Answer

The serum oncotic pressure partially regulates albumin synthesis. The regulation site may be the oncotic content in the hepatic interstitial volume because albumin synthesis is inversely related to the content of this volume. Conditions that increase other osmotically active substances in the serum tend to decrease the serum albumin concentration by decreasing synthesis. Examples include elevated serum globulin levels in hepatitis and hypergammaglobulinemia.
