低白蛋白血症
Hypoalbuminemia (or hypoalbuminaemia) is a medical sign in which the level of albumin in the blood is low. This can be due to decreased production in the liver, increased loss in the gastrointestinal tract or kidneys, increased use in the body, or abnormal distribution between body compartments. Patients often present with hypoalbuminemia as a result of another disease process such as malnutrition as a result of severe anorexia nervosa, sepsis, cirrhosis in the liver, nephrotic syndrome in the kidneys, or protein-losing enteropathy in the gastrointestinal tract. One of the roles of albumin is

低白蛋白血症(Hypoalbuminemia、或低人血清白蛋白血症(hypoalbuminaemia))是一種醫學病症，其中在血清的白蛋白(Human serum albumin)的水平異常的低。它是低蛋白血症(Hypoproteinemia)的一種具體形式。. 白蛋白是在人體內的主要蛋白，佔大約總人體血浆蛋白質質量的55-60％。許多激素、药物，和其它分子在血液中大多是結合到白蛋白裡，並在轉為"生物活性"(biologically active)之前必須被釋放。例如，鈣離子結合於白蛋白、且"低白蛋白血症"導致增加游離的鈣離子。 白蛋白在肝臟中合成，低血清白蛋白可以標示出肝衰竭(Liver failure)或諸如肝硬化或慢性肝炎等疾病。低白蛋白血症也可以存在如腎病症候群(NS)的一部分，其中蛋白質由於腎損害丟失在尿液中。低白蛋白水平為"營養不良"或(Protein losing enteropathy)的指標。 低白蛋白血症經由"膠體滲透壓的降低"可能導致全身性水肿(腫脹)。 人血清白蛋白(human serum albumin)水平是肝功能測試標準面板的一部分。低於"每分升3.5克"(3.5 grams per deciliter)水平通常被認為是低的。
