Iron in Urine
This test measures the same as Iron from blood, but is more expensive, it is however interesting if you don't want to go to an injection station or want to combine this with another urine test.
Everyone knows what iron is but what does it do in your blood? It is a part of and hemoglobin, an important tool for red blood cells to bind oxygen. We get it through our food. It is absorbed into the body and distributed by transferrin, a protein from the liver.
About 70% of the iron in our bodies is linked to hemoglobin in red blood cells, the rest is linked to ferritin and stored in tissues. If there is not enough iron absorbed through food, the stores in the body will shrink. This can lead to anemia because not enough red blood cells can be formed.
A surplus (hemochromatosis) is also not good and can lead to problems with the liver, heart or pancreas.
For example, in complaints of fatigue. In cases of anemia, this determination can help identify the cause of the anemia.
The iron level in the blood varies greatly throughout the day, which is why the binding capacity (transferrin) is often measured in addition to iron. This often says more about iron metabolism than the level alone.
