Abstract
A single technique for determining Ct is provided that can be used for standard sigmoidal growth curves and for problematic growth curves, such as parabolic curves. The Ct value can be determined as the intersection of a line tangent to the growth curve at the maximum of the second derivative with a baseline of the growth curve. Such a Ct value is usable for sigmoidal curves and parabolic curves, and can provide linear calibration curves to achieve accuracy in determining initial concentrations of a sample.
