Getting Blood Work Done
I have a question about blood work. I am going to get my blood work done on monday and was wondering if anyone knew the difference between free and total testosterone? If so do you know how sexual activity before the test will effect them? I was told not to have sex a day before the test. Any help would be appreciated. Thanks for your time.
