@DAlperovitch @michaelmina_lab @moskov @Robin_Quon @AbbottNews If it can detect a smaller amount, in theory it may still work. There can't truly be 'none' in the upper airway if you are breathing it out. But no data on this of course.
@DAlperovitch@michaelmina_lab@moskov@Robin_Quon@AbbottNews如果它能检测到少量，理论上它可能仍然有效。如果你在呼气，上呼吸道不可能真的没有。当然，没有这方面的数据。
