistance or diabetes risk — both linked to weight gain. 3. HsCRP An inflammation marker. Chronic inflammation can slow metabolism and increase fat storage. 4. Iron Low iron causes fatigue and reduced exercise capacity — making weight loss more difficult. 5. Testosterone Supports muscle, energy, and fat metabolism. Low levels can lead to fat gain and low motivation. 6. TSH (Thyroid Stimulating Hormone) Regulates thyroid function. Imbalances can affect metabolism and energy. 7. Free T4 (Thyroxine-Free) The active thyroid hormone. Low levels may signal a sluggish metabolism. 8. Lipid Screen Measures cholesterol and triglycerides. Imbalances may point to poor fat processing and higher metabolic risk. 9. Non-HDL Cholesterol Captures all “bad” cholesterol types. High levels are linked to heart and metabolic disease.

NAD Blood Test

from £305.00

2 Biomarkers

In Clinic Test

Measure your NAD levels

The new Blood Test is an easy, at-home kit that helps you check your NAD+ and NADH levels - key molecules involved in energy and cellular health. By knowing your baseline levels, you can make informed and safe decisions about lifestyle choices or supplementation, tailored to your body’s needs. The kit uses advanced technology to provide accurate results from a small blood sample. Results are simple to understand and allow you to monitor your NAD status safely over time, helping you maintain your wellbeing.

What are NAD and NADH?

NAD (Nicotinamide Adenine Dinucleotide) is a vital molecule naturally produced in the body. It plays a key role in converting food into energy, supporting cellular repair, and maintaining overall metabolic balance. NAD declines as we age, so maintaining healthy levels is crucial for overall health, longevity and slowing 'signs of aging'. NAD supplements have recently become highly popular in the UK - to immediately boost NAD levels - helping to promote overall energy, mental clarity and signs of vitality. NADH is the reduced form of NAD and works alongside to help regulate energy production and cellular functions. Together, NAD and NADH are crucial for maintaining cellular health, ensuring your cells have the energy to function efficiently and repair damage over time.

Why take the NAD Blood Test?

NAD levels differ widely between individuals depending on factors such as:

Age
Diet
Lifestyle choices
Underlying health conditions.

Testing your NAD provides an accurate baseline, helping to determine whether supplementation or lifestyle changes are appropriate for you. Sustaining healthy NAD levels is vital to ensure you only take on what your body needs.

Extremely low NAD+: May result from chronic illness, poor diet, or mitochondrial dysfunction; medical evaluation recommended.

Extremely high NAD+: Often caused by excessive supplementation; can disrupt metabolic balance and may lead to vascular inflammation.

Extremely low NADH: Could indicate either efficient energy production or severely depleted NAD levels due to vitamin B3 deficiency or mitochondrial dysfunction.

Extremely high NADH: Commonly linked to mitochondrial dysfunction or over-supplementation.

What will the NAD Blood Test tell me?

Your NAD+ and NADH levels. The test measures both NAD+ (the oxidized form) and NADH (the reduced form) in your blood showing how much energy your cells are producing vs how much they are repairing and regenerating.

Your NAD+/NADH ratio This ratio reflects your cellular redox balance, which is essential for metabolism, energy production, and overall cell function. A healthy ratio indicates that your body is efficiently converting nutrients into energy and supporting cell repair.

Normal ranges:

	Low	High
NAD+ (µM)	20	36
NADH (µM)	0.6	1.8
NAD+/NADH ratio	16.3	45

See a report sample here. Results are not a diagnosis. If your values are outside the healthy reference range, consult a qualified healthcare professional for interpretation and any necessary follow-up.

How does the blood test work?

The test uses a small sample of your blood, which is processed using NADMED Technology to accurately measure NAD and NADH concentrations. Results provide a clear picture of your cellular energy balance, helping identify potential deficiencies or imbalances. This information can then guide personalised supplementation or lifestyle adjustments. Simply book your blood test at home or in-clinic, and receive your results within 7 working days of the sample being received at the laboratory.

What is in the kit?

Each kit includes all materials required for sample collection and return. Any licensed nurse can draw the sample using the enclosed instructions. When booking the blood test, you will receive:

CE-marked blood collection kit
Instructions for taking the sample correctly
