Most of the problem with the reference ranges is that they are usually just intended to reflect what 95% of the reference population will have. That’s much easier to measure than the range which indicates good health.
There isn’t much incentive for any authority to establish guidelines for healthy ranges. So too many people end up equating “normal” results with good results, because normal is what gets quantified, and is usually what is reported on test results.
