The invention relates to a method for the quality assessment of nucleic acid amplification reactions which is based on a mathematical approach for the quality assessment of complete nucleic acid amplification reactions and comprises the following steps: a) Carrying out an amplification reaction for at least one nucleic acid target molecule, b)Collecting time-related data reflecting the course of the amplification reaction, c) Fitting these time-related data with a growth model equation comprising at least one parameter, d) Obtaining, from said fitting process, at least one value for the at least one parameter.
