[QUOTE="Cataceous, post: 186655, member: 38109"] It's all talking about the same thing—how testosterone compares to estradiol, but the units are different. If I tell you it's 32 degrees outside you need to know if it's Fahrenheit or Celsius before you know if it's hot or cold. The different ways of defining the relative comparison of estradiol and testosterone are interchangeable, readily cross-converted. For example, E2/T as a percent is converted to the commonly used T/E2 ratio in US units by dividing the value into 10. For your number of 0.317% above, 10 / 0.317 = 32 (ng mL / pg / dL). It is also calculated directly from your test results: 1110 ng/dL / 35 pg / mL = 32 (ng mL / pg / dL). On this inverse scale your ratio is now on the high side of what's considered typical—more like 15-25. Reiterating: all that matters regarding these ratios is that people agree on which version is being used. Being familiar with these two common ones—and their normal values—is probably all you'll need. [/QUOTE]
