There are also other tests, including free T3 and free T4 and thyroid antibodies, which are essential. I also look for associated problems such as gluten intolerance, food allergies, and heavy metals, as well as deficiencies of vitamin D, selenium, vitamin A, zinc, and omega-3 fats.
While the spleen functions chiefly to filter blood, it also stores red blood cells and platelets. In instances where extreme bleeding occurs, red blood cells, platelets, and macrophages are released from the spleen. Macrophages help to reduce inflammation and destroy pathogens or damaged cells in the injured area.
The spleen is part of your lymphatic system, which fights infection and keeps your body fluids in balance. It contains white blood cells that fight germs. Your spleen also helps control the amount of blood in your body, and destroys old and damaged cells. Certain diseases might cause your spleen to swell. You can also damage or rupture your spleen in an injury, especially if it is already swollen. If your spleen is too damaged, you might need surgery to remove it. You can live without a spleen. Other organs, such as your liver, will take over some of the spleen's work.
