This panel can help you: gain a full picture of your health, including hormones and nutrition; detect early signs of heart, liver, kidney, or metabolic conditions; assess prostate health with a detailed PSA screen; monitor lifestyle changes, exercise, or medical treatments; and provide reassurance with a wide-ranging check-up in a single blood test.

1. Blood cell health: Haemoglobin and red blood cells measure oxygen-carrying capacity, and low levels may suggest anaemia. White blood cells (WBCs) help fight infection. Platelets are essential for clotting. Extra red cell markers (MCV, MCH, MCHC, RDW, HCT and MPV) provide more detailed insight into blood balance. 2. Heart and circulation: Your cholesterol profile (total, HDL, LDL and ratios) checks the balance of “good” and “bad” cholesterol. Triglycerides are fats in the blood linked to heart risk. High-sensitivity CRP (hs-CRP) is a marker of inflammation that can affect heart health. Creatine kinase (CK) can rise with muscle strain or heart injury. 3. Blood sugar and metabolic health: HbA1c shows your average blood sugar over the last three months. Uric acid can be raised in gout and some metabolic conditions. 4. Kidney health: Creatinine and urea are waste products filtered by the kidneys. Electrolytes (sodium, potassium, chloride, magnesium and phosphate) help maintain fluid balance, heart rhythm, and muscle and nerve function. 5. Liver function: Liver enzymes (ALT, AST, gamma-GT and ALP) can rise when the liver is stressed or damaged. Bilirubin is a waste product processed by the liver, and raised levels may suggest liver or bile duct issues. Albumin and globulin are proteins made by the liver and can reflect nutrition and overall liver function. Total protein shows overall protein balance in the blood. 6. Prostate health: Prostate specific antigen (PSA) is a key marker for prostate health. Free PSA and the PSA ratio add further detail to prostate risk assessment. 7. Male hormone health: Testosterone supports energy, strength, libido, and mood. Free T3, free T4 and TSH are thyroid hormones that regulate metabolism and energy. 8. Nutritional and vitamin status: Vitamin D supports bone, muscle and immune health. Vitamin B12 and folate (B9) are essential for red blood cells, energy and nerve health. Iron studies (iron, ferritin, transferrin and iron binding capacity) assess stored and circulating iron levels. Calcium, phosphate and magnesium are key minerals for bone and muscle health.

Fasting guidance: Most of these tests can be done at any time of day. For the most accurate results, we recommend attending in the morning after fasting (no food or drink except water) for 8 to 10 hours. This is particularly important for cholesterol, glucose and iron studies. If fasting is not practical, you can still attend, and your results will still provide valuable information.

Understanding your sports performance blood test. This advanced blood test is designed for athletes and active individuals who want to understand how their body is performing, recovering, and adapting to training. It covers energy metabolism, muscle recovery, cardiovascular risk, hormone balance, and key nutrients that support strength and endurance. Why choose this test? This panel can help you: detect nutrient deficiencies or imbalances that limit performance; identify signs of overtraining, inflammation, or metabolic stress; track hormone and iron status for strength, endurance, and recovery; and personalise your training, nutrition, and recovery strategies.

