The Importance of Standards in Molecular-Based Assays

May 08, 2014, at 12:00 PM ET


Stimulated by the presence of emerging and re-emerging microbial threats, the need for molecular-based tests has significantly increased in the last few years. In turn, this has necessitated the use of standardized nucleic acids in clinical laboratories. In this webinar, we will discuss the importance of molecular standards in the establishment of sensitivity, linearity, and specificity during assay validation or implementation, quality assurance, quality control, and proficiency testing, and how the use of standards can contribute to improvements in assay reproducibility and reliability.
