So, in order to avoid confusion : please understand that what I am writing below is written out of interest, and the desire to be able to understand more about what I am writing about .Please refrain from taking it personal, clasifying it as "AntiMyNation", "AntiCapitalism" or any other nonsense . Try to understand that I am interested in FACTS, and do not care about any sentiment re. the above mentioned .
Quick tests as well as quick antiboy tests could be really good news, and could well proove to be a game changer . But what I am really interested in for these tests is
- precison
- sensitivity
- failure rate
of those tests . Did some searches yesterday re antibody tests, and just now for the announced quicktest by Abbott . Could not find the Information really .
Please understand me here . I am interested in whether those tests are actually RELIABLE, and therefore really helpfull .
For the rather quick, serological antibody tests which were reported yesterday (?) to roll out, the FDA
does not intend to object to the development and distribution by commercial manufacturers” of these tests, provided they meet a number of criteria, including qualifying the results of their reported test results with the following information:
- This test has not been reviewed by the FDA.
- Negative results do not rule out SARS-CoV-2 infection, particularly in those who have been in contact with the virus. Follow-up testing with a molecular diagnostic should be considered to rule out infection in these individuals.
- Results from antibody testing should not be used as the sole basis to diagnose or exclude SARS-CoV-2 infection or to inform infection status.
- Positive results may be due to past or present infection with non-SARS-CoV-2 coronavirus strains, such as coronavirus HKU1, NL63, OC43, or 229E.

On Thursday, the FDA amended their emergency policy around diagnostic testing for SARS-CoV-2, the novel coronavirus that causes COVID-19. Following on a
techcrunch.com
this to me amounts to "worse then useless" . Please, please, please base any discussion on this on FACTS .
As another caveat, there have been voices during the past week mentioning that - just as with almost everything else urgently needed at the moment - also the chemicals needed for PCR tests are running low, since there are only a few suppliers for some of them globally . Now, if the new tests newly announced are using different (re)agents, that would be reassuring .
