It’s scarily common in medicine for doctors to start specializing in diagnosing certain conditions with non-traditional testing, which leads them to abnormally high diagnosis rates.

It happens in every hot topic diagnosis:

When sleep apnea was trending, a doctor in my area opened her own sleep lab that would diagnose nearly everyone who attended with apnea. Patients who were apnea negative at standard labs would go there and be diagnosed as having apnea every time. Some patients liked this because they became convinced they had apnea and frustrated that their traditional labs kept coming back negative, so they could go here and get a positive diagnosis. Every time.

In the world of Internet Lyme disease there’s a belief that a lot of people have hidden Lyme infections that don’t appear on the gold standard lab tests. Several labs have introduced “alternate” tests which come back positive for most people. You can look up doctors on the internet who will use these labs (cash pay, of course) and you’re almost guaranteed to get a positive result. If you don’t get a positive result the first time, the advice is to do it again because it might come back positive the second time. Anyone who goes to these doctors or uses this lab company is basically guaranteed a positive result.

MCAS is a hot topic on TikTok where influencers will tell you it explains everything wrong with you. You can find a self-described MCAS physician (not an actual specialist) in online directories who will use non-standard tests on you that always come back positive. Actual MCAS specialists won’t even take your referral from these doctors because they’re overwhelmed with false cases coming from the few doctors capitalizing on a TikTok trend.

The same thing is starting to happen with CVD risks. It’s trendy to specialize in concierge medicine where the doctor will run dozens of obscure biomarkers and then “discover” that one of them is high (potentially according to their own definition of too high). Now this doctor has saved your life in a way that normal doctors failed you, so you recommend the doctor to all of your friends and family. Instant flywheel for new clients.

I don’t know where this author’s doctor fits into this, but it’s good to be skeptical of doctors who claim to be able to find conditions that other doctors are unable to see. If the only result is someone eating healthier and exercising more then the consequences aren’t so bad, but some of these cases can turn obsessive where the patient starts self-medicating in ways that might be net negative because they think they need to treat this hard to diagnose condition that only they and their chosen doctor understand.
