Testosterone: What Affects The Test

What Affects the Test
Reasons you may not be able to have the test or why the results may not be helpful include:
- Taking medicines such as estrogen (including birth control pills), testosterone, corticosteroids, digoxin (Lanoxin), spironolactone (Aldactone), or barbiturates.
- Having hyperthyroidism. This can raise sex hormone binding globulin (SHBG) levels. Hypothyroidism can lower SHBG levels.
- Taking medicines to treat prostate cancer.
- Taking medicines that raise prolactin levels, such as certain seizure medicines.
