Abstract
There is described a process for improving precision in an analytical test for a target analyte in a sample. The process includes prior to analyzing the sample for a target analyte via a biosensor, introducing to an analytical zone defined by the biosensor fluid comprising an effective amount of the target analyte.
Claims15
A process for improving precision in a diagnostic test utilizing a biosensor comprising:
- contacting a sample suspected of having a target analyte therein with an amount of a fluid comprising an amount of the target analyte prior to analysis of the sample for the target analyte;
- wherein the contacting is done within an analytical zone defined by the biosensor, the biosensor configured for detection of a presence of the target analyte;
- and
- wherein the contacting is effective to increase a degree of precision in the analysis for the target analyte.

A process for improving precision in a diagnostic test comprising:
- delivering a first sample to an analytical zone of a biosensor for determination of an amount of a target analyte in the first sample;
- introducing into the analytical zone a fluid comprising an effective amount of the target analyte;
- and
- after the introducing, delivering a second sample to an analytical zone of the biosensor for determination of an amount of a target analyte in the second sample.

A system for improving for improving precision in a diagnostic test comprising:
- a biosensor defining an analytical zone and configured for the detection of a target analyte;
- a wash fluid source comprising a fluid, the wash fluid comprising an amount of the target analyte;
- a first delivery mechanism in communication with the wash fluid source for introducing the wash fluid to the analytical zone;
- a second delivery mechanism in communication with a sample suspected of comprising the target analyte for introducing the sample to the analytical zone following introduction of the wash fluid to the analytical zone;
- wherein upon delivery of the wash fluid to the analytical zone and delivery of the sample, the amount of the target analyte in the wash fluid is effective to increase a degree of precision in the analysis for the target analyte in the sample.
