I'm sorry to hear that you're dealing with that. If you're comfortable doing so, I wonder if you could share more details about how increased testing is involved? Thank you.
Not OP, but generally if you increase testing, you find more instances of disease, especially for diseases with lower/hard to gauge impact (ones that people may not have gone to the doctor for in the past).
Also not OP, but I recently got diagnosed with (another) autoimmune disorder solely because a single doctor twisted my arm into getting some unpleasant tests done. Turns out I have Crohn's disease and not just an unusually capricious stomach. (Also, thankfully, turns out Crohn's symptoms get significantly better with treatment.)
But if I hadn't been willing to power through the time and money and discomfort of getting tested, I probably would've remained undiagnosed for years. I'm thankful we caught it now and not before things got bad enough to land me in the hospital.
