 And then for me a big red flag, probably the biggest red flag was when we were doing this for the syphilis test. And I was doing what they called precision testing. So I ran the same sample over and over to see how much variation there was. And I found that at our cutoff level, there was a 43% coefficient of variation. So the standard deviation was 43% of the expected value, or the mean, which is enormous. And then we ran samples that were known to be positive for syphilis. And the first time we did that, we only got 65% correct. So we said, okay, that's not good. Let's try that again. And then we got 80% correct. And then we did this other test called finger stick versus venus, where we would actually collect samples from within theranos, from ourselves and from our coworkers. We would get the finger prick, we would get the venus straw, we would test them both and compare the results to make sure that you could actually do a finger prick for this. And a ton of us tested positive for syphilis. And I remember the manager of our lab just going, guys, it's not impossible. I guess it's not impossible, but if it's plausible, then we should maybe send out like a company wide email or something, but obviously no one took that seriously. So that was a huge red flag. Yeah, the syphilis test was definitely for me like the big, the big kind of like wake up call.
