Chronic Fatigue Syndrome Profile

About this test

Chronic Fatigue Syndrome is a confusing illness, in as much as no one really knows what causes it. It's thought, however, that viral infection or damage to the immune system may be a factor.

The illness often follows a chest and gastric infection from which the person fails to fully recover. The major feature is a severe and debilitating muscle fatigue following exertion. Females are more commonly affected and the peak incidence is between the ages of 30 - 40 years, although young children and the elderly can also develop this.

The condition improves with rest in many cases, although often not to their previous level of ability. 25% of people become chronically ill over a number of years with a marked reduction in ability.

This profile sets out to diagnose the illness by testing for Herpes virus 6, Epstein-Barr Virus Antibody, Vitamin D, C-Reactive Protein (CRP) and Lymphocyte Subsets.

Who is this test for?

Important Information

Our tests are not a substitute for seeing your doctor, especially if you are suffering symptoms. Our doctors will interpret your results based on the information you have provided, but will not diagnose, consult or provide any treatment. You will be advised to see your doctor for any necessary follow-up action.

Tests Included


Although called a vitamin, vitamin D is actually a hormone which is activated by sunshine on your skin. Vitamin D is essential for bone strength as it helps your intestines absorb calcium. However, it is thought that vitamin D also plays an important role in immune function, as well as in many chronic diseases and mental health.

Many people in the UK do not produce enough Vitamin D, especially in the winter months with fewer daylight hours. It is now recommended that you get 10 - 15 minutes of unprotected sun exposure every day to ensure you are producing enough vitamin D. In winter months, if your levels are found to be low, you may wish to take a supplement.

Inflammation Marker

C Reactive Protein (CRP) is a protein made in the liver in response to inflammation or infection in the body. It can rise very rapidly when tissues are inflamed as a result of infection. It is a non-specific test as although it can identify that infection and inflammation is occuring in the body, it cannot specify where. 

A raised level will normally be investigated further to identify the source of the inflammation.
