...As you say - in different words - it would be pretty sad for the "hostiles" when or if the day comes that completely reliable biomarkers are established (possibly not so far away, IMO) and they tested negative.. though some denial would then probably kick in (the test was wrong, wrongly administered, biased, only true for some not others etc) - the 100% former confidence in "professionals" that some of that group have previously expressed might rapidly vanish as quick as an eyeblink.
Cystic fibrosis is caused by more than 1,500 genetic mutations which also affect differences in CF severity. Not all such mutations were discovered, researched and validated at the same time, of course. In fact, researchers believe that the final number of mutations might include more. Until then, individuals with CF symptoms and their physicians treat the symptoms as if CF is present despite a lack of diagnostic evidence. Sounds a little like a possible future where all ASD diagnoses are re-examined.
In any case, I sympathize with those with any disease or disorder who were diagnosed at one time, but now aren't and face a rediagnosis.
