Claim Text:
1. An apparatus for determining the coagulation time of a sample fluid containing blood components, comprising: a resonator, said resonator includes a surface, said surface of said resonator is a vibrating quartz crystal surface, said vibrating quartz crystal surface of said resonator includes non-adhesive areas ( 22 ) and adhesive areas ( 24 ) arranged in a mosaic on said vibrating quartz crystal surface, preincubation fluid containing blood components, said preincubation fluid ( 14 ) forming anchoring sites on said adhesive areas on said vibrating quartz crystal surface of said resonator, said adhesive areas of said vibrating quartz crystal surface of said resonator are adhesive with respect to said blood components of said sample fluid and said non-adhesive areas ( 22 ) of said vibrating quartz crystal surface of said resonator are non-adhesive with respect to aid blood components of said sample fluid, said vibrating quartz crystal surface of said resonator has a resonant frequency dependent on said sample fluid which engages and anchors to said anchoring sites on said adhesive areas of said vibrating quartz crystal surface of said resonator, and, said coagulation time occurs when said resonant frequency of said vibrating quartz crystal surface is at a maximum.
