This Estrogen Test measures the amount of estrogen in the blood. Present in both women and men, estrogens are the hormones behind female sexual development and function. Normal levels can vary depending on age and, in the case of women, menstrual cycles and pregnancy. Our Estrogen Test will call attention to abnormal estrogen levels, clearing the way for treatment options.

How Our Estrogen Test Works

For our Estrogen Test, simply place your order online and stop by one of our 4,000+ nationwide testing facilities at your convenience (no appointment required). A member of the center’s staff will collect a small blood sample at which point your part of the process is done. The sample collection itself takes only a few minutes and most patients are in and out and about their day in under a half-hour. From there, your sample will be processed in a CLIA-certified laboratory and in as little as 24-72 hours, you’ll have full results regarding your levels of estrogen.

Estrogen Fluctuation Symptoms

Those who experience abnormal levels of estrogen often experience the following common symptoms.

Abnormally high levels of estrogen may cause:

  • Irregular periods
  • Dense breast tissue.1

Abnormally low levels of estrogen can be associated with:

  • Menopause
  • Postmenopause
  • Reduced sex drive
  • Bone density loss
  • Weight gain
  • Trouble sleeping.2

This is not an exhaustive list but can be indicative that something may be off with your hormone levels.

How to Interpret Your Estrogen Levels

Delivered via our secure online portal, your results will provide your quantifiable result and reference range. The chart will include a column that declares in plain language whether your estrogen is in the normal range or if it is “flagged”. If your results are flagged, that can be interpreted as a potential hormonal imbalance. Higher levels than normal may indicate cirrhosis, early puberty, or a tumor.3 Lower levels of estrogen may suggest menopause, primary ovarian insufficiency or other complication. However, pre-existing conditions such as anemia, kidney disease or high blood pressure have been known to influence estrogen levels.4 If you should receive abnormal results, consult with your doctor for next steps.

Estradiol vs Estrogen Test

Although estradiol is a form of estrogen, it is just one of three types of estrogen. An estradiol test is specifically targeted at providing comprehensive results on the specific sex hormone, estradiol.

Frequently Asked Questions

  • Estrogen levels naturally decrease in women during perimenopause and menopause. If you are a woman who is nearing menopause, it is natural for your estrogen levels to fall. Conversely, if you are experiencing one or more of the common symptoms associated with low estrogen and you’re not at this stage in life, low levels could be a sign of a condition.

  • We understand that health testing can be a sensitive experience and you should expect a high degree of privacy. We utilize Quest Diagnostics collection sites that are discreet and nondescript. This means you will never be singled out for getting tested, and nobody in the lobby will know your reason for visiting. You will never be sent to a public clinic, health department, or doctor’s office.

  • All of the tests we offer are FDA approved and performed in CLIA certified labs to ensure the highest level of accuracy. If you’re testing for certain STDs, you’ll want to consider their latency periods as testing too quickly after exposure could produce an inaccurate result simply because the virus is too new to be detected. If you have questions, our care counselors are happy to walk you through the process, start to finish.
