false positive

So before the square dance that we had last weekend, we were supposed to covid test. Ken had a cold earlier, for which he had rapid tested and gotten a negative result. And then he felt better, but just in case he did the Cue test, which is one of those molecular tests, in addition to rapid test. Well, it was positive! Dang. So I tested with Cue, and I was negative, and also negative on rapid test, so I went to the dance. He did not go. He tested with Cue again the next day and was negative. He's been negative rapid test all along. So we think we might have had a false positive. Which is sad, because he missed a great dance.
