Not every man with ED has low T. But if these signs are present, you need to test your testosterone. It can be easily tested in your blood. You can get your total testosterone because total testosterone tests your testosterone that is free as well as the one that's bound to protein or albumin.

Free testosterone, exact hormone binding globulin or shbg.
