Yes, there are laws now. I edited my comment to mention that. Outside the US, labs are still a goldmine of data: time indexed numerical value that are used by providers to decide medical interventions. Except medical record or insurance history, you can't get any better than labs! Still I noticed in the US that labs selling directly to clients (like private md labs, only in some states) insist that the patient provide an accurate phone number. Given how phone numbers are used in the industry, I think they may want to keep the database accuracy for "future uses" when the law will change.
