LitCovid-PD-MONDO
Initially, the need for elaborate biosafety precautions and inconsistent recommendations for their application across regions severely hampered COVID-19 testing. Although these continue to evolve, current recommendations in Canada and the United States acknowledge that nonpropagative work for molecular testing may be performed in containment level 2 conditions found in routine diagnostic laboratories and provide specific guidance on diagnostic testing of specimens conducted outside a biosafety level 2 laboratory, such as rapid respiratory testing performed at the point of care (67) .
