8)What is the Limit of Detection (LoD) of your test for detecting SARS-CoV-2? The LoD for throat swab is 150 viral copies/mL. For BALF, the LoD is 100 viral copies/mL. 9)What is the turnaround time of your test when the MGISP-960RS automated sample preparation system is used?
COVID-19 is a multi-system infection with emerging evidence-based antiviral and anti-inflammatory therapies to improve disease prognosis. However, a subset of patients with COVID-19 signs and symptoms have repeatedly negative RT-PCR tests, leading to treatment hesitancy. We used comparative serology...

Most laboratories generate their COVID-19 test results through a molecular testingprocesscalled reverse polymerase chain reaction, or RT-PCR, that has beenused for yearsto diagnose a variety of diseases. A patient gets tested with a nasal or throat swab, or in some cases provides a saliva samp...
Viral RNA Extraction MagLEAD 12gC automated extraction platform (Preci- sion System Science, Chiba, Japan) was used to extract SARS-CoV-2 RNAs from 200 µL of nasopharyngeal and throat swabs. Extraction was performed according to the manufacturer's instructions. Viral RNA was eluted with 100 ...

Other seven patients who diagnosed with COVID-19, after one month of treatment and quarantine, the throat swab showed a negative result by the rRT-PCR protocol because only the N gene was detected. However, these samples were positive results by the Cobas SARS-CoV-2. Rest five discordant ...
while AdV was detected only in BAL and PIV2 and hMPV only in throat swab. In contrast, hRSV was the most common virus detected in children, followed by EVs, influenza A virus and CoV NL63. However, the small number of samples/patients does not allow us to draw any epidemiological concl...
All 46 throat swab samples from 46 confirmed inpatients were detected by qualitative real-time RT-PCR directly, as well as after heat inactivation. Heat-Inactivation has significantly influenced the qualitative detection results on clinical samples, especially weakly positive samples. The results indicate...
A second swab was obtained by having the child suck on the swab in the anterior mouth for 30 seconds and a third swab was obtained from the posterior pharynx. PCR was performed on these two additional swabs using the cobasLIAT (Roche) system according to the manufacturer's instructions. ...
