Heart and blood vessels
14 in CoreThe particles and proteins behind long-term heart and artery health, including ApoB and Lipoprotein(a).
Apolipoprotein BA protein carried by every particle that can deposit cholesterol in artery walls, so it gives a direct count of your artery-clogging particles.Lipoprotein(a)An inherited, LDL-like particle that raises the risk of heart attack, stroke and aortic valve narrowing. One test usually covers life.Blood pressure, systolicThe top number in a blood pressure reading: the pressure in your arteries at the moment your heart beats and pushes blood out, measured in millimetres of mercury (mmHg). Our nurse takes it with you seated and rested, before your draw.Blood pressure, diastolicThe bottom number in a blood pressure reading: the pressure in your arteries while your heart relaxes between beats, in mmHg. Our nurse takes it at the same time as the top number, before your draw.TriglyceridesThe main type of fat in your blood, used for energy. Levels reflect diet, alcohol, weight and how your body handles sugar and fat.HomocysteineAn amino acid made when your body processes protein. It is cleared with the help of folate, B12 and B6, so a high level often points to low B vitamins.HDL cholesterolThe cholesterol carried in HDL particles, which take surplus cholesterol back to the liver. Higher levels usually go with better metabolic health.Total cholesterolAll the cholesterol in your blood, carried in LDL, HDL and other particles. Its parts tell you more than the total.Apolipoprotein A-1Protective particles.8 more calculated by Ayu from these results, plus 9 coming soon
LDL cholesterolThe cholesterol carried in LDL particles, the main type that builds up in artery walls. Ayu calculates it from your other lipid results.Non-HDL cholesterolAll the cholesterol in your blood except HDL: the cholesterol in every particle that can build plaque.

7 in CoreHow your body handles sugar and insulin, both day to day and over the past few months.
HbA1cYour average blood sugar over the past two to three months, measured as the share of haemoglobin with sugar attached.Fasting insulinThe hormone that moves sugar from your blood into your cells. A fasting level shows how hard your body works to keep blood sugar normal.Fasting glucoseThe amount of sugar in your blood after an overnight fast: a snapshot of how well your body controls blood sugar.Uric acidA waste product from the breakdown of purines, cleared by the kidneys. High levels can cause gout and kidney stones.WaistThe measurement around your middle, taken by our nurse at every draw, in centimetres.WeightYour weight, taken by our nurse at every draw, in kilograms.3 more calculated by Ayu from these results, plus 6 coming soon
HOMA-IR (insulin resistance)A score combining fasting glucose and fasting insulin to estimate insulin resistance: how strongly your body resists its own insulin.Waist-to-height ratioYour waist measurement divided by your height, both in the same units. The nurse measures your waist at every draw, so this updates each time.Body mass indexCalculated from the nurse's measurements.Estimated average glucoseCalculated insulin and sugar indices.HOMA-B (beta-cell function)Calculated insulin and sugar indices.QUICKI (insulin sensitivity)Calculated insulin and sugar indices.Triglyceride-glucose indexCalculated insulin and sugar indices.Uric acid-to-HDL ratioCalculated kidney indices.METS-IRCalculated insulin and sugar indices.Kidneys and urine

It is used to estimate kidney filtering (eGFR).Urea (BUN)A waste product made when your liver breaks down protein, cleared by the kidneys. It also reflects diet and hydration.Bicarbonate (total CO2)The amount of bicarbonate in your blood, reported by many labs as total CO2. Bicarbonate is the body's main buffer against acid.CalciumThe total amount of calcium in your blood: the free (ionised) part and the part carried on proteins such as albumin.ChlorideThe amount of chloride, a salt that works with sodium and bicarbonate to balance fluids and acid, in your blood.MagnesiumThe amount of magnesium, a mineral needed for muscles, nerves and a steady heart rhythm, in your blood.PotassiumThe amount of potassium, a mineral your heart, nerves and muscles depend on, in your blood.SodiumThe amount of sodium in your blood, which mainly reflects your body's water balance.Urine albumin (microalbumin)The amount of albumin, a blood protein, in a sample of your urine. It used to be called microalbumin.Urine creatinineThe amount of creatinine, a muscle waste product, in a sample of your urine.Urine amorphous sedimentUrinalysis.Urine appearanceUrinalysis.Urine bacteriaUrinalysis.Urine bilirubinUrinalysis.Urine bloodUrinalysis.Urine castsUrinalysis.Urine colourUrinalysis.Urine crystalsUrinalysis.Urine epithelial cellsUrinalysis.Urine glucoseUrinalysis.Urine ketonesUrinalysis.Urine leukocyte esteraseUrinalysis.Urine nitriteUrinalysis.Urine pHUrinalysis.Urine proteinUrinalysis.Urine red cellsUrinalysis.Urine specific gravityUrinalysis.Urine urobilinogenUrinalysis.Urine white cellsUrinalysis.Urine yeastUrinalysis.Cystatin CA small protein made at a steady rate by almost every cell and cleared by the kidneys, so a higher level suggests they are filtering less.Parathyroid hormoneParathyroid hormone, made by four small glands in the neck. It keeps blood calcium steady.PhosphateThe amount of phosphate, a mineral found in bone and in every cell, in your blood.2 more calculated by Ayu from these results, plus 2 coming soon

