Abstract:
1. A method comprising the steps of: selecting a first test cartridge having a first channel with an anticoagulant/antithrombotic as a reagent therein and a second channel without the anticoagulant/antithrombotic as a reagent therein; preparing a first plasma sample that has a clotting time that may be altered by the presence of the anticoagulant/antithrombotic reagent; adding a first portion of the first plasma sample to the first channel of the first cartridge; adding a second portion of the first plasma sample to the second channel of the first cartridge; determining the time required for a clot to be formed in each of the first and second channels for the first plasma sample; preparing a second plasma sample that includes an agent capable of neutralizing the anticoagulant/antithrombotic reagent; selecting a second test cartridge having a first channel with the anticoagulant/antithrombotic as a reagent therein and a second channel without an anticoagulant/antithrombotic as a reagent therein; adding a first portion of the second plasma sample to the first channel; adding a second portion of the second plasma sample to the second channel; and determining the time required for a clot to be formed in each of the first and second channels for the second plasma sample, wherein the anticoagulant/antithrombotic reagent is heparin.
