    Quantitative qPCR is method for the accurate quantification of nucleic acids. Yet it may generate erroneous results if the amplification process is obscured by inhibition or generation of aberrant side-product. Herein we present a statistical approach based on multivariate analysis of the amplification response data generated in qPCR. The amplification trajectory in its most dynamic phase is fitted with a suitable model. Two parameters of this model, related to amplification efficiency, are then used for calculation of the Z-score statistics. Each studied sample is compared to a predefined reference set of reactions. A probabilistic decision for each individual Z-score is then used to identify the majority of inhibited reactions in our experiments. We demonstrate improved identification performance using the multivariate approach Finally we stress that the performance of the amplification kompatibility test as a quality control procedure depends on the quality of the reference set
