1. Seek the advice of  your General Practitioner, and tell him/her your symptoms, which are the most important factor in establishing a diagnosis.

2. A blood profile may be suggested, which needs to include not just total testosterone, but  a test for free active testosterone, which is best obtained in the form of the Free Androgen Index (FAI) by calculation from the Sex Hormone Binding Globulin. Where this is not available, the free testosterone and the free-and-weakly bound testosterone can be used. The symptoms you are suffering are more important than the lab data, as accepted reference ranges vary widely.

If you are over 50, it is advisable to include a Prostate Specific Antigen test,  and is mandatory before and after starting on testosterone treatment.

3. An interactive on-line questionnare to assess the severity of your condition from your symptoms has been developed and validated by Prof. Lothar Heinemann, which may help determine whether you are suffering from Androgen Deficiency.
