What hormones should be checked for a 40 year old woman?

For a 40-year-old woman, key hormones to check include estradiol and progesterone to assess reproductive health, especially if she experiences irregular menstrual cycles or symptoms of perimenopause. Thyroid hormones (TSH and free T4) are also important to evaluate for thyroid function. Additionally, checking cortisol can help assess adrenal function, and insulin levels might be relevant for metabolic health. If there are concerns about bone health, levels of parathyroid hormone and vitamin D should also be considered.
