In a serum measurement device, an analyte concentration measurement apparatus facilitates sampling and analysis of analytes in body fluid and includes an implantable serum sampling catheter comprising a biocompatible tubing enclosing a vacuum release lumen and a serum lumen that are interconnected by a port. The serum lumen is separated from the sampling catheter exterior by a membrane barrier. The sampling catheter is configured for drawing a serum sample from a body fluid compartment by creation of suction in the serum lumen.
