Fasting test?You must be fasting for this blood test. The vitamin B12 determination can take longer than 24 hours.
Fatigue - What is it?Fatigue basic is a standard blood test that we have put together that is specifically aimed at identifying the most common reasons for fatigue In this package we look at your vitamin D, vitamin B12, thyroid hormone, glucose, iron, magnesium and finally we look at whether there is anemia by determining the hemoglobin.
The mechanism of fatigue can be found in the central nervous system in particular, but also in the transport of blood, the production of building materials for energy supply to cells and last but not least the functioning of muscles.
With blood tests for vitamins, minerals, hemoglobin, thyroid hormone and glucose you can ultimately successfully treat more than half of the people with fatigue.
Fatigue is caused by various factors, so every pathophysiology is different. The pathophysiology can be divided according to cause. With this blood test for fatigue we focus on the most common causes. Want to read more about the causes of fatigue? Read it in the blog.
What do we determine?
Blood: Hemoglobin & MCVA blood test for fatigue is not complete without testing for anemia. Anemia mainly causes fatigue and feeling weak and lethargic. However, there are many different types of anemia. We make a distinction between macrocytic anemia, normocytic anemia and microcytic anemia by looking at the MCV. The MCV is a way to start looking for the cause. A blood test for anemia therefore always contains the Hb value and the MCV value. Since the normal values differ between men and women for anemia, the doctor will take this into account in the interpretation and advice.
Vitamin: Vitamin D and Vitamin B12We determine the inactive form of vitamin D, we call this vitamin D3 or cholecalciferol or in molecular terms the 25-hydroxy vitamin D. It is important to keep the inactive form (25-hydroxy vitamin D) between 50 and 150 nmol / L. However, for people with persistent complaints it is advisable to maintain a higher minimum value.

Vitamin B12 (cobalamin) is necessary for the production of red blood cells and the proper functioning of the nervous system. Vitamin B12 is almost exclusively found in animal products, so vegans are recommended to have a blood test done if they have symptoms. With a deficiency you will experience tingling, fatigue, dizziness, memory loss and muscle weakness. Want to read more about vitamin B12? Blood test vitamin B12 page
Trace element: Iron & MagnesiumIron plays a role in the oxygen supply and removal by red blood cells through the production of hemoglobin. It also plays a role in the immune system. If you get tired quickly, get out of breath quickly and suffer from restless legs, you could well have an iron deficiency. Iron deficiency anemia is most common in women of childbearing age.
Magnesium plays an important role in alertness, muscle strength and heart rhythm. A magnesium deficiency is often secondary to a potassium or calcium deficiency. If you opt for mineral research, we will also test these. A magnesium deficiency is often caused by medications such as antibiotics, abdominal complaints such as diarrhea, kidney abnormalities and alcohol abuse.
GlucoseGlucose is the most important sugar for our body. The vast majority of carbohydrates are converted into glucose and ultimately converted into energy. If there are disturbances in glucose uptake, processing and / or breakdown, then something is not going well with the energy balance. An example of this is diabetes, in which sugar from the blood is not absorbed into the body. With diabetes, the body cannot use glucose. So there is a shortage of sugar and therefore a shortage of energy. A glucose deficiency can then cause fatigue because cells do not receive enough energy for their own tasks to keep other processes in the body going.
Thyroid hormoneDuring the thyroid hormone blood test we determine TSH and, if this is abnormal, the FT4. You can read a detailed description of the thyroid hormone on Thyroid hormone package 001 page
