Which would effectively be the same as saying… 160-310 pg/ml, correct? If one wanted to convert to pg/ml they could use Quests reference range of 46-226 pg/ml to compare it to. IE: My free T is 53 Pg/ml which is the same thing as 5.3 ng/dl. If i converted to ng/dl and wanted to compare ng/dl values I would have to compare it to a reference range that was based on nano grams per deciliter. Such as lab corp or Tru-Ts reference range
If the average person had to drink 1 gallon of water per day to be in a healthy range. wouldn’t that be the same as saying 128 fl oz… Units can be converted but reference ranges will have to be switched to match those units.
I could be way off here, but that is how we learn and grow by questioning and obtaining knowledge.
