Abstract:
1. A method of detecting and removing a foreign agent from blood or plasma, the method comprising the steps of: conjugating said foreign agent with a conjugate, said conjugate having a field gradient that quenches an NMR signal of a liquid to be tested for the presence of the foreign agent; placing said liquid in a sample testing section of a nuclear magnetic resonance device, said sample testing section sized to receive a single foreign agent and to contain a volume of liquid such that said field gradient of said conjugate quenches the entire NMR signal of the liquid in said sample testing section; applying a magnetic field to said liquid when said liquid is located in said sample testing section; testing said liquid for the presence of the foreign agent based upon said NMR signal of the liquid being entirely quenched by said conjugate; and upon determining the presence of said foreign agent, removing said foreign agent from the blood or plasma by shunting the blood or plasma through a container having a binding agent therein, said binding agent having an affinity for the foreign agent that binds the foreign agent inside the container.
