What Affects the Test

Reasons you may not be able to have the test or why the results may not be helpful include:

• Hormone replacement therapy after menopause.
• Birth control pills, patches, or rings and other forms of hormonal birth control.
• Having a test that uses a radioactive substance, such as a bone scan, within 1 week before the test.
• Medicines, such as clomiphene (Serophene, Clomid) or steroids (for example, prednisone).
• High levels of sugar in the urine caused by diabetes.
