The two regions are not differentiated; amplification of either or both regions is a presumptive positive (detectable) test result and amplification of neither target results a negative (non-detectable) test result. Positive: Viral RNA is detected by NAT and this means that the patient is confirmed to have COVID-19 infection. • A more reasonable cutoff is Ct 30-35 or even Ct <30. Radiology 2020, :200432.

It may be that the test detected antibodies to a coronavirus closely related to the COVID-19 virus or that the test quality was flawed. Specimen Requirements: 4 mL Lithium Heparin plasma. Genomic or molecular detection confirms the presence of viral DNA. PCR manufacturers typically remind the users that “the detection result of this product is only for clinical reference, and it should not be used as the only evidence for clinical diagnosis and treatment[3]” and “designed for the specific identification and differentiation of the new coronavirus (SARS-CoV-2) in clinical samples from patients with signs and symptoms of Covid19”.
