  • Patent number: 6743596
    Abstract: A method is disclosed for determining if a patient is hypercoagulable, hypocoagulable or normal. The test involves providing a test sample from the patient and initiating coagulation in the sample in the presence of an activator, which is added to the sample in an amount which will result in intrinsic tenase-dependent fibrin. Then the formation of the intrinsic tenase-dependent fibrin polymerization is monitored over time so as to derive a time-dependent profile, with the results of the fibrin polymerization monitoring determining whether the patient is hypercoagulable, normal or hypocoagulable. The coagulation activator is added in an amount that triggers a thrombin explosion that is dependent on the propagation phase and amplification pathways. In this way, a single assay can assess the hemostatic potential of a sample.

  • Patent number: 6596532
    Abstract: A device and method are provided for isolating and culturing microorganisms from a bulk fluid sample. The device comprises a container having therein a polymeric immobilization layer having interstitial spaces between polymer chains such as a gel matrix. The interstitial spaces are of an average size less than an average size of microorganisms to be separated from the sample and cultured. A bulk fluid sample is applied to the immobilization layer where fluid is absorbed by the layer and microorganisms remain on the surface of the layer. After culturing, microorganism colonies are readily accessible on the surface of the layer for harvest and testing. The immobilization layer may contain one or more of nutrients for microorganism growth, lytic agents, lytic enzymes, antibiotics, antibiotic neutralizers, indicators, detergents and selective agents. An adjacent support layer may be above and/or below the immobilization layer.
