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
Blood sugar level given in terms of whole blood, but most laboratories now measure and report plasma or serum glucose levels. Because red blood cells (erythrocytes) have a higher concentration of protein (e.g., hemoglobin) than serum, serum has a higher water content and consequently more dissolved glucose than does whole blood. To convert from whole-blood glucose, multiplication by 1.14 has been shown to generally give the serum/plasma level To prevent contamination of the sample with intravenous fluids, particular care should be given to drawing blood samples from the arm opposite the one in which an intravenous line is inserted. Alternatively, blood can be
