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.
In this article. The spleen is a delicate, fist-sized organ under your left rib cage near your stomach. It contains special white blood cells that destroy bacteria and help your body fight infections. The spleen also makes red blood cells and helps remove, or filter, old ones from the body's circulation. A layer of tissue entirely covers the spleen in a capsule-like fashion, except where veins and arteries enter the organ. This tissue, called the splenic capsule, helps protect the spleen from direct injury.
