i understand it like that he tested negative on at least one test (which doesn't necessarily mean he's in the clear). 'undergoing tests' meaning that the doctors aren't ready to call it, testing is being continued.also:
"In medical testing, and more generally in binary classification, a false positive is when a test result indicates that a condition – such as a disease – is present, but it is not in fact present, while a false negative is when a test result indicates that a condition is not present, but it is in fact present."
