Kylt Influenzavirus A Standard is used for quantification of Influenza Virus A-positive samples by Real-Time PCR. The standard is intended to be used in combination with one of the Kylt Influenza A PCR Kits, for further information please refer to the respective Direction For Use. For a quantitative application the sample of interest is analyzed in a PCR run including the set of different Quantitative Standards; this set consist of a dilution series with defined Genome Equivalents (GE)/μl. The generated standard curve is then used to determine the concentration of Influenza A in the sample (GE/ml or g). By this, together with defined cut-off values, the clinical relevance of detected pathogens can be evaluated.
