I'm taking a testosterone test via blood on Monday for free and total testosterone. I'm wondering, is there anything I should do or not do prior to taking the test to get the best and clearest reading? I already know taking it in the morning is the best time to take it, since that's when it will be at it's highest, but what else should I do or not do? Will not eating prior to taking the test help? Thank you.
These are some factors that alter the magnitude of the reading. However, there is nothing you can do to get a "clearer" reading. Just be yourself :) If you are interested in any particular reference, I might be able to dig it up, however, googling testosterone will give you plenty more ideas about what affects testosterone levels.
