Correct and incorrect threshold settings

Threshold set correctly

The threshold is set in the exponential phase of the

amplification curve. Threshold settings above or below

the optimum increase the standard deviation of the

replicate groups.

Threshold set too low

The threshold is set below the exponential phase of the

amplification curve. The standard deviation is

significantly higher than that for a plot where the

threshold is set correctly. Set the threshold up into the

exponential phase of the curve.

Threshold set too high

The threshold is set above the exponential phase of the

amplification curve. The standard deviation is

significantly higher than that for a plot where the

threshold is set correctly. Set the threshold down into

the exponential phase of the curve.
