Clinical epidemiological applicability of real-time polymerase chain reaction for COVID-19 [PDF]

open access: yesOsong Public Health and Research Perspectives, 2022
Objectives Real-time polymerase chain reaction is currently used as a confirmatory test for coronavirus disease 2019 (COVID-19). The test results are interpreted as positive, negative, or inconclusive, and are used only for a qualitative classification ...

Real-Time Polymerase Chain Reaction: Applications in Diagnostic Microbiology

open access: yesInternational Journal of Medical Students, 2013
The polymerase chain reaction (PCR) has revolutionized the detection of DNA and RNA. Real-Time PCR (RT-PCR) is becoming the gold standard test for accurate, sensitive and fast diagnosis for a large range of infectious agents.

On joint maximum-likelihood estimation of PCR efficiency and initial amount of target [PDF]

open access: yes, 2007
We consider the problem of estimating unknown parameters of the real-time polymerase chain reaction (RTPCR) from noisy observations. The joint ML estimator of the RT-PCR efficiency and the initial number of DNA target molecules is derived.

Enhanced analysis of real-time PCR data by using a variable efficiency model : FPK-PCR [PDF]

open access: yes, 2011
Current methodology in real-time Polymerase chain reaction (PCR) analysis performs well provided PCR efficiency remains constant over reactions. Yet, small changes in efficiency can lead to large quantification errors. Particularly in biological samples,
