Blood sample collection options

You can choose your preferred collection method when you checkout

Home nurse appointment (+£60)

We'll arrange for a medical professional to visit your home and collect your sample. This is great if you're unsure on how it all works or have trouble collecting a sample. No need to book a doctor's appointment or visit a clinic, we'll send you everything you need to collect a sample and post it back to our labs.

Visit a partner clinic (+£45)

Once you've ordered your test, look out for an email from our phlebotomy partners containing information and a link to book your appointment. We'll send you everything the clinic will need to complete the sample and post it back to our labs.

Organise a nurse myself (FREE)

If none of the above options work for you, you can arrange your own medical professional to collect your sample. There is no additional charge for this. Once you've ordered your test, we'll send you everything you and your chosen medical professional will need to collect a sample and post it back to our labs.

Still unsure how it works? You can find more information on collection methods and the service we provide in our 'How it Works' section.

About flexible subscriptions

How does a subscription work?

When you purchase this test subscription plan, we will automatically send you another test kit in a few months. Don't worry - you have full control over when this will be, and you can change/cancel it anytime.

When you first purchase this test, you can choose your subscription options in the checkout. We do this, because we recommend taking multiple tests over time to track how your biomarkers change. You'll be charged per test kit (rather than monthly, for example).

Why subscribe to multiple tests?

One test will show you what areas you need to focus on, continued testing will help you learn how your training, diet and lifestyle is impacting your health.

How often should I test?

We recommend a follow up test 3 months after your first test, followed by a test every 6 months depending on your results, but its up to you!

Can I change what's tested in future tests?

Yes, you can tailor/customise subsequent tests (via your app) to focus on just the areas that need improving.

What this Ultimate Health Check measures

47 Biomarkers

Cholesterol (lipid profile)

5

A cholesterol or lipid panel test measures various cholesterol components to assess cardiovascular disease risk. Early detection of high cholesterol enables lifestyle changes and treatments that can lower cholesterol levels and reduce the risk of heart disease and stroke​.

  • Total Cholestrol
  • LDL
  • HDL
  • HDL: Cholesterol Ratio
  • Triglycerides

Liver health

6

Liver tests, frequently known as liver function tests (LFTs), are a group of blood tests that help assess the health of your liver. These tests measure the levels of various enzymes, proteins, and substances produced or excreted by the liver to detect liver damage, inflammation, or disease.

  • Alkaline Phosphatase (ALP)
  • Alanine amiotransferase (ALT)
  • Gamma GT (GGT)
  • Total Protein
  • Globulin (Calculated)
  • Albumin

Inflammation

2

Inflammation is the body's natural response to injury, disease or infection. Measuring inflammation is important for early disease detection, monitoring chronic conditions, and assessing overall health. It helps identify infections and autoimmune disorders as well as assessing cardiovascular risk.

  • hs-CRP
  • Uric acid

Kidney function

4

Kidney function tests assess how well the kidneys filter waste and balance fluids and electrolytes. Impaired kidney function can lead to toxin buildup, electrolyte imbalances, and anemia, all of which can contribute to fatigue and reduced energy levels.

  • Uric acid
  • eGFR
  • Creatinine
  • Urea

Creatine Kinase

Creatine Kinase (CK) is an enzyme found in muscle. Raised levels of CK are an indicator of muscular micro-damage. This can be associated with high impact or high resistance training load, dehydration, specific medical conditions and some medications. A CK test is useful in helping to prevent overtraining and related injuries.

Omega 6: Omega 3 ratio

Omega-6 and omega-3 are essential fatty acids that must be consumed through diet. A balanced omega-3 to omega-6 ratio is vital for controlling inflammation, supporting cardiovascular and mental health, and ensuring cellular and immune function. The recommended ratio is 3:1, however evidence suggests the average ratio in the UK is much higher at around 15:1.

Vitamins

5

Vitamins are essential nutrients obtained from food and sunlight. They support vital functions like bone health, energy production and fighting infection. Deficiencies can lead to various health issues, including bone disorders, anaemia, low mood and fatigue.​

  • Active B12
  • Vitamin D (25 OH)
  • Folate (serum)
  • Vitamin E
  • Vitamin A

Minerals

5

Minerals support bone strength, muscle function, nerve signalling, and energy production. They regulate vital processes such as blood pressure and immune responses. Key minerals like calcium, magnesium, and iron are obtained through diet and are crucial for preventing deficiencies and maintaining overall health.

  • Magnesium
  • Ferritin
  • Sodium
  • Chloride
  • Corrected Calcium

Haemoglobin A1c (HbA1c)

HbA1c provides an average reading of blood sugar levels over a period of 2-3 months. It is considered one of the best indicators of pre-diabetes and is also used by people with diabetes to monitor their levels. High blood glucose levels puts you more at risk of gaining weight, high blood pressure, heart disease and diabetes.

Thryoid Function

5

Thyroid hormones help to control the rate at which your body converts food into energy. Thyroid imbalance can lead to problems with weight, energy and mood. 

