What belongs here
Longevity becomes useful when objective measurements help establish a baseline, identify priorities and guide an appropriate next step. The test itself is not the outcome.
Well+ separates diagnostics from general wellness treatments. A clinic belongs here when it offers meaningful screening, testing, medical imaging or clinician-led assessment—not because it also offers IV therapy, red light, HBOT or recovery treatments.
Results should be interpreted in context. Screening can produce false-positive, false-negative or incidental findings, so more tests are not automatically better and concerning symptoms should follow an appropriate medical pathway.
