ABSTRACT

Objective:

To compare and analyze 7 new coronavirus nucleic acid detection kits and 5 nucleic acid extraction methods.

Methods:

After extracting nucleic acids from 44 positive coronavirus clinical samples, 7 SARS-CoV-2 nucleic acid detection kits were used for RT-PCR amplification experiments to compare the positive rate and Ct value;33 new coronavirus positive clinical samples were selected to compare the acid extraction methods. Five different nucleic acid extraction methods were used to extract the samples, and then RT-PCR amplification experiments were performed to compare the positive rate and Ct value.

Results:

The brand A nucleic acid extraction kit had the highest positive rate and the lowest rate of missed detection;comparison of nucleic acid extraction methods showed that the manual column extraction method had the highest positive rate, followed by the magnetic bead extraction method, and the one-step extraction method had the highest missed detection rate.

Conclusion:

The detection capabilities of the SARS-CoV-2 detection kits are uneven, so evaluation work needs to be done before the selection of the kit. The manual column extraction method showed best extraction efficiency but took a long time. Because of the possible combination with the automatic nucleic acid extraction instrument, the magnetic bead extraction method had a high extraction efficacy, which might be suitable for use in the ex- traction of large batches of samples. Although the one-step extraction method was easily operable, the method had a high missed detection rate, so this method was not recommended for clinical use.
