<p><P>PROBLEM TO BE SOLVED: To provide a system and method for determining whether the data for a growth curve represents or exhibits valid or significant growth. <P>SOLUTION: A data set representing a sigmoid or a growth-type curve, such as a PCR curve, is processed to determine whether the data exhibits significant or valid growth. A first or a second degree polynomial curve that fits the data is determined, and a statistical significance value for the curve fit is determined. If the significance value exceeds a significance threshold, the data is considered to not represent significant or valid growth. If the data does not represent the significant or valid growth, the data set may be discarded. If the significance value does not exceed the significance threshold, the data is considered to represent significant or valid growth. If the data set is determined to represent the valid growth, the data is further processed to determine a transition value in the sigmoid or the growth curve, such as the end of the baseline region or the elbow value or Ct value of the PCR amplification curve. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
