Between April and October 2020, we conducted serologic testing of patients with (i) signs and symptoms of COVID-19 who were repeatedly negative by RT-PCR (‘Probables’; N = 20), (ii) signs and symptoms of COVID-19 but with a potential alternative diagnosis (‘Suspects’; N =...
Meanwhile, the representations are further enhanced in a contrastive learning manner, discriminating the positive (orange arrows) and negative (blue arrows) pairs after being mapped by the projection network into the dp-dimensional space. The enhanced representations can promote more precise diagnostic ...
Coronavirus antigen test was performed in six patients, with all of them testing negative. SARS-CoV-2 infection was confirmed serologically by the detection of specific IgG and IgA in all 17 patients and also IgM in six patients, not before day 8 of the onset of symptoms. Conclusions:Our ...

A challenge with regard to misdiagnosis in countries working toward malaria elimination is that people with fever may pref- erentially undergo testing for COVID-19 and be sent home due to a negative result [29]. Another scenario is that pa...
RT-LAMP at RT-RPA, which are mostly applied for CRISPR-based SARS-COV-2 detection, required the incubation for 20–30 min at 62 °C and at 37 °C correspondingly, while for RT-PCR several temperature changes are needed as it is stated in the protocol. After the double-stranded DNA is...
Second, adherence to a pre-planned statistical plan is far better for confidence than any protocol deviations or modifications—for this precise reason: doubt can exist about the true motives. The sameSciencearticle discusses how because of the ongoing changes, Pfizer had stopped testing swabs to ...
But what we could see is its best used for example in any environment, depending on what your protocol is, to be able to test and be able to provide on the spot people with that negative entry card, that digital pass that shows “I’ve been tested” and now I can show that p...
