For example - in 1930 testosterone normal level in the population is 10 units . So when you have a blood test the normal range is 8-12.
In 2020 the normal level is 4 units, so the normal range has been adjusted to 2-6
I hope I am making sense, and I really hope to get an answer. To me this makes no sense. For sure adjustments are made based on better science, but not because the population is becoming unhealthier?
