title: Continuous monitoring of urea in blood during dialysis.
abstract: Urease was immobilized to porous glass and used in combination with a conductivity meter for determining urea in standard solutions as well as in blood from a patient undergoing dialysis. The sampling unit involves a possibility for heparinization at the sampling point and a dialysis step prior to exposure to the enzyme column. The unit operates in a linear mode in the concentration range 5-50 mM. Monitoring of dialysis process gave good correlation with off-line analyses.
