Diagnosing postmenopause is usually based on your symptoms and the fact that you’ve gone 12 months without a period. In most cases, you won’t need any tests. However, if you're younger and showing signs of menopause, your doctor might suggest a blood test to confirm.
Your doctor will likely ask about your health history and symptoms, like when your last period was, to help determine if you're in postmenopause. This can often be done without needing a blood test.
If necessary, your doctor might recommend a blood test to measure hormone levels like estradiol and FSH. After menopause, your body produces more FSH, while estradiol levels decrease, which helps confirm if you’re in postmenopause.