1. Energy and metabolic health: Glucose and HbA1c show how your body manages energy before, during, and after exercise. Ketones may indicate fat adaptation or under-fuelling. Thyroid hormones (TSH, FT3 and FT4) regulate metabolism, energy, and recovery. Cortisol and DHEA-S are stress and recovery hormones, and imbalances may signal overtraining. 2. Muscle function and recovery: Creatine kinase (CK), CK-MB and myoglobin are markers of muscle stress or damage. Persistently high levels can suggest poor recovery. Total antioxidant status indicates resilience against oxidative stress caused by intense training. Uric acid can rise with heavy exertion or dehydration. 3. Cardiovascular and lipid health: Cholesterol (total, HDL, LDL, ratios and triglycerides) provides core markers of heart health. Apolipoproteins (A1, B and the ApoB/A1 ratio) give a more detailed view of cardiovascular risk. A cardiovascular risk score combines lipid and inflammation markers for overall heart risk. 4. Oxygen transport and iron status: A full blood count (FBC) measures haemoglobin, red cells, white cells, and platelets. Ferritin, iron, TIBC, transferrin and transferrin saturation show iron stores and transport, which are essential for endurance. 5. Hormonal balance: Testosterone and the free androgen index are key for muscle repair, power, and recovery. SHBG (sex hormone binding globulin) affects how much testosterone is available. LH (luteinising hormone) can help screen for overtraining or low energy availability, including RED-S. 6. Inflammation and organ stress: C-reactive protein (CRP) can rise with systemic inflammation. Liver enzymes (ALT, AST, GGT and ALP) may rise with intense training, and persistently abnormal results may suggest organ stress. Bilirubin may be raised in endurance athletes due to increased red cell turnover. 7. Electrolytes and hydration: Sodium, potassium, chloride, magnesium, phosphate, calcium and urea support hydration, nerve signalling, and muscle contraction. 8. Key nutrients: Vitamin D supports immunity, bone strength and muscle function. Vitamin B12 and folate are essential for energy and red blood cell production. Albumin is a protein marker linked to nutrition and recovery. Why athletes use this test: spot energy-limiting factors (such as iron deficiency or low testosterone); optimise nutrition and training for peak performance; monitor recovery and reduce the risk of overtraining; and gain insights tailored to strength, endurance, or competitive goals.

Preparation: fasting is required for 8 to 10 hours (water only) for accurate glucose and lipid results. Avoid intense exercise for 48 hours before testing to prevent artificially high muscle damage markers.

Why it matters
An underactive thyroid can cause tiredness, weight gain, and feeling cold.
An overactive thyroid can cause anxiety, weight loss, and a fast heartbeat.

Reproductive and Sex Hormones

For women
FSH and LH – important for ovulation, the menstrual cycle, and menopause.
Oestradiol and progesterone – help regulate cycles, fertility, and mood balance.

Total iron-binding capacity (TIBC) – shows how much capacity your blood has to carry iron.
High levels may indicate iron deficiency.
Low levels may suggest adequate iron stores or chronic disease.
Transferrin and transferrin saturation – transferrin carries iron, and saturation shows how much is bound.
Low transferrin saturation (often below 20%) suggests iron deficiency.
High transferrin saturation (often above 45%) may suggest iron overload.

Who should take this test?
If you feel tired, dizzy, or pale (possible anaemia)
If you have heavy periods or are pregnant
If you have joint pain, fatigue, or a family history of haemochromatosis
If you follow a vegetarian or vegan diet and want to monitor your iron intake

For the most accurate results, fast for 8–12 hours before your test (no food or drink except water).

Check how well your kidneys are filtering waste from the blood
Assess early signs of kidney stress, which may not cause symptoms at first
Review your body’s mineral and electrolyte balance, which supports heart, muscle, and nerve function
Support monitoring if you have risk factors such as high blood pressure, diabetes, or a family history of kidney disease

Key kidney function tests
Creatinine – a waste product produced by normal muscle activity. Higher levels may suggest your kidneys are not filtering as effectively as they should.

eGFR (estimated glomerular filtration rate) – an estimate of how well your kidneys are filtering. You can think of it like a “kidney battery percentage”:
90–100 = normal kidney function
60–89 = mild reduction
30–59 = moderate reduction
Below 30 = significant reduction

Urea – a waste product produced when the body breaks down protein. Higher levels may suggest dehydration or kidney stress.

Mineral and electrolyte balance tests
Sodium and potassium – help regulate fluid balance and nerve and muscle function. Imbalances can affect blood pressure and heart rhythm.

Calcium and phosphate – important for bone health. The kidneys help activate vitamin D, which supports calcium absorption.

Magnesium – supports nerve and muscle function and overall energy production. It is often overlooked, but it plays an important role.

No fasting is required for this test. For best accuracy, stay well hydrated and avoid heavy exercise immediately before your appointment.

