What's measured
71 biomarkers in this test
Every marker below is read against optimal ranges — not just the lab reference band — and explained by a clinician on your results call.
Full Blood Count
15 markersRed Blood Cell Count (RBC)
10¹²/LHow many red blood cells you have carrying oxygen around your body.
Why it matters
Low counts mean less oxygen reaching your tissues, which is felt as breathlessness and fatigue.
Haemoglobin (HGB)
g/LThe iron-containing protein in red cells that actually carries oxygen.
Why it matters
The defining measure of anaemia, and one of the most common explanations for unexplained tiredness.
Haematocrit (HCT)
%The proportion of your blood made up of red cells, by volume.
Why it matters
Read with haemoglobin to distinguish true anaemia from simple dehydration.
Mean Corpuscular Volume (MCV)
fLThe average size of your red blood cells.
Why it matters
Small cells point to iron deficiency; large cells point to B12 or folate. It tells us where to look next.
Mean Corpuscular Haemoglobin (MCH)
pgThe average amount of haemoglobin inside each red cell.
Why it matters
Supports MCV in separating the different causes of anaemia.
Mean Corpuscular Haemoglobin Concentration (MCHC)
g/LHow concentrated the haemoglobin is within each red cell.
Why it matters
Helps identify specific red-cell disorders that the other indices can miss.
Red Cell Distribution Width (RDW)
%How much your red blood cells vary in size.
Why it matters
Often the earliest abnormal marker in developing iron deficiency, before any other value shifts.
Platelets (PLT)
10⁹/LThe cell fragments that let your blood clot.
Why it matters
Too few risks bleeding, too many risks clotting — and either can flag a problem in the bone marrow.
Mean Platelet Volume (MPV)
fLThe average size of your platelets.
Why it matters
Larger platelets are younger and more active, giving a clue about how fast they are being produced.
Lymphocytes (LYM)
10⁹/LThe immune cells that handle viruses and long-term immunity.
Why it matters
Typically raised in viral infection and suppressed by chronic stress.
Monocytes (MON)
10⁹/LImmune cells that clear debris and support longer-running immune responses.
Why it matters
Persistently raised counts can point to chronic inflammation.
Neutrophils (NEU)
10⁹/LThe immune cells that respond first to bacterial infection.
Why it matters
High counts suggest bacterial infection or stress; very low counts leave you vulnerable to infection.
Eosinophils (EOS)
10⁹/LImmune cells involved in allergy and parasitic infection.
Why it matters
A raised count often points to underlying allergy, asthma or eczema.
Basophils (BAS)
10⁹/LThe rarest white cells, involved in allergic and inflammatory responses.
Why it matters
Rarely abnormal alone, but useful as part of the full immune picture.
Thyroid Function and Antibodies
5 markersFree T4
pmol/LThe unbound, available form of thyroxine — your thyroid's main circulating hormone.
Why it matters
Read with TSH, it separates a thyroid that is failing from a pituitary signalling problem.
Free T3
pmol/LThe active thyroid hormone your cells actually use to set metabolic rate.
Why it matters
Explains why some people feel hypothyroid despite normal TSH — conversion from T4 to T3 can be impaired.
Thyroid Stimulating Hormone (TSH)
mIU/LThe pituitary's signal telling your thyroid how much hormone to produce.
Why it matters
The most sensitive early marker of thyroid trouble. TSH shifts before T4 and T3 do, and before most people notice symptoms.
Thyroglobulin Antibodies (TG Ab)
IU/mLAntibodies against thyroglobulin, the protein your thyroid stores hormone in.
Why it matters
Measured alongside TPO to complete the autoimmune picture, particularly in Hashimoto's.
Thyroid Peroxidase Antibodies (TPO Ab)
IU/mLAntibodies against the enzyme your thyroid uses to make hormone.
Why it matters
Their presence predicts future thyroid failure, which is why we look even when TSH is still normal.
Micronutrients and Vitamins
8 markersActive Vitamin B12
pmol/LThe portion of B12 your cells can actually use.
Why it matters
More accurate than total B12, which can look normal while the usable fraction is low.
Total Vitamin B12
pmol/LThe total B12 in your blood, both active and bound forms.
Why it matters
A useful screen, though much of what it measures is bound and unavailable to your cells.
Vitamin D
nmol/LThe vitamin your skin makes from sunlight, essential for bone, muscle and immune function.
Why it matters
Deficiency is near-universal in northern Europe through winter, and among the easiest deficiencies to correct.
Vitamin B9 (Folate Serum)
nmol/LThe folate currently circulating in your blood.
Why it matters
Reflects recent intake rather than long-term stores.
Ferritin
µg/LYour body's iron store — the protein that holds iron until it is needed.
