Testing for Menopause
Menopause should be diagnosed clinically based on 12 months of amenorrhea in women aged 45-55 years without requiring laboratory testing. 1, 2
Clinical Diagnosis Without Laboratory Testing
The diagnosis of menopause is fundamentally clinical and does not require hormonal testing in most circumstances. 1, 3
- Menopause is defined as 12 consecutive months of amenorrhea in the absence of other pathological causes, occurring at a mean age of 51 years (95% between ages 45-55). 1, 2
- Laboratory tests such as FSH and inhibin B are not accurate enough by themselves to rule in or rule out perimenopause and should not be relied upon for diagnosis. 3
- The diagnosis should be made based on menstrual history and age alone. 3
When to Consider Testing
Laboratory testing may be considered in specific situations:
- Women under age 45 with suspected premature ovarian insufficiency who present with amenorrhea and menopausal symptoms. 1
- Women with prior chemotherapy or tamoxifen use where the standard 12-month amenorrhea definition may not apply. 1
- Women with surgical removal of ovarian tissue (though menopause is definitional in this case). 1
If testing is performed, elevated FSH (LR+ 3.06) and low inhibin B (LR+ 2.05) support the diagnosis, but neither is sufficiently accurate alone. 3
Initial Assessment of Perimenopausal Symptoms
For a woman presenting with hot flashes and night sweats:
Confirm Symptom Characteristics
- Hot flashes and night sweats are the most reliable clinical indicators (LR+ range 2.15-4.06 for hot flashes; LR+ 1.90 for night sweats). 3
- Determine frequency, severity, and whether night sweats are drenching enough to require changing bedclothes. 4
- Self-assessment of being in the menopausal transition has moderate accuracy (LR+ 1.53-2.13) and the strongest negative likelihood ratio (0.18-0.36). 3
Evaluate Impact on Quality of Life
- Use standardized scales like the Greene Scale to establish symptom range and severity. 5
- Consider menopause-specific quality of life tools such as MENQOL to evaluate impact on daily functioning. 5
- Assess for associated symptoms including vaginal dryness, dyspareunia, sleep disturbance, mood changes, and cognitive dysfunction. 5
Assess Patient Goals and Expectations
- Determine what the patient wishes and expects from intervention, as many women may find a 50% reduction in symptom severity acceptable. 1
- Some women may primarily be seeking information rather than pharmacological treatment. 1
Identify Modifiable Factors
- Evaluate lifestyle and environmental triggers such as spicy food, overheating, anxiety, smoking, and obesity, which may exacerbate hot flashes. 1
- Consider having patients keep a hot flash diary to identify personal triggers. 1
- Recommend exercise, achieving healthy weight, and smoking cessation, as hot flashes may be more severe in overweight women and smokers. 1
Common Pitfalls to Avoid
- Do not order routine FSH or estradiol levels in women aged 45-55 with typical menopausal symptoms and amenorrhea, as the diagnosis is clinical. 3
- Do not assume all symptoms are menopause-related; some may be due to aging or other psychological disorders. 5
- Do not overlook the need to counsel young women with amenorrhea about potential fertility, as they may still become pregnant despite irregular menses. 1
- In women with prior breast cancer or on endocrine therapy, recognize that vasomotor symptoms may be more severe than in women without cancer treatment. 1
