In the past, we have received "offers" to have a home visit by a healthcare "professional".

Today, I get an envelope from a company called bioQ that wants me to take a blood sample and send it to them. They want to advise me if I have diabetes. Sample kit included.
Claim to be affiliated with Anthem. Sure I'll send you a blood sample - from the dog

Hah! I think they might catch on, though...
