Yesterday a Bora rider tested positive, forcing the team to withdraw from the Bretagne Classic, then tested negative just hours later. Statement from Bora "It is reasonable to conclude that this was a false positive test result."¿False positive? The test looks for the specific genetic material of the virus. It's perfectly possible to test positive and have no symptoms of illness. And it's normal to test positive on a day and negative one week after. All this has been known for months.
I'm torn between the reports of Hospitals and Medicine Schools and those of Cycling News
You say it's normal to test positive one day and negative one week after, but hours later? And he tested negative in the days before the race. The testing system needs to be changed (A and B samples?) before the Tour starts.
