Some researchers have suggested that these failures in SARS-CoV-2 91 detection are related to multiple pre-analytical and analytical factors, such as lack of standardisation 92 to collect specimens, the time and conservation of samples until to be received in the laboratory, 93 the use of non-adequately validated assays, contamination during the procedure, insufficient viral 94 specimens and load, the incubation period of the disease, and the risk of active recombination and 95 mutation [14, 16] . 96
