Albumin is a protein manufactured by the liver. It helps balance the amount of blood flowing through the arteries and veins and moves the calcium, progesterone, bilirubin and medications through a person’s blood.
Serum albumin test is used to screen for and help diagnose a liver disorder or kidney disease, and sometimes it is used to evaluate nutritional status, especially in hospitalized patients.
The normal range of albumin levels is 3.4- 5.4 grams per deciliter (g/dL).
Decreased levels of albumin may indicate:
- A low protein diet
- Excessive burns
- Nephrotic syndrome
- Carcinoid syndrome
- Crohn’s disease, sprue, or Whipple’s disease – all malabsorption syndromes
- Liver diseases such as hepatocellular necrosis, cirrhosis or hepatitis
Increased levels of albumin may indicate:
- Too much intake of certain drugs including insulin, growth hormones, androgens and anabolic steroids
