ABSTRACT:
A method and apparatus is provided which measures the content of a low-molecular compound, such as glucose, cholesterol, or urea, in a complex medium, such as blood. A dialyzer is placed in contact with the complex medium so that the complex medium may pass therethrough. In addition, dialysis fluid is supplied through the dialyzer to produce a dialysate having a property which can be measured. In the preferred embodiment, an enzyme is added to the dialysate to chemically react with the low-molecular compound to produce a chemical change which can be measured.