Why it matters
The first thing to fall when iron runs low, often long before haemoglobin drops. A common and very treatable cause of fatigue.
Iron
µmol/LThe iron currently circulating in your blood.
Why it matters
Fluctuates through the day and with recent meals, so it is read alongside ferritin and transferrin rather than alone.
Transferrin
g/LThe protein that transports iron through your bloodstream.
Why it matters
Rises when iron is scarce as your body tries to capture more, helping separate true deficiency from inflammation.
Zinc
µmol/LAn essential trace mineral used by hundreds of enzymes, immunity and wound healing.
Why it matters
Deficiency shows up as poor immunity, slow healing and taste changes, and is common in vegetarian diets.
Amino Acids
1 markerHomocysteine
µmol/LAn amino acid that rises when B12, folate or B6 are insufficient.
Why it matters
Raised levels are linked to cardiovascular and cognitive risk, and usually respond to correcting the underlying B-vitamin gap.
Diabetes
1 markerHbA1c
mmol/molYour average blood sugar over the past two to three months, measured on your red blood cells.
Why it matters
Unlike a single glucose reading, this cannot be gamed by fasting. It is the standard for diagnosing and tracking diabetes.
Hormones
12 markersOestradiol (Estrogen)
pmol/LThe main form of oestrogen, central to the menstrual cycle and bone health.
Why it matters
Interpreted against cycle timing in women; in men, raised levels can cause their own symptoms.
Luteinizing Hormone (LH)
IU/LThe pituitary hormone that triggers ovulation and testosterone production.
Why it matters
Its ratio to FSH is a central clue in diagnosing PCOS.
Follicle Stimulating Hormone (FSH)
IU/LThe pituitary hormone that drives egg and sperm production.
Why it matters
A key marker of ovarian reserve and the transition into menopause.
Sex Hormone Binding Globulin (SHBG)
nmol/LThe protein that binds sex hormones and controls how much is free.
Why it matters
Explains a normal total testosterone with low free testosterone, and shifts with insulin resistance and thyroid function.
Total Testosterone
nmol/LAll testosterone in your blood, both bound and unbound.
Why it matters
The standard first measurement, though much of it is bound and unavailable to your cells.
Free Testosterone
pmol/LThe unbound testosterone your body can actually use.
Why it matters
Often the more meaningful number — total testosterone can look normal while the usable fraction is low.
Testosterone : Free Testosterone Ratio
pmol/LThe unbound testosterone your body can actually use.
Why it matters
Often the more meaningful number — total testosterone can look normal while the usable fraction is low.
Testosterone : Cortisol Ratio
ratioThe balance between your main anabolic hormone and your main stress hormone.
Why it matters
A falling ratio is an early sign of overtraining or chronic stress, often before performance drops.
Prolactin
mIU/LThe pituitary hormone best known for milk production.
Why it matters
Raised levels disrupt periods, fertility and libido in both sexes, and are usually correctable.
Cortisol
nmol/LYour main stress hormone, following a daily rhythm.
Why it matters
Explains fatigue, weight change and poor sleep. Timing of the sample matters as much as the number.
Free Androgen Index (FAI)
ratioThe ratio of total testosterone to SHBG, estimating active androgen.
Why it matters
A key calculation in assessing PCOS and androgen excess in women.
DHEA Sulphate
µmol/LAn adrenal hormone that acts as a building block for sex hormones.
Why it matters
Falls steadily with age and gives a read on adrenal output.
Full Kidney Function
4 markersCreatinine
µmol/LA waste product from normal muscle activity, cleared by your kidneys.
Why it matters
The standard measure of kidney filtration, though it is also affected by muscle mass.
eGFR (CKD-EPI 2009 formula)
mL/min/1.73m²An estimate of how much blood your kidneys filter each minute.
Why it matters
The clearest single number for kidney function, and how kidney disease is staged.
Urea
mmol/LA waste product from protein breakdown, cleared by the kidneys.
Why it matters
Rises with dehydration and high protein intake as well as kidney problems, so it is read alongside creatinine.
Uric Acid
µmol/LA waste product from the breakdown of purines in food and cells.
Why it matters
High levels cause gout and are linked to high blood pressure and metabolic problems.
Full Liver Function
7 markersGlobulin Calculation
g/LThe protein fraction that includes your antibodies.
Why it matters
Raised levels can indicate chronic infection or inflammation; low levels suggest weakened immunity.
Albumin
g/LThe main protein your liver makes, holding fluid inside your blood vessels.
Why it matters
A good measure of longer-term liver function and nutritional state.
Total Protein
g/LAll the protein circulating in your blood.
Why it matters
Read with albumin to separate liver problems from immune or kidney causes.
Total Bilirubin
µmol/LAll bilirubin in your blood, both processed and unprocessed.
