Abstract

A computer-implemented method for determining the amount of an analyte in a sample comprises associating a nucleic acid amplification assay defined at least partly by user-defined assay parameters to the sample. The assay is performed by dissolving a unit-dose reagent with a solvent, wherein the solvent includes one or more amplification oligomers adapted to amplify a region of the analyte and the reagent does not include an amplification oligomer for performing the assay. A reaction mixture, including the dissolved reagent and the sample, is exposed to a temperature condition and measurements of fluorescence indicative of an amount of amplification products formed during the exposing are collected. The measurements are assessed with a computer using data analysis parameters provided by the user to compute results indicative of the amount of the analyte in the sample.

First claim

1 . A computer-implemented method for determining the amount of an analyte in a sample, the method comprising:
(a) associating a nucleic acid amplification assay to the sample, wherein the nucleic acid amplification assay is defined at least partly by a set of user-defined assay parameters; (b) performing the nucleic acid amplification assay on the sample, wherein performing the nucleic acid amplification assay includes:
(i) dissolving a unit-dose reagent with a solvent, wherein the solvent includes one or more amplification oligomers adapted to amplify a region of the analyte or a nucleic acid bound to the analyte during the nucleic acid amplification assay, and wherein the unit-dose reagent does not include an amplification oligomer for performing the nucleic acid amplification assay;
(ii) forming a reaction mixture from the dissolved unit-dose reagent and the sample; and
(iii) exposing the reaction mixture to a temperature condition to form amplification products;
(c) collecting data using a signal measuring device concurrently with the formation of amplification products, the collected data comprising periodic measurements of fluorescence indicative of an amount of amplification products formed during the exposing; and (d) using a computer programmed with an algorithm, which, when executed by the computer, is configured to cause the computer to access the collected data of step (c), and to:
(i) receive, from a user, one or more user-defined data analysis parameters, wherein the one or more user-defined data analysis parameters are variables used in processing of the collected data;
(ii) processing the collected data, using one or more of the user-defined data analysis parameters, to create processed data;
(iii) computing, using one or more of the user-defined data analysis parameters, results indicative of the amount of the analyte in the sample from the processed data; and
(iv) determining if the results determined in step (d) (iii) is a valid result using one or more of the user-defined data analysis parameters.
