RE:100% specificity and selectivity in assymptomaticsWell, kinda. 3/3 is 100%, but if they had tested a handful more and missed the fourth then you're at 3/4 and 75%.
When you do the maths the symptomatic data isn't great frankly. The FDA position on this dataset will be interesting.
But, having said that picking up the 3 out of 40 positive asymptomatics is a good result. This really is a rollercoaster stock!
