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 free light-chain measurement Serum free light-chain measurement Immunoglobulin light chains that are circulating in serum in a free (unbound) state are called free light chains (FLCs). Measurement of the serum level of FLCs became practical as a clinical blood test in recent decades. These tests are used as an aid in the diagnosis and monitoring of multiple myeloma and related disorders. There are two types of immunoglobulin light chain produced in humans, designated by the Greek letters kappa (κ) and lambda (λ). Comparing the ratio of κ FLCs to λ FLCs in a person's serum against reference ranges indicates whether that person may
