Hello I am a new member and I have a question I would like to ask. I had my toal testosterone level checked for the first time by my dr. The range on the test was 175 to 740. My test was 386. My buddy had his tested and the range for his test was 350 to 850. My question is, are there different ranges for these tests? What I am wondering is if I was tested the same place his was, would my testosterone level be higher because the range was different? I was also tested about 4:30 in the afternoon and I have heard that this can affect the level. But how much would this affect my level? I went to my uralogist and he said that it does depend on what machine they use to test so there are different ranges. Is this true or is he just feeding me a bunch of crap? Thanks in advince for all the answers.