Why it matters
The standard screen for how well your liver is clearing this waste product.
Alanine AminoTransferase (ALT)
U/LA liver enzyme released into the blood when liver cells are stressed or damaged.
Why it matters
The most specific routine marker of liver strain — commonly raised by fatty liver, alcohol or medication.
Gamma-GlutamylTransferase (GGT)
U/LA liver enzyme particularly sensitive to alcohol and bile duct problems.
Why it matters
The most responsive marker to alcohol intake, and a useful check on liver recovery.
Alkaline Phosphatase (ALP)
U/LAn enzyme from the liver, bile ducts and bone.
Why it matters
Raised levels point either to a bile-flow problem or to active bone turnover.
Basic Cholesterol
6 markersLDL Cholesterol
mmol/LThe cholesterol carried by low-density lipoproteins, the particles that deposit cholesterol into artery walls.
Why it matters
LDL is the single most modifiable driver of heart disease. Lowering it years before symptoms is one of the most effective things you can do.
Non-HDL Cholesterol
mmol/LTotal cholesterol minus HDL — everything left that can contribute to plaque.
Why it matters
A better predictor of cardiovascular risk than LDL alone, because it captures every artery-damaging particle in one number.
HDL Cholesterol
mmol/LThe cholesterol carried by high-density lipoproteins, which transport it away from the arteries back to the liver.
Why it matters
Higher is generally protective. A low HDL alongside high triglycerides often points to insulin resistance rather than diet alone.
Total Cholesterol
mmol/LThe total amount of cholesterol carried in your blood, combining the LDL, HDL and other fractions.
Why it matters
On its own it is a blunt number — the split between LDL and HDL matters far more, which is why we always read it alongside them.
Total Cholesterol / HDL Ratio
ratioYour total cholesterol divided by your HDL, expressing the balance between the two.
Why it matters
A cleaner risk signal than either number alone, and one of the values most responsive to changes in diet and activity.
Triglycerides
mmol/LThe main form of fat circulating in your blood, mostly from what you eat and what your liver produces.
Why it matters
Raised triglycerides are an early sign that your body is struggling to handle sugar and refined carbohydrate — often before glucose looks abnormal.
Advanced Cholesterol
4 markersApolipoprotein A1 (Apo A1)
g/LThe main protein on HDL particles, reflecting how well your body clears cholesterol from artery walls.
Why it matters
A low ApoA1 suggests your protective pathway is weak even when HDL cholesterol looks acceptable.
Apolipoprotein B (Apo B)
g/LA direct count of the atherogenic particles in your blood — every LDL and related particle carries exactly one ApoB.
Why it matters
Where LDL estimates the cholesterol inside particles, ApoB counts the particles themselves. It is the more accurate predictor of heart disease risk.
Apo B : Apo A1 Ratio
ratioThe balance between artery-damaging and artery-protecting particles.
Why it matters
One of the strongest single predictors of heart attack risk in large international studies.
Lipoprotein(a) [Lp(a)]
nmol/LAn inherited, sticky form of LDL that raises cardiovascular risk independently of diet or lifestyle.
Why it matters
Largely genetic and stable for life, so it only needs measuring once — but knowing it changes how aggressively other risks should be managed.
Inflammation
2 markersC-Reactive Protein (CRP)
mg/LA protein your liver releases in response to inflammation anywhere in the body.
Why it matters
Sensitive but non-specific: it confirms inflammation is present without saying where. Persistently mild elevation is linked to cardiovascular risk.
Creatine Kinase (CK)
U/LAn enzyme released when muscle is broken down.
Why it matters
Rises after hard exercise, and flags muscle side effects from cholesterol medication.
Advanced Electrolytes
6 markersMagnesium
mmol/LA mineral involved in muscle function, nerve signalling and energy production.
Why it matters
Low magnesium contributes to cramps, palpitations and poor sleep, and often accompanies high sugar intake.
Potassium
mmol/LAn electrolyte essential for heart rhythm and muscle function.
Why it matters
Both high and low levels affect the heart directly, which makes it one of the more urgent results.
Total Calcium
mmol/LAll calcium in your blood, both bound to protein and free.
Why it matters
The standard screen, interpreted against albumin since much of it travels bound to protein.
Corrected Calcium
mmol/LYour calcium adjusted for albumin level.
Why it matters
A truer reading than total calcium when protein levels are abnormal.
Sodium
mmol/LThe main electrolyte controlling fluid balance in your body.
Why it matters
Abnormal levels affect blood pressure and brain function, and can flag kidney or hormonal problems.
Chloride
mmol/LAn electrolyte that works with sodium to maintain fluid and acid balance.
Why it matters
Helps identify the cause when acid-base balance is disturbed.
