Which lab tests should be ordered in menopause?

There is a common frustration: a woman asks for "the menopause test" and discovers it does not exist. Gynecology and endocrinology guidelines are clear: in a woman over 45 with an irregular cycle and typical symptoms, the diagnosis of the transition is clinical. A lab test alone neither confirms nor rules it out, because in this phase hormones swing from one month to the next.

That does not mean labs are useless. It means they answer other questions, and those are worth a lot.

What the tests actually answer

• •FSH and estradiol. Useful when the diagnosis is in doubt: a woman under 45, atypical symptoms, or an evaluation for early menopause. Persistently high FSH with low estradiol closes the case. In the typical transition, a single isolated value can mislead.
• •TSH and free T4. Mandatory, because hypothyroidism mimics menopause: fatigue, weight gain, hair loss, low mood. Missing a thyroid problem because "it's just menopause" is a mistake that costs years.
• •Fasting insulin, glucose and A1C. Falling estrogen worsens insulin sensitivity, and metabolic risk rises after menopause. This is the phase to catch insulin resistance before it becomes diabetes.
• •Lipid panel. Estrogen was protective; cholesterol tends to worsen through the transition. A woman's cardiovascular risk moves to a new level here.
• •Vitamin D, calcium and bone health. Bone loss accelerates in the first years. Bone density scan according to age and risk.
• •Ferritin and B12 if there is fatigue, hair loss or poor memory: these are the raw materials that plummet alongside and confuse the picture.

The mistake at both extremes

One extreme orders too many tests and treats numbers, not the person. The other orders nothing because "menopause is normal". Both fail at the same point: they do not look at the whole. It is normal for menopause to happen; it is not mandatory to cross it sleeping badly, gaining weight and living in a fog, with nobody building the complete map.
