Novel internal controls for real-time PCR assays.
In the 19 years since the first descriptions of the PCR (1 ), nucleic acid amplification methods have made the transition from research to clinical laboratories. Molecular diagnostics are now firmly established as part of laboratory medicine, with applications in genetics, oncology, pharmacology, and infectious disease. Routine diagnostic applications of these methods have been made possible by...
متن کاملMaking internal amplification control mandatory for diagnostic PCR.
The explosive increase since the beginning of 1990s in the number of publications reporting PCR-based methods for detection or molecular typing of food-borne pathogens has attracted the attention of end user laboratories. However, the well-recognized difficulties in reproducing published tests due to variation in the performance of PCR thermal cyclers (7) and in efficiencies of different DNA po...
متن کاملConsiderations for optimization of microRNA PCR assays for molecular diagnosis.
The remarkable stability of microRNAs in biofluids underlies their potential as biomarkers, but their small size presents challenges for detection by RT-qPCR. The heterogeneity of microRNAs, with each one comprising a series of variants or 'isomiRs', adds additional complexity. Presented here are the key considerations for use of RT-qPCR to measure microRNAs and their isomiRs, with a focus on p...
متن کاملPractical Optimization Considerations For Diagnostic Knowledge Representation
Using practical criteria for the selection of a diagnostic knowledge representation, businesses can optimize the choice to their specific business goals, processes, and organization structure. This optimization involves compromises, as there are tradeoffs among ease of acquiring the diagnostic knowledge, ease of maintenance, and ease of use in troubleshooting. We present a set of considerations...
متن کاملSimple technique for internal control of real-time amplification assays.
BACKGROUND In real-time PCR assays, the most accurate way to identify false-negative results, e.g., those caused by PCR inhibitors, is to add to samples an internal control that will be coamplified with the target (e.g., pathogen) DNA. Current internal control procedures, however, which usually involve the introduction of a DNA fragment, are complex, time-consuming, and expensive. METHODS Sin...
