The significance represented by lowered albumin may be seen in malnutrition, liver disease, severe burns, acute major blood loss, kidney disease, and many other conditions. Albumin is an important nutrient in the body and is the predominant protein in human plasma, synthesized by the liver. Albumin is an indicator of liver function tests. Albumin has an important physiological function in the body, can maintain the body nutrition and plasma colloid osmotic pressure and so on. Reduced clinical significance of albumin may be seen in malnutrition, dysfunction of hepatic synthesis of albumin, such as acute hepatitis, cirrhosis; also seen in severe burns, acute hemorrhage, pleural and abdominal fluid, nephropathy, malignant neoplasm, severe tuberculosis, congenital albumin deficiency and other diseases. If low albumin is detected during the examination, it is recommended to go to the hospital for a comprehensive evaluation by the physician in conjunction with other examination results.
