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-separating tube Serum-separating tube Serum-separating tubes, also known as serum separator tubes or SSTs, are used in medical clinical chemistry tests requiring blood serum. SSTs are sometimes called "marble-top tubes," "tiger-tops," or "gold-topped tubes", referring to the stoppers which are either gold, red with a gold ring on top, or marbled red and grey. Marble-top tubes are also referred to as "tiger-tops" in some clinics. SPS tubes have a paler colour, sometimes leading confusion; these are known as "yellow tops" not "gold". Trademarked versions include Covidien "Corvac" tubes. They contain a special gel that separates blood cells from serum, as well as
