You don’t have to send your DNA anywhere to test yourself. The tests you can get for free or OTC are in-home tests that don’t require sending results anywhere.
It seems to me that it would have been useful to know if you’d had it - having had it should confer a level of immunity and at least a certain level of reassurance.
I was referring to the article, where they invite anyone who thinks they are a superdodger to send them DNA for sequencing.
Then you’ll end up in a lab somewhere after your horrible accident.
I am well aware of OTC anti-body tests.