Checks how well your liver is working by measuring key enzymes, proteins, and substances in your blood. It can help assess liver stress or damage, and how effectively the liver is processing waste and producing proteins. It may be especially important if you:
Feel unusually tired or nauseous
Notice yellowing of the skin or eyes (jaundice)
Have abdominal pain or swelling
Drink alcohol regularly
Take medications that may affect the liver
Have diabetes or are overweight

Alkaline phosphatase (ALP)
Alanine aminotransferase (ALT)
Aspartate aminotransferase (AST)
Gamma GT (GGT)
Total bilirubin
Albumin
Ferritin

You do not usually need to fast for this test. Temporary illnesses can affect results, and many people with early liver changes may not have symptoms.

Measures the fats (lipids) in your blood to assess your heart and metabolic health. It helps identify risk factors for cardiovascular disease, stroke, and other related conditions. It can also be used to monitor cholesterol-lowering treatment and screen for inherited cholesterol conditions.

Total cholesterol – the overall amount of cholesterol in your blood (both “good” and “bad”). Higher levels may increase heart disease risk.
LDL cholesterol (“bad” cholesterol) – can build up in arteries and contribute to blockages; lower levels are generally better for heart health.
HDL cholesterol (“good” cholesterol) – helps remove excess cholesterol from blood vessels; higher levels are generally protective.
Triglycerides – a type of fat that circulates in the blood; higher levels may increase cardiovascular risk.
Total cholesterol/HDL ratio – compares total cholesterol to protective HDL; a lower ratio is generally linked to lower risk.
Cholesterol ratio – provides an additional indicator of overall cardiovascular risk.

Fast for 9–12 hours before your test (water is allowed). Avoid high-fat meals the day before for the most accurate results.

Investigate possible causes of muscle pain, joint stiffness, or unexplained fatigue. It looks at inflammation and autoimmune markers and also includes liver, kidney, bone/mineral, and iron status tests, which can contribute to muscle or joint symptoms. It may be helpful if you have persistent joint stiffness, muscle weakness, swollen joints, or ongoing fatigue, or if you are being assessed for conditions such as rheumatoid arthritis or gout.

For the most accurate results, attend in the morning after fasting (no food or drink except water) for 8–10 hours. This is especially important for glucose, insulin, and cholesterol testing.

Measures two key hormones involved in your stress response. Cortisol reflects how your body responds to stress and follows a natural daily rhythm, while DHEA-S is another adrenal hormone linked to energy, mood, and resilience. It may be helpful if you are experiencing ongoing fatigue, stress-related symptoms, sleep disruption, unexplained weight changes, or if you are monitoring adrenal health.

Cortisol
DHEA-S (dehydroepiandrosterone sulfate)

No special preparation is usually required. Cortisol varies by time of day, so testing time may be important for interpretation.

Evaluates thyroid function by measuring key thyroid hormones and antibodies. It can help detect an underactive thyroid (hypothyroidism), an overactive thyroid (hyperthyroidism), and autoimmune thyroid disease. It may be useful if you have symptoms such as fatigue, weight changes, mood changes, hair thinning, or if you are monitoring known thyroid issues or treatment.

Assess deficiencies that may contribute to fatigue, nerve issues, anaemia, and metabolic dysfunction
Investigate unexplained fatigue
Investigate neurological symptoms such as tingling or memory fog
Investigate anaemia
Investigate skin or mouth lesions
Support monitoring in malnutrition (including alcoholism or vegan diets)

Vitamin B1 (thiamine) – supports energy metabolism and nerve function; deficiency can cause beriberi (fatigue, nerve damage), commonly linked to alcohol misuse or malnutrition
Vitamin B2 (riboflavin) – supports red blood cell production and skin and eye health; deficiency can cause cracked lips, sore throat, and light sensitivity
Vitamin B3 (niacin/nicotinamide) – helps maintain cholesterol levels and skin health; deficiency can cause pellagra (diarrhoea, dementia, dermatitis)
Vitamin B6 (pyridoxine) – supports brain health, haemoglobin synthesis, and hormone regulation; deficiency can cause anaemia, depression, and weakened immunity
Active B12 (cobalamin) – vital for nerves and DNA synthesis; deficiency can cause anaemia and tingling
Red cell folate (vitamin B9) – supports cell division; low levels increase neural tube defect risk in pregnancy

No special preparation is usually required.

