This past spring, after a telemedicine visit, I was sent to a Quest draw center in Los Angeles for a routine blood test. This required me to log into their appointment system with my email, and I've gotten regular direct marketing since.
Here's a pitch to come in and get a COVID 19 Antibody Test - for $119. Quest doesn't require your doctor's prescription, it looks like they will arrange an e-prescription for $9.30 as part of the package.
Your antibody test will provide results in 3-5 business days. I've clipped the advertising, as seen on my iPhone, below.
By the way, unrelated, a physician-wellness clinic a few blocks from my house has an advertisement plaque on the sidewalk for antigen test, While-U-Wait, $95.
