Albumin is a serum protein, produced by the liver. Among its functions are:
  • Maintaining water balance in the blood through osmotic pressure
  • Transportation of blood components

50–60% of total serum protein is albumin, and the rest is made, primarily, of globulins.

Increased albumin levels may be seen in:

  • Dehydration

Decreased albumin levels may be seen in:

  • Liver disease (decreased production)
  • Malnutrition (decreased production)
  • Diarrhea (increased loss)
  • Renal disease (increased loss)
  • Severe burns (increased loss)
  • Pregnancy (dilutional)
