REDUCTION OF FALSE POSITIVE ON REAGENT TEST DEVICES

摘要

Methods and systems are disclosed including a reagent analyzer, comprising a test analyzing mechanism, such as an optical imaging system, configured to read a first sample of a specimen combined with a reagent configured to react with the sample in a presence of an analyte of interest and a second sample of the specimen that is not combined with a reagent, and to output one or more first signals indicative of the test analyzing mechanism reading the first and second samples; and a processor receiving the one or more first signals and executing logic to analyze the second sample responsive to the processor determining that the analyte of interest is present in the first sample. The processor may execute logic to analyze the second specimen utilizing one or more ratio algorithm and comparing the results of the algorithm against predetermined values indicative of expected color.

1. A reagent analyzer, comprising:
a test analyzing mechanism configured to read at least one property of a first sample of a specimen combined with a reagent and a second sample of the specimen, and to output one or more signals indicative of the test analyzing mechanism reading the first sample combined with the reagent and the test analyzing mechanism reading the second sample; and a processor receiving the one or more signals indicative of the reading of the first sample combined with the reagent and the reading of the second sample; the processor executing:
first logic to analyze the one or more signals to determine whether an analyte of interest is present in the first sample by quantifying a first predetermined property of the first sample combined with the reagent;second logic to analyze the one or more signals to quantify a second predetermined property of the second sample; andthird logic to verify a presence of the analyte of interest in the first sample based on the quantification of the first predetermined property and the second predetermined property.
