Till now there are only two technique to detect SARS-CoV2 among COVID-19 Patients: real time PCR and Rapid test
Good evening Dr. Hussein
Not it is not, due to it will give negative redults, as during this period the IgM still not detected yet.
Therefore, PCR will be beneficial more at this period.
Thanks

rapid test is one of multi tests to detect corona virus infection
No. As no Abs appear at this time, So the gold standard is RT-PCR at this period.
Regards
No it useful in this period because in this period there is no antibodies alleviated
Hi, Doctor
Widow periodThis is the time between original infection and the appearance of Detectable antibodies to the virus, so the test is not useful in this period
Dear Dr..
I think its both useful and not ..
Its useful since we have a huge number of suspected persons so its will make it easy for fast detection at least in iraq .
and not since we the human differ by our immune response .
Hi Dr. Hussein
This test is not useful in this period Widow period, because it is the time between original infection and the appearance of Detectable antibodies to the virus.

It's not useful in window period and the repid test give negative result, cuz in this period the antibody (IgM) still not apparance/detected yet.
Hi dr.
Not useful through this period, we took this information today.
Yes
But the determination of the company because companies differ in qualityز
No , because these tests depend on detection of antibodies. During window period there're no detectable antibodies
It was deferent and not fix in all patients according to the number of viruses that introduce and the strength of Immunity and virus strains but it can diagnosis the Abs after 7 days from the infections and in small levels of Abs.
- yes, the SARS-CoV2 Rapid test is useful to detect COVID-19 during the Window period because The window period is important to epidemiology and safe sex strategies, and in blood and organ donation, because during this time, an infected person or animal cannot be detected as infected but may still be able to infect others.
May be the determination of the company because companies differ in quality..
Rapid test cannot be detected COVID-19 during the window period,
Rapid test depend on IgG and IgM which not present during window period
NO, because SARS-CoV2 specific antibody in this period not raised enough to be detectable
Combating the coronavirus pandemic: In just six weeks, Bosch developed a rapid test that can detect a SARS-CoV-2 coronavirus infection in patients in under .
the test gives large percent of false positive results and false negative results
Methods based on antibody detection are not and can not be used to confirm diseases! The accuracy of rapid tests for covid-19 are not yet determined. Their sensitivity and most important their specificity remain obvious. PCR remain the only diagnostic test available so far.
Antibody tests are not as good as PCR for diagnosis but it can be useful to identify asymptomatics vs healthy and can also supplement the mainline confirmatory tets. So in my opinion antibody detection can help in mass surveillance of Covid19 that is actually needed.
Dear Dr. in this RE open question we attempt to analyse the Lombardia dramatic event in mortality rate, but now, also for other Europea key areas (Madrid, Catalonia, London, Netherlands). Some work hypothesis are: oro-fecal transmission; Diamond Princess passengers return as spreaders (according to insufficient quarantine and positive intestinal tests but negative in nasal-oral tests); additional animal reservoirs; urban-river effect.

Dmitry Nikolaenko can you please stop spamming questions with your preprint, especially when it does not address the question in hand.
If you want to get people involved in your work open your own discussion on Researchgate please.
During the window period, nop, that is just a limitation for a serologic test.
NO, because SARS-CoV2 specific antibody in this period not raised enough to be detectable and that is just a limitation for a serologic test
May be, but not sensetive as molecular techniques (RT_ pcr) and chest CT picture.
May be good for detection of some cases specially asymptomatic
