Estradiol vs LH: Key Differences Explained
Compare Estradiol and LH to learn which marker is more relevant for health assessment.
Why Compare Estradiol and LH?
Comparing Estradiol and LH is crucial because they are often used to assess similar yet distinct health conditions. Understanding their differences helps in selecting the right test and interpreting the results accurately.
Estradiol vs LH: Which Biomarker Matters?
Estradiol and LH are essential biomarkers used to evaluate different health conditions. Knowing when and how to interpret these biomarkers can significantly impact clinical decision-making.
Quick Comparison Table:
Biomarker | Purpose | Ideal Range | When to Test | Key Differences |
|---|---|---|---|---|
Measures estrogen levels | 15-350 pg/mL | Monitor reproductive health | Primary estrogen in non-pregnant women | |
Stimulates ovulation and testosterone production | 1-20 IU/L | Evaluate fertility and hormonal balance | Peaks during ovulation |
Key Takeaways:
Estradiol rises before ovulation; LH spikes to trigger egg release.
Their timing is critical — poor coordination may signal cycle dysfunction.
Monitor both for ovulation assessment and reproductive planning.
