Abstract

Medical systems for detecting a genetic variation in a polynucleotide analyte in a sample. A fluorophore is attached to a first primer, a quencher is attached to a second primer, and the first primer and the second primer are specific for the polynucleotide analyte. The primers are configured to amplify the polynucleotide analyte having the genetic variation and a corresponding polynucleotide analyte lacking the generic variation. There is a detectable difference between a change in signal generated by the fluorophore and quencher, and measured by a sensor of the medical system, when using the first and second primers to amplify the polynucleotide analyte with the genetic variation, and a change in signal generated by the fluorophore and quencher, and measured by the sensor of the medical system, when using the first and second primers to amplify the corresponding polynucleotide analyte lacking the genetic variation.
