Albumin is the most abundant protein in blood plasma. It is produced by well-differentiated hepatocytes, and plays an important role in maintaining osmotic pressure. The normal range of albumin in plasma is 3.4-5.4 grams per deciliter (g/dL). Decreased levels of serum albumin may be a sign of kidney diseases or liver diseases (like hepatitis and cirrhosis). This kit is used to quantify the albumin level.
