Hyponatremia available in many areas of the world. Raising the serum sodium concentration too rapidly may cause central pontine myelinolysis. Avoid correction that leads to a serum sodium rise of more than 12 mEq/L/day. Hyponatremia is the most commonly seen water–electrolyte imbalance. The disorder is more frequent in females, the elderly, and in people who are hospitalized. The incidence of hyponatremia depends largely on the patient population. A hospital incidence of 15–20% is common, while only 3–5% of people who are hospitalized have a serum sodium level (salt blood level) of less than 130 mmol/L. Hyponatremia has been reported in up
Serum-separating tube particles to cause blood to clot quickly. The blood sample may then be centrifuged, allowing the clear serum to be removed for testing. These tubes should be used with care when measuring drug or hormone levels because the drug or hormone may diffuse from the serum into the gel, causing a reduction in measured level. The gel in SST II tubes (which appears slightly less opaque) is supposed to have less effect on drug levels in serum. 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
