Hyponatremia to 30% of elderly patients in nursing homes and is also present in approximately 30% of depressed patients on selective serotonin reuptake inhibitors. People who have hyponatremia who require hospitalisation have a longer length of stay (with associated increased costs) and also have a higher likelihood of requiring readmission. This is particularly the case in men and in the elderly. Hyponatremia Hyponatremia is a low sodium level in the blood. It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. Symptoms can be absent, mild or severe. Mild
Human serum albumin domain. Serum albumin is commonly measured by recording the change in absorbance upon binding to a dye such as bromocresol green or bromocresol purple. Serum albumin concentration is typically 35–50 g/L (3.5–5.0 g/dL). Hypoalbuminemia means low blood albumin levels. This can be caused by: Hyperalbuminemia is an increased concentration of albumin in the blood. Typically, this condition is due to dehydration. Hyperalbuminemia has also been associated with high protein diets. Human albumin solution or HSA is available for medical use, usually at concentrations of 5–25%. Human albumin is often used to replace lost fluid and help restore blood volume in
