What can I expect from Tiredness/Fatigue Profile?

This test is designed to discover clues in your blood as to why you may be feeling unusually tired or fatigued. 

It will give you information on on several common things that doctors look for in blood tests that may give physical reasons for tiredness. It includes a full blood count and tests for vitamin D, inflammation, iron levels including ferritin and thyroid function tests.

Analysis of 9 essential biomarkers including: 

  • Full Blood Count
  • Iron levels 
  • Ferritin
  • Transferrin
  • Vitamin D
  • Thyroid Stimulating Hormone (TSH) 
  • Free T4 (Throxine)

Due to the inclusion of a full blood count this test requires a phlebotomy sample which can be given at any of our 100+ nationwide partner locations.

What gets tested?

Full Blood Count (20 health indicators)

A full blood count (FBC) is a common blood test that gives a snapshot of your general health. It measures different types of cells in your blood, such as red blood cells, which carry oxygen; white blood cells, which fight infection; and platelets, which help blood to clot. This test can help diagnose conditions like anemia, infections, and even effects of chemotherapy. It also assists doctors in monitoring overall health and the impact of ongoing treatments, ensuring that any significant changes are noted and addressed promptly.

Iron Studies (5 health indicators)

Iron studies are a set of blood tests used to measure the amount of iron carried in the blood and stored in the bodies tissues. Iron deficiency can be the cause of a wide range of symptoms such as fatigue, chest pains and a shortness of breath. 

Thyroid (2 health indicators)

Thyroid disorders are common but often remain undiagnosed. If your thyroid isn't functioning properly, it can cause tiredness, mood problems and weight issues. 

Vitamins (1 health indicators)

Vitamins are a group of substances that our bodies need for normal cell function, growth and development. Vitamin deficiencies can be the cause of a wide range of common symptoms and conditions.

How do I read my results?

Laboratory results are provided with reference ranges which are based on the normal test results of a large group of healthy people from the same age group and gender as yourself.

Sometimes, healthy people get results outside the reference range, while people with health problems can have results in the normal range. If your results fall outside the reference range, or if you have symptoms despite a normal result, you may require more testing or wish to discuss the result with your GP.

For simplicity, we provided your results graphically, so they are easy to understand. Any result flagged amber is outside of the standard range. Normal results are in green.

If you see ‘invalid result’ on any of your report pages, it’s nothing to worry about. Please call our Customer Service team on 020 7183 3718 and if required we will be able to arrange another blood test appointment free of charge or post you a home testing kit which you can post back to our laboratory