  • Thyroid Stimulating Hormone (TSH)
  • Thyroxine (T4, free direct)
  • Triiodothyronine (T3, free)
  • Thyroid Peroxidase Antibodies (TPO)
  • Thyroglobulin Antibodies (TG)

Sex Steroid Hormones

6

Sex steroid hormones are vital for numerous physiological processes within the body. Their roles extend far beyond reproduction influencing mood, bone health, cognitive function and metabolism.

  • Testosterone (total)
  • Progesterone
  • Oestradiol
  • Sex Hormone-Binding Globulin (SHBG)
  • Free Androgen Index (FAI)
  • Free Testosterone (calculated)

Pituitary hormones

3

FSH, LH, and prolactin, produced by the pituitary gland, are essential for reproductive health. Monitoring these hormones helps identify potential fertility issues and hormonal imbalances​.

  • Follicle Stimulating Hormone (FSH)
  • Luteinising Hormone (LH)
  • Prolactin

Cortisol

Cortisol, the "stress hormone," is released by the adrenal glands in response to stress. It regulates metabolism, maintains blood glucose levels, and modulates immune response. Elevated cortisol can result from anxiety, restricted diets, over-training, infection, trauma, or gland issues, leading to high blood pressure, high blood sugar, muscle weakness, and weight gain.

Full Blood Count (FBC)

3

A Full Blood Count (FBC) test measures various components of blood, in this test it includes red and white blood cell count as wells as haemoglobin. These tests helps identify conditions like anaemia, infections, and blood disorders.

  • Red Blood Cell (RBC)
  • White Blood Cell Count
  • Haemoglobin

SOMEWHAT LOW
Dr Thom Phillips

Your B12 is in the lower part of the healthy range. B12 works with folate and vitamin C to help the body make new proteins. We always try and promote a food first approach to addressing vitamin and mineral deficiencies so including B12 rich foods into your diet is a good place to start.

Your plan adapts to your body’s needs, considering hormonal changes, age, and treatments for a truly customised approach.

Invest in the most detailed, powerful health assessment available, because nothing is more valuable than understanding and taking control of your health.

What can the ultimate health check detect?

The Ultimate Health Check offers an in-depth analysis of your health by examining 47 essential biomarkers. Here’s a detailed look at what it could help detect:

  1. Nutritional Deficiencies: Identifies low levels of vital vitamins and minerals, including Vitamin D deficiency, Vitamin B12 deficiency, iron deficiency (anaemia), and folate deficiency, all of which can affect energy levels, immune function, and overall well-being.
  2. Hormonal Imbalances: Detects irregularities in hormones such as cortisol (stress hormone), testosterone, oestrogen, and progesterone. This can help identify conditions like polycystic ovary syndrome (PCOS), menopause-related hormonal shifts, and adrenal fatigue.
  3. Indicators of Heart Disease: Assesses cholesterol levels (HDL, LDL, total cholesterol), triglycerides, and markers like high-sensitivity C-reactive protein (hs-CRP) that indicate inflammation linked to heart disease. It can flag risks for atherosclerosis, hypertension, and coronary artery disease.
  4. Liver and Kidney Dysfunction: Measures enzymes like ALT, AST, and bilirubin to detect liver conditions such as fatty liver disease or hepatitis. It also checks kidney markers like creatinine and urea to identify early signs of chronic kidney disease or impaired kidney function.
  5. Thyroid Irregularities: Evaluate TSH, T3, and T4 levels to detect thyroid conditions such as hypothyroidism (underactive thyroid), hyperthyroidism (overactive thyroid), and Hashimoto’s thyroiditis.
  6. Immune System Weaknesses: Analyses markers like white blood cell count, CRP, and ferritin to uncover underlying infections, chronic inflammation, or autoimmune disorders like rheumatoid arthritis or lupus.

You should consult a healthcare professional if you have questions about your results.

Is the ultimate health check a finger prick test?

No, the ultimate health check requires a trained healthcare professional to draw a blood sample from a vein in your arm. You can choose to have this done in the comfort of your home or at one of our many partner clinics throughout the UK.

When will I get my results?

This test includes an omega 3:6 ratio, which means the turnaround time is slightly longer than our other tests. You’ll get your results within 15 days of your sample reaching our lab.

Will a doctor review my results?

Yes, a qualified member of our medical team will thoroughly review your results. You’ll receive personalised feedback with detailed insights into your report and recommendations for potential next steps. This commentary takes into account personal information from your profile, such as your gender, age, and BMI.

If you’d rather not receive the doctor’s feedback, you have the option to opt-out.

How secure is my data?

We take your data security seriously and use advanced measures to protect your information. All data handling complies with GDPR regulations, ensuring strict legal standards are met. Your information is only accessed when necessary to provide our services, for instance, our doctors can view your results solely during the review process, and their access is immediately revoked once the review is complete.

Important information regarding corrected calcium

Our laboratories have conducted stability validation for all biomarkers provided by Forth. Corrected Calcium has a shorter stability window than most markers, typically around 2 to 3 days. To ensure timely processing, Forth includes a Tracked 24 return envelope with all kits, allowing samples to reach the lab within 24 hours. In most cases, samples are returned within this stability period. If a sample arrives after this time frame, the corrected calcium result will not be provided.
