Haemoglobin
The oxygen-carrying part of your red blood cells.
Why it matters
Low levels are linked to feeling tired or short of breath.
This comprehensive blood analysis evaluates the cellular composition of your blood, identifying abnormalities in red cells, white cells, and platelets. Essential for diagnosing conditions such as anaemia, infection, and clotting disorders, an FBC provides critical insights into your haematological health and serves as a foundational screening tool in clinical assessment.
Sample requirements
Collected by our partnered phlebotomist in your booked clinic appointment. Phlebotomy fee included in the price.
The oxygen-carrying part of your red blood cells.
Low levels are linked to feeling tired or short of breath.
The proportion of your blood made up of red cells.
Gives a quick snapshot of how oxygen-rich your blood is.
The average amount of haemoglobin in each red blood cell.
Helps show whether your red cells are well-stocked with oxygen-carrying protein.
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.
The number of red cells in your blood.
Red cells carry oxygen — too few or too many can both be a sign something's off.
A type of white blood cell.
Linked to allergic responses and how your body deals with irritants.
Immune-system white blood cells.
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.
