Collection of a sample could generously be considered a medical "procedure" done on a person. But if a sample has already been collected for other purposes, testing said sample for an additional purpose can't be even generously said to be a medical procedure done on a person. The lack of informed consent as to what will happen with a collected sample is the thing. It's also incredibly stupid, as without informed consent a person can't think to tell the collector that they've recently eaten a poppyseed bagel, and thus their results will be tainted.
