Holy c, I simply walked into my GP, asked for a number of blood tests. Cost = £0. The GP asked me whether I wanted anything else tested too. Couldn't think of anything else. Isn't the NHS great? Well, most of the time. I've been investigating reasons for fatigue. I did some research and then asked the GP to test my blood's E, T, thyroid and ferritin levels.
luna nyan, how can 15 ng/dl be an average male T level?
My T level is <11.5 ng/dL (<0.4 nml) and less than menopausal women.
