This is the first authorized in the united states it works with chemical compounds associated with covid-19 infection in breath samples. and it can provide results in under three minutes. now, this breath test is authorized for use in doctors' offices, mobile testing sites, hospitals. it's not authorized for at-home use. but who knows where the technology is heading. maybe that can be a development in the future. but now for now, official dr. jeff sherman said in this statement, today's authorization is yet another example of the rapid innovation occurring with diagnostic tests for covid-19. a...

That's the percent of negative samples the test correctly identified. so it is comparable to the rapid ant jen tests. if you test positive, you still need to get that nasal swab pcr test to confirm the positive test results. the breath test is shown to turn results in three minutes. it detects a compound associated with covid-19 in breath samples. so that's the technology. that's what we know. >> so to be clear, despite the strong findings, this new breathalyzer from inspect ir does not completely replace the nose swab test. >> that's right. this is not a replacement. it is more lying having a...

The tools to combat them are not. so again health officials are saying that this is an effort to make people aware and the tools we have, vaccinations for instance, play a role in helping with protection. health officials also noted that with these subvariants, there is a 23% to 27% growth advantage above the ba.2 variant. so the growth advantage is what is being looked at very closely, how quickly this spreads, how quickly it is growing. >> and jacqueline, the fda just authorize the first covid breath tests. how do those work. >> that is right. this breath test really analyzes breath samples ...

We found that the destruction continued on for the entire duration of the 6—month mission of these astronauts, and this high rate of destruction is not sustainable. so, we found also robust signs of an increased production of red blood cells to match the destruction so, unsuspected to us, we find there is a higher level of turnover, loss of red blood cells produced and destroyed, and that increased turnover is happening in the background and we did not know about that — that is one of the main findings of the study. and how did you get the samples with these astronauts? did it mean loads o...

With these astronauts, did it mean and loads of blood tests, or did you do that in a different way? ok, so we used some unique methods for that. and that involves collecting breath samples from astronauts. so we sent to space a kit, a breath kit that the astronauts will prepare the day before, and the next morning they will blow into a series of tubes, and then transfer the air from a plastic bag into a metal canister, and that metal canister was sturdy enough to be sent back to earth and back to our lab for analysis. that is really fascinating. crosstalk. just a final question if i may, what ...
