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 iron the lab techniques used; look at the individual laboratory reference values to interpret a specific test (for instance, your own). Serum iron Serum iron is a medical laboratory test that measures the amount of circulating iron that is bound to transferrin (90%) and serum ferritin (10%). Clinicians order this laboratory test when they are concerned about iron deficiency, which can cause anemia and other problems. 65% of the iron in the body is bound up in hemoglobin molecules in red blood cells. About 4% is bound up in myoglobin molecules. Around 30% of the iron in the body is stored
