Exercise-associated hyponatremia sodium blood serum or plasma test. Hyponatremic encephalopathy may be detect using brain imaging studies and pulmonary edema may be confirmed by x-ray. Traditional prevention of EAH focuses on reducing fluid consumption to avoid fluid retention before, during, and after exercise. However, since this can risk dehydration, an alternative approach is possible of consuming a substantial amount of salt prior to exercise. It is still important not to overconsume water to the extent of requiring urination, because urination would cause the extra salt to be excreted. In a published statement of the Third International Exercise-Associated Hyponatremia Consensus Development Conference, researchers
Serum iron in other molecules in cells throughout the body. None of this iron is directly accessible by testing the serum. However, some iron is circulating in the serum. Transferrin is a molecule produced by the liver that binds one or two iron(III) ions, i.e. ferric iron, Fe; transferrin is essential if stored iron is to be moved and used. Most of the time, about 30% of the available sites on the transferrin molecule are filled. The test for serum iron uses blood drawn from veins to measure the iron molecules that are bound to transferrin, and circulating in the blood. The
