Abstract
Official abstract text for this publication.
A system for electrochemically detecting AST and ALT includes a first sampler for producing pyruvate from ALT and a second sampler for producing pyruvate from AST. The system further includes an electrochemical test strip for receiving processed samples from the first and second samplers, the processed samples containing pyruvate. The system further includes a meter for reading the electrochemical test strip and indicating an amount of AST and ALT in the sample.
First claim
Opening claim text (preview).
What is claimed as new and desired to be protected by Letters Patent of the United States is: 1 . A system for electrochemically detecting ALT, the system comprising: a sampler for producing pyruvate from ALT; an electrochemical test strip for receiving a processed sample from the sampler, the processed sample containing pyruvate; and a meter for reading the electrochemical test strip and indicating an amount of ALT in the sample. 2 . The system of claim 1 , wherein the sampler contains L-Alanine+alpha-Ketoglutarate. 3 . The system of claim 2 , wherein the electrochemical test strip includes phosphate and ferricyanide. 4 . The system of claim 3 , wherein the electrochemical test strip further includes pyruvate oxidase. 5 . The system of claim 4 , wherein the sampler includes a heating element. 6 . The system of claim 4 , wherein the electrochemical test strip includes a heating element. 7 . The system of claim 5 , wherein the sampler includes a timer. 8 . The system of claim 5 , wherein the meter includes a timer. 9 . A system for electrochemically detecting AST, the system comprising: a sampler for producing pyruvate from AST; an electrochemical test strip for receiving a processed sample from the sampler, the processed sample containing pyruvate; and a meter for reading the electrochemical test strip and indicating an amount of AST in the sample. 10 . The system of claim 9 , wherein the sampler contains L-Aspartic acid+alpha-Ketoglutarate. 11 . The system of claim 10 , wherein the sampler further contains oxaloacetate decarboxylase. 12 . The system of claim 11 , wherein the electrochemical test strip includes phosphate and ferricyanide. 13 . The system of claim 12 , wherein the electrochemical test strip further includes pyruvate oxidase. 14 . The system of claim 13 , wherein the sampler includes a heating element. 15 . The system of claim 13 , wherein the electrochemical test strip includes a heating element. 16 . The system of claim 14 , wherein the sampler includes a timer. 17 . The system of claim 14 , wherein the meter includes a timer.
