What is the normal value of albumin? Albumin is synthesized by the parenchymal cells of the liver and is the main protein component of the blood serum, while its normal value ranges from 35 g/L to 51 g/L. When it exceeds this value, we call it elevated albumin. It is mainly due to blood concentration due to blood loss, or due to multiple myeloma, systemic lupus erythematosus, multiple sclerosis, etc., which cause increased albumin, and decreased protein due to malignancy, or severe tuberculosis, malnutrition. There is also hypoproteinemia caused by low protein, general protein we have to give supplemental human albumin, albumin injection, or nutritional support, or eat protein powder and other supplements.