Evaluate toxic metal exposure and essential mineral imbalances that can impact neurological health, organ function, and metabolic processes
Support assessment where occupational exposure is a concern
Support assessment where neurological symptoms may be linked to heavy metals (for example, tremors associated with lead or mercury)

Toxic heavy metals
Lead (blood) – toxicity risks include neurodevelopmental delays (children), anaemia, and kidney damage; potential sources include old paint, contaminated water, and industrial exposure
Mercury (blood) – toxicity risks include nerve damage and memory issues (methylmercury from fish); potential sources include seafood, dental amalgams, and industrial pollution
Aluminium (blood) – toxicity risks include bone and brain accumulation (linked to dialysis patients); potential sources include cookware, antacids, and vaccines
Chromium (blood) – toxicity risks include kidney and liver damage (hexavalent Cr⁶⁺, industrial exposure); trivalent Cr³⁺ supports glucose metabolism
Manganese (blood) – toxicity risks include Parkinson-like symptoms (miners/welders); supports bone and antioxidant enzyme function

Essential minerals (red cell analysis)
Red cell magnesium – low levels may be linked to muscle cramps and arrhythmias; high levels are rare (kidney dysfunction)
Red cell calcium imbalances may be linked to parathyroid disorders
Red cell zinc deficiency may be linked to weak immunity and slow wound healing
Red cell copper – imbalance may be linked to Wilson’s disease (excess) or Menkes syndrome (deficit)
Red cell selenium deficiency may be linked to thyroid dysfunction and cardiomyopathy

No special preparation is usually required

Identify foods that may be causing immediate allergic reactions
Explore potential delayed food intolerances linked to bloating, fatigue, or skin or joint issues
Guide elimination diets or referral for allergy specialist input
Gain reassurance when food reactions are unclear

Almond, peach, apple, peanut, carrot, potato, casein (milk protein), rye flour, celery, sesame seed, cod fish, shrimp, egg white, soya, egg yolk, tomato, hazelnut, walnut, milk, wheat flour

IgE Food Allergy Testing (FP20)
Measures IgE antibodies linked to true allergies
Reaction time is immediate (minutes to a few hours)
Symptoms can include hives, swelling, wheeze or asthma, vomiting, and anaphylaxis
Best for sudden, repeatable reactions after eating a food
Helps confirm true food allergy, often alongside specialist review

IgG Food Intolerance Testing (FG20)
Measures IgG antibodies linked to delayed reactions
Reaction time is delayed (hours to days)
Symptoms can include bloating, digestive discomfort, headaches, fatigue, and skin or joint flare-ups
Important to know: IgG results show exposure, not necessarily intolerance. Raised results do not prove an allergy, but may help guide a structured elimination and reintroduction plan.

Which test should I choose?
Choose IgE (FP20) if you suspect a true allergy with rapid, obvious symptoms
Consider IgG (FG20) if you have ongoing, delayed symptoms without a clear trigger
Some people choose to combine both for a fuller picture

No fasting is required.

Identify foods that may be triggering immediate allergic reactions
Explore potential delayed food sensitivities linked to symptoms such as bloating or headaches
Support decisions around avoidance, elimination diets, or referral for specialist assessment
Provide clearer direction when food-related symptoms are difficult to interpret

IgE testing (FP34) – checks IgE antibodies linked to immediate allergies. Reactions can occur within minutes to hours and may be severe, including anaphylaxis. Symptoms can include hives, swelling, and breathing difficulties. Results are often used alongside skin prick testing.

IgG testing (FG34) – measures IgG antibodies linked to delayed food sensitivities. Symptoms may appear hours to days later, such as bloating or headaches. Important note: raised IgG levels may reflect frequent exposure to a food and do not necessarily confirm intolerance.

Foods included in this panel
