The First Step: Rule Out Pregnancy
Before diving into more complex tests, it's crucial to rule out pregnancy as a cause of missed periods. This is typically done with a serum hCG test, which is more sensitive than home urine tests. Once pregnancy is excluded, other potential causes can be explored.
Hormonal Tests Unveiled
Key hormonal tests include measuring FSH, prolactin, and TSH levels. High FSH levels suggest ovarian insufficiency, while elevated prolactin can indicate hyperprolactinemia. These tests help doctors determine if the issue lies within the ovaries, pituitary, or thyroid.
When Imaging Comes Into Play
If hormonal tests suggest pituitary issues, an MRI may be needed to look for abnormalities like a pituitary tumor. This imaging helps ensure there's no structural cause for the amenorrhea, such as a tumor affecting hormone production.
