Hello and hope you are doing well.
The normal range of testosterone in males is 300 -1,000 ng/dL and in females it is 15 - 70 ng/dL.The normal ranges vary among laboratories. Few labs may use different measurements or test different specimens. It is best to talk to your doctor about the interpretation of test results. Write to me again with more queries.
Best wishes and regards!
Thanks for your reply. Since I first wrote, blood tests revealed a level of 250 or so, low enough to be a possible cause of my tiredness and general lethargy. Before getting a testosterone thingummy implanted subdermally, I just had an MRI of my head to make sure a benign tumor (2 of 3 blood tests for the possibility were off) is not messing with my pituitary.
Thanks for your help. I sure hope the MRI doesn't reveal anything.
