[QUOTE="Cataceous, post: 199026, member: 38109"] If there's no harmonization between the different testing methods then the units are virtually meaningless. A lab could say its free T results are in furlongs per fortnight and it wouldn't change anything as long as the reference range was in the same units. At present you can compare these free T measurements only to the reference range or to other results acquired using the exact same test. The reference range is different from the capabilities of the test. The standard definition for a reference range includes 95% of the normal population. This is the range that includes from two standard deviations below the mean to two standard deviations above the mean. It says nothing about the maximum possible value a particular testing method can measure. That must be stated separately. If your measured free testosterone is at twice the top of the reference range it means that only an exceedingly tiny fraction of men, if any, might naturally have such levels. [/QUOTE]
