Haemoglobin
The oxygen-carrying part of your red blood cells.
Why it matters
Low levels are linked to feeling tired or short of breath.
Discover your nutritional foundation with our comprehensive Nutritional Health panel. Meticulously designed by our in-house expert nutritionist, this assessment evaluates essential markers of your current nutritional status whilst identifying underlying factors that may contribute to or indicate suboptimal nutritional outcomes. Gain actionable insights into your micronutrient levels, metabolic indicators, and nutritional deficiencies to inform targeted dietary interventions and optimise your health trajectory.

How concentrated the haemoglobin is in your red blood cells.
Another angle on red blood cell quality, useful when looking at iron status.
The average size of your red blood cells.
Cell size can hint at iron, B12 or folate levels.

Shows how your body is responding to infections or viruses.
A white blood cell linked to allergies and parasites.
Higher levels can be a sign of allergies or other immune activity.
A clean-up white blood cell.
Gives insight into longer-running immune activity.
Your front-line infection-fighting white blood cells.
Often higher when your body is fighting something off.
The total count of immune cells in your blood.
A general marker of how active your immune system is.
Tiny cells that help your blood clot.
Low or high counts can be a sign your clotting balance is off.

The total amount of cholesterol in your blood.
A long-standing marker for heart and circulation health.
The 'less helpful' type of cholesterol.
Higher levels are linked to a greater chance of furred-up arteries over time.
The 'helpful' type of cholesterol.
Higher levels are generally linked to better heart health.
Total cholesterol compared with HDL.
A simple ratio that gives a clearer picture than total cholesterol alone.
Fats circulating in your blood.
Linked to diet, weight and heart health — often respond well to lifestyle tweaks.
Your body's iron stores.
Low levels can leave you feeling tired; very high levels can be a sign of inflammation or iron overload.
How much iron your blood can carry.
Helps put your iron level in context.
The protein that ferries iron around your body.
Adds detail to the iron-status picture.
How much of your transferrin is actually carrying iron.
A useful marker for both low iron and iron overload.
A liver health marker.
Higher levels can be a sign your liver is under stress, often linked to diet, alcohol, or fatty liver.
A marker linked to both liver and bone health.
Levels can shift when the liver is under strain or when bones are remodelling more than usual.
Another liver health marker.
Read alongside ALT, it gives extra insight into how your liver and muscles are coping.
A liver marker (often called GGT).
Often raised by alcohol or fatty liver — a useful check-in on lifestyle impact.
A waste product the liver clears from your blood.
Higher levels can be a sign your liver isn't clearing things as efficiently as usual.
Your blood sugar level at the moment of testing.
A snapshot of how your body is handling sugar right now.
Your average blood sugar over the last few months.
Useful for understanding how your body handles sugar over time.
The hormone that helps move sugar from blood into cells.
Gives insight into how hard your body is working to keep sugar in check.
An immune marker linked to gluten reactions.
Higher levels can be a sign your body is reacting to gluten.
An enzyme made by the pancreas.
Levels can shift if the pancreas is under stress.
The hormone that tells your thyroid how hard to work.
A first-line marker for thyroid balance.
The active form of one of your main thyroid hormones (T4).
Adds detail beyond TSH for a fuller thyroid picture.
The active form of your other main thyroid hormone (T3).
Helps show how well your thyroid signal is being used.
An immune marker linked to the thyroid.
Can be a sign your immune system is reacting to your thyroid.
Another immune marker linked to the thyroid.
Often raised when the immune system is reacting to thyroid tissue.