It is reported in mL/min per 1.73 m² of body surface.Liver
10 in CoreEnzymes and proteins that show how your liver is working, with a fibrosis panel in Performance.
ALTAn enzyme found mainly in liver cells. When liver cells are stressed or damaged, more ALT leaks into the blood.GGTA liver and bile-duct enzyme that rises with alcohol, fatty liver and bile-flow problems. Higher levels also track heart and metabolic risk.ASTAn enzyme found in the liver, muscles and heart. It leaks into the blood when those cells are stressed.AlbuminThe main protein in your blood, made by the liver. It holds fluid in your blood vessels and carries hormones, medicines and nutrients.Alkaline phosphataseAn enzyme made mainly in the liver and bones. It rises when bile flow slows or bone turnover speeds up.Direct bilirubinThe part of bilirubin the liver has already processed for removal in bile. It rises when bile cannot drain properly.Total bilirubinA yellow pigment made when old red blood cells are broken down, then processed by the liver and cleared in bile.Total proteinThe combined amount of albumin and globulins, including antibodies, in your blood.Collagen IVLiver fibrosis panel.Hyaluronic acidLiver fibrosis panel.LamininLiver fibrosis panel.Procollagen III N-terminal peptideLiver fibrosis panel.3 more calculated by Ayu from these results, plus 4 coming soon

6 in CoreIron stores, vitamins and minerals your body relies on.
FerritinThe protein that stores iron. Your blood level reflects your iron reserves, but it also rises with inflammation.Vitamin DMeasures 25-hydroxyvitamin D, the storage form your skin makes in sunlight. It is needed for calcium balance and healthy bones and muscles.IronThe amount of iron travelling in your blood, bound to its carrier transferrin, at the moment of the draw.Total iron binding capacityA measure of how much iron your blood's carrier protein, transferrin, could hold if it were full.ZincThe amount of zinc, a trace mineral used by hundreds of enzymes and by your immune system, in your blood.CopperThe amount of copper in your blood.

9 in CoreRed cells, white cells and platelets: the full count.
HaemoglobinThe iron-containing protein in red blood cells that carries oxygen around your body. It is the main test for anaemia.MCV (red cell size)The average size of your red blood cells. It helps show why anaemia happens and can point to a thalassaemia trait.MPV (platelet size)The average size of your platelets, the small cell fragments that help your blood clot.PlateletsTiny cell fragments that help your blood clot. The count shows whether you have enough, without too many.RDW (red cell width)How much your red blood cells vary in size. A higher value is linked with nutrient shortages and poorer long-term health.Red blood cellsThe number of red blood cells in a set volume of blood. Read with haemoglobin and MCV, it helps spot anaemia and thalassaemia traits.Blood group ABOYour ABO blood group: A, B, AB or O, set by the markers your red blood cells carry on their surface. It is inherited and measured once.Blood group RhYour Rh (rhesus) type: positive if your red cells carry the RhD marker, negative if they do not.

About the tests.
What does “calculated by Ayu” mean?
Some markers, like insulin resistance or the ratio of two cholesterol measures, come from combining results we already measure. Ayu works them out for you, so they add insight without another tube.
Why are some markers measured only once?
A few markers, like Lipoprotein(a) and your blood group, barely change over a lifetime. We measure them on your first draw and keep the result.
Do I need to fast?
Yes. Stop eating 10 to 12 hours before your visit. Water is fine.
Can I add a single test?
Not yet. Each panel is designed as a whole, so the results can be read in context with one another.
