1.2 Diagnosis of perimenopause and menopause
1.2.1 Diagnose the following without laboratory tests in otherwise healthy women aged over 45 years with menopausal symptoms:
perimenopause based on vasomotor symptoms and irregular periods
menopause in women who have not had a period for at least 12 months and are not using hormonal contraception
menopause based on symptoms in women without a uterus.
1.2.2Take into account that it can be difficult to diagnose menopause in women who are taking hormonal treatments, for example for the treatment of heavy periods.
1.2.3Do not use the following laboratory and imaging tests to diagnose perimenopause or menopause in women aged over 45 years:
anti-Müllerian hormone
inhibin A
inhibin B
oestradiol
antral follicle count
ovarian volume.
1.2.4Do not use a serum follicle-stimulating hormone (FSH) test to diagnose menopause in women using combined oestrogen and progestogen contraception or high-dose progestogen.
1.2.5 Consider using a FSH test to diagnose menopause only:
in women aged 40 to 45 years with menopausal symptoms, including a change in their menstrual cycle
in women aged under 40 years in whom menopause is suspected (see also section 1.6).
