Reference range is based on ambulatory patients in sitting position. Patients in recumbent position may have lower values by approximately 6%.    
Use:Albumin is the major serum protein, accounting for roughly half the total protein in most individuals. Excessive loss from the kidneys, GI tract, or skin such as with burns as well as decreased protein synthesis from malnutrition or liver disease can cause low serum albumin and to a lesser extent low total protein. Elevated albumin and total protein can be seen with dehydration. Elevated total protein with normal albumin suggests other serum proteins are elevated, seen most frequently in those with multiple myeloma. Albumin is also used for evaluation of suspected hepatic disease.
