I am 25 and had my testosterone levels tested for concern. He did not feel my symptoms were related enough, but gave me a testosterone test and couple others off blood work. He told me my results were normal with a total test of 239. He said the range they uses is 179-756. Everywhere I have read this seems low. Can my total test number be different then others that I have read about for this to be considered "normal"? Would like some insight on this.
