This test includes (expand individual tests for details):


Inflammation Marker

C Reactive Protein (High Sensitivity)

C-Reactive Protein (CRP) is an inflammation marker used to assess whether there is inflammation in the body. Inflammation is your body protecting your tissues if you have been injured or have an infection. It is also used as a screen for auto-immune diseases.


Iron Status

Iron (TIBC included)

This test measures how much iron is in your blood. It will identify iron deficiency or iron overload. Symptoms for both include: fatigue, muscle weakness, moodiness and difficulty concentrating.

Total iron binding capacity (TIBC)

Total iron binding capacity (TIBC) is a measure of the amount of iron that can be carried through the blood. 


This test will measure your Transferrin levels. Transferrin binds to iron and transports it throughout your body. Low levels indicate iron deficient. High levels indicate iron overload


This test will measure your Ferritin levels. Ferritin stores iron in the body. Ferritin is tested to identify the storage capacity of iron in the body.


Thyroid Function

Free T4

Thyroxine (T4) is one of two major hormones produced by the thyroid gland (the other is called triiodothyronine (T3)). This test can tell whether the thyroid is performing properly. Thyroid hormones help regulate your metabolism (how the body functions).




Thyroid Stimulating Hormone (TSH) is produced in the pituitary gland. It tells the thyroid gland to produce thyroid hormones (T3 & T4.) High levels of TSH indicate an underactive thyroid while low levels indicate an overactive thyroid.



Vitamin D (25 OH)

Vitamin D is a hormone which is created by sunlight on your skin. Abnormal levels of vitamin D can indicate bone disorders, nutrition problems, organ damage, or other medical conditions. Many people in the UK have low Vitamin D levels.
