Iron

Iron is a mineral found within the blood, and is needed to help create haemoglobin which is a protein in the blood responsible for the transport of oxygen within the body's blood cells. If the body does not have enough haemoglobin, the muscles do not get enough oxygen and cannot work properly. It is important for people to have the correct amount of iron otherwise they will feel more tired and become Anaemic. The body's iron stores are sourced from one's diet and from the breakdown and turnover of red blood cells. When a test reveals low iron levels, a change in diet or added supplements can be used for treatment.

Total Iron Bounding Capacity (TIBC)

Too much and too little iron in the body can lead to problems. The Total Iron Bounding Capacity Test measures the amount of iron within the bloodstream. The test also measures how well the iron is transported around the body via the transferrin. Anemia is the condition of not having enough iron in the blood. Having too much iron in the blood is rarely caused by an overdose of vitamins or supplements and can cause symptoms ranging from feeling tired and weak to an irregular heart rhythm.

Vitamin D

Vitamin D is a vitamin that's essential for many functions in your body, including bone and muscle health. Vitamin D can be found in food, supplements, and fortified foods. If you don't get enough vitamin D, you may develop osteoporosis or muscle weakness. An average vitamin D level is 20 to 50 ng/mL. If you have a low vitamin D level, we may recommend that you take a vitamin D supplement or eat foods fortified with vitamin D.

Thyroxine (T4)

Thyroxine or T4 exists 

Thyroxine (T4) is the hormone that has several important functions in the body, including speeding up the rate of metabolism, growth and energy levels. We test the thyroxine within the body to get an indicator of how well the thyroid is functioning. There are different treatments depending on if the thyroid is under or over the normal levels.

Ferritin

Ferritin is the protein that stores iron in the body. Iron is needed to provide muscles with oxygen so that they receive the energy they need to function properly. Ferritin will release the iron when needed and is kept within the body's cells, most commonly found in the liver. We check ferritin levels to ensure that there is proper storage of iron in the body's cells otherwise the iron will be depleted quickly.

Transferrin Saturation

Transferrin Saturation is tested to measure how much the protein is saturated by iron that it will then transport around the body. The transferrin binds itself to iron and ensures it delivers the haemoglobin and oxygen the iron has provided to the muscles to be used as energy for movement.

 

Free thyroxine

The thyroid gland produces a two hormones. One of these thyroxine or T4 exists as free T4 meaning that it hasn't bonded to the blood protein. Most of the T4 is bonded to protein however, the type that isn't is available to the body and tissues. This test measures only the free T4 in the blood as that is the hormone most available to the rest of the body to use. 


hs-CRP

To check inflammation levels, we conducted an advanced CRP evaluation. C-Reactive Protein (CRP) is a protein found in the blood which increases in response to inflammation. CRP is produced by the liver in response to inflammation. It is a biomarker of inflammation that is strongly associated with the risk of cardiovascular diseases, such as heart attack and stroke. High levels of CRP are found in people with chronic inflammatory diseases, such as rheumatoid arthritis, and in people who have had a recent heart attack or stroke. CRP is not a specific marker for any one disease, but it is a valuable indicator of inflammation.

Additional Insight from Dr Sameer Nakedar, MBBS, MRCGP, PGCert

"This panel of tests looks for some common causes of tiredness which can be corrected easily with medication if appropriate.

- Iron studies are checked. If iron stores are low, this can lead to anaemia, amongst other symptoms. If too high, this can also be an issue.

- Low Vitamin D levels can cause tiredness; hence, this is tested.

- Thyroid disorders, particularly an underactive thyroid, can also present with tiredness and are included in this screen.

All of these markers can give a start to some causes of fatigue, which you can tackle early and optimise appropriately with the correct medical help."

Why Take a Tiredness and Fatigue Blood Test

If you have found yourself more tired than usual and cannot easily explain the change due to an increase in activity or lifestyle change, it is important to be tested as the symptoms may be the cause of a change within the body. There are many factors that could account for an increase in tiredness and fatigue, the lack of vitamin D from reduced sun exposure is a large cause within the population for feeling tired. There are several other more serious reasons for feeling tired, including an over or under-acting thyroid, iron deficiency, lack of ferritin production and other impaired protein productions. Taking a Tiredness and Fatigue Blood Test will aid our trained doctors in treatment or lifestyle changes to get you feeling energised and less fatigued.
