Estradiol deficiency occurs when the body produces insufficient levels of estradiol, a primary form of estrogen. This hormonal imbalance can significantly impact physical and emotional well-being, affecting everything from energy levels to bone health.
This blood test directly measures estradiol hormone levels in the body. Low levels can indicate deficiency and help explain symptoms such as fatigue, depression, hot flashes, and decreased sexual desire. Early detection is crucial as long-term estradiol deficiency can lead to serious complications like osteoporosis.
Because symptoms of estradiol deficiency can overlap with other conditions and vary widely among individuals, a definitive diagnosis requires direct measurement of estradiol levels in the blood. This ensures accurate assessment and appropriate treatment planning.
Estradiol levels naturally fluctuate based on factors such as menstrual cycle phase, menopause status, and age. Your healthcare provider will interpret your results in the context of your symptoms, medical history, and other relevant factors to determine if treatment is needed.
