Clinical laboratories produce test results that support the diagnosis, prognosis, and patient treatment. Test results must be relevant, accurate, and reliable for patient care. International bibliographic data estimate that approximately 62.0% of the errors made in clinical laboratories are due to errors during the pre-analytical stage. This chapter presents a failure modes and effects analysis (FMEA) to analyze potential failure risks within the pre-analytical phase and classify them according to severity and likelihood. FMEA allows molecular laboratories to lower costs and drive better outcomes through high-quality nucleic acid extraction, sensitive detection, and accurate quantification. RT-PCR technology continues to be the gold standard for the clinical detection of SARS-CoV-2 RNA in individuals suspected of COVID-19. It is essential to use highly sensitive assays to detect active infections and reduce the likelihood of false-negative results. |
