Abstract

Devices, systems, and methods for automatic genotyping obtain high-resolution melt data from a test sample defining a melting curve for a target nucleic acid in the test sample; obtain high-resolution melt data from a control sample defining a melting curve for a wild type of the target nucleic acid in the control sample; calculate melting curve derivatives of the melting curves for the test sample and the control sample, respectively, wherein each melting curve derivative represents a negative derivative of a fluorescence emitted from a nucleic acid sample as a function of temperature affecting nucleic acid denaturation; calculate parameters defining differences between features of the test sample and the control sample melting curve derivatives; and assign a genotype to the test sample based on a comparison of the calculated parameters to predetermined thresholds and boundaries defining genotypes.
