Albumin

The various functions of Albumin in the blood stream include the transport of insoluble organic anions, the binding of toxic heavy metals, the transport of poorly soluble hormones, the maintenance of plasma colloidal osmotic pressure, and the provision of a reserve store of protein. Low serum values can result from malnutrition or liver disease, an increase in catabolism, increased excretion in urine or feces, or a change in distribution between the intravascular and extravascular compartments. High serum values can result from dehydration.
