Perimenopause Fact Sheet: Can You Test for It?

Perimenopause Fact Sheet: Can You Test for Perimenopause?

Perimenopause can feel like a mystery. One day you’re fine, the next you’re bloated, moody, and awake at 3am wondering if you’re losing your mind. Many women ask me:

“Can I test for perimenopause?”

The short answer: there is no single test that can confirm perimenopause. But there are important facts to know.

What Is Perimenopause?

  • Perimenopause is the transition period leading up to menopause.
  • It usually starts in your late 30s or 40s and can last 8-15 years.
  • Menopause is confirmed when you’ve gone 12 months without a period.

Common Symptoms of Perimenopause

Every woman’s experience is different, but some of the most common symptoms include:

  • Irregular or heavier periods
  • Hot flushes and night sweats
  • Mood swings, anxiety, or depression
  • Sleep problems
  • Weight gain (especially around the belly)
  • Brain fog and poor concentration
  • Breast tenderness or migraines
  • Changes in skin, hair, or joints

Can You Test for Perimenopause?

This is where it gets tricky.

  • Blood tests (FSH, oestrogen, progesterone) can be run, but hormone levels fluctuate daily so one reading doesn’t prove much.
  • Thyroid and iron tests are often done to rule out other conditions that mimic perimenopause.
  • Age and cycle changes are usually the biggest clues.

Doctors may say your results are “normal,” but your symptoms may tell a different story. Hormones shift like a rollercoaster in perimenopause, so the best “test” is often your lived experience.

Where Testing Can Help

Testing is useful to:

  • Rule out thyroid disease, anaemia, or other health issues.
  • Provide baseline data before starting HRT.
  • Check other midlife health markers (cholesterol, blood sugar, vitamin D).

But  no test will tell you definitively that you are in perimenopause.

What Actually Matters Most

  • Track your cycle and symptoms month by month.
  • Pay attention to changes in your mood, sleep, energy, and weight.
  • Use blood tests to rule out other causes, not as the only answer.
  • Get support to manage your health through nutrition, exercise, and lifestyle strategies that work with your hormones.

My Own Experience

When I was 37, my blood work came back “normal.” The doctor said I was too young for perimenopause. Meanwhile, I was gaining weight, anxious, and couldn’t sleep. The test didn’t help me but tracking my symptoms and changing how I ate, trained, and recovered did.

That’s why I coach women through this stage. You don’t have to wait for a doctor to confirm what your body already knows.
