Test Overview
What is the Tiredness & Fatigue Blood Test?
Our Tiredness & Fatigue Blood Test is designed to help identify common underlying causes of ongoing tiredness by assessing key vitamins, iron levels, and blood health markers.
This test is ideal if you are experiencing:
- Persistent tiredness or low energy
- Feeling run down despite rest
- Weakness or lack of motivation
- Unexplained fatigue affecting daily life
It’s also suitable if you want to understand the root cause of your symptoms and take a proactive approach to improving your wellbeing.
Fatigue can be caused by a range of underlying factors, many of which are not immediately obvious.
This test focuses on some of the most common causes, including:
- Iron deficiency (anaemia)
- Vitamin deficiencies (such as Vitamin D)
- Blood health and oxygen transport issues
By assessing these markers together, this test helps provide a clearer understanding of why you may be feeling tired and whether further investigation or support may be needed.
This test measures 18 biomarkers across 3 categories:
- Blood Cells (15 biomarkers)
- Iron Profile (2 biomarkers)
- Vitamins (1 biomarker)
These markers provide a focused assessment of the most common contributors to fatigue.
- You must be 18 years or over to take this test
- No fasting is required
What biomarkers do we test?
- Blood Cells Panel: Includes red blood cells, white blood cells, haemoglobin, platelets and indices to assess overall blood health.
- Iron: Iron is essential for producing haemoglobin, allowing oxygen transport around the body.
- Ferritin: Ferritin reflects iron stores in the body. Low levels may indicate deficiency.
- Vitamin D: Essential for bone health, muscle function and immune system support.
