1. A system for detecting the impact of and correcting for interfering effects of auto-fluorescence, fluorescence quenching, and fluorescence-signal deterioration on fluorescence emission data resulting from fluorescence measurements, said system comprising:
- (i) a device for supporting one or a plurality of samples selected from the group consisting of drug-candidate samples and patient-specimen samples in an inspection station,(ii) one or a plurality of fluorescence signal detectors which are positioned relative to the inspection station so that a fluorescence signal emitted from the samples impinges on the fluorescence signal detectors, and(iii) a fluorescence signal processing unit programmed to perform the steps ofreceiving fluorescence emission data generated by the fluorescence signal detectors,determining values of a plurality of fluorescence identification parameters from said fluorescence emission data including at least first and second corresponding fluorescence identification parameters,storing the determined values in such a manner that all the determined values which relate to any one of the samples are linked,creating a multi-dimensional histogram or distribution of the determined values of the fluorescence identification parameters,determining thresholds for the determined values of the fluorescence identification parameters from said multi-dimensional histogram or distribution, which thresholds are indicative of interfering effects selected from the group consisting of auto-fluorescence, fluorescence quenching, and fluorescence-signal deterioration, wherein the threshold for the determined values of the first fluorescence identification parameter is a function of the corresponding second fluorescence identification parameter,analyzing the determined values of the plurality of fluorescence identification parameters whether or not the determined values fulfill one or a plurality of criteria with respect to the thresholds,supplying as output information fluorescence emission data influenced by the interfering effects, fluorescence emission data not affected by the interfering effects, or fluorescence emission data influenced by the interfering effects and fluorescence emission data not affected by the interfering effects, andusing the output information to detect at least one of false positive drug-candidate test results in the fluorescence emission data, false negative drug-candidate test results in the fluorescence emission data, false positive diagnostic test results in the fluorescence emission data, and false negative diagnostic test results in the fluorescence emission data.

Abstract
A method for identifying the impact on data, such as experimental data, of interfering effects, such as unwanted auto-fluorescence, fluorescence quenching, and fluorescent-sample deterioration, whether or not the data fulfill certain criteria with respect to a threshold indicative of the interfering effects.
