[73824485]
An internal biom? Rieux investigation was conducted. Results are as follows: a difference of quantification up to 1 log and sometimes more than 1 log was observed. As the downstream applications are qualitative and/or quantitative, the decrease of performances in downstream application could lead to:? A risk of false negative for qualitative tests,? Invalid results when extracted and amplified internal control is not within specifications,? Under-quantification for viral load results for quantitative tests we have confirmed the issue for the following customer's application specificity:? Impact when using a high sample input volume, from 200? L and up to 1 ml? Impact when double stranded nucleic acid applications with small (<40kbp) and medium genome sizes (
