Abstract
A method and apparatus for determining an abnormal component of blood functions is described. A whole blood sample is cycled as a laminar flow through a flow cell having a measuring element prepared by plating the surface of a plate-shaped quartz oscillator with a protein layer. The amount of adhesion of the blood component on the protein layer is determined on the basis of the change in resonance frequency of the measuring element. The measured value is compared with a standard value of adhesion for blood from a healthy individual.
