Abstract
Methods, apparatus, and systems, including computer program products, implement techniques for determining an amount of target nucleic acid ('target') in a sample. Signal data is received for a plurality of cycles of an amplification experiment performed on the target and a standard nucleic acid ('standard'). The signal data includes a series of signal values indicating a quantity of standard present during cycles of the standard amplification, and a series of signal values indicating a quantity of target present during cycles of the target amplification. A target growth curve value is defined using the target signal values and a standard growth curve value is defined using the standard signal values. An initial amount of the target is calculated according to a calibration equation using an initial amount of the standard, and the target and standard growth curve values, where the calibration equation is a nonlinear equation.
