What This Test Measures
This test measures pregnenolone, a steroid hormone precursor, in your blood using LC/MS-MS methodology. Pregnenolone is produced primarily by the adrenal glands, with smaller amounts made in the liver, brain, skin, and gonads. As a precursor hormone, pregnenolone is converted into other steroid hormones, including progesterone, testosterone, and estrogen, but this test reports only the pregnenolone level itself.
Because pregnenolone sits upstream in the steroid hormone pathway, this result reflects precursor availability rather than the levels of the hormones it may later become. It does not measure progesterone, testosterone, estrogen, or any other downstream hormone, and it does not represent a complete picture of adrenal or endocrine function on its own.
Benefits
- Measures circulating pregnenolone using precise LC/MS-MS methodology.
- Helps evaluate a key precursor in the steroid hormone pathway.
- Supports discussions about adrenal gland function with your provider.
- Can be used alongside other evaluations of hormone-related symptoms.
- Offers a straightforward blood test with no special preparation.

- Those experiencing symptoms of depression or anxiety.
- Women with menstrual irregularities or fertility-related concerns.
- Individuals managing autoimmune conditions or chronic inflammation.
- Men experiencing low testosterone symptoms or erectile dysfunction.

FAQ
1. What is the purpose of this hormone test?
This test measures pregnenolone, a precursor hormone produced mainly by the adrenal glands. Pregnenolone is converted into other steroid hormones, including progesterone, testosterone, and estrogen, but this test reports pregnenolone only. The result may help a healthcare provider evaluate this part of the steroid hormone pathway alongside your symptoms and medical history. It does not diagnose any condition on its own.
2. Who may benefit from this test, and when should it be ordered?
This test may be considered by people experiencing fatigue, insomnia, low libido, memory or concentration difficulties, depression, anxiety, joint pain, weight changes, hair loss, or skin dryness. It may also be useful for those with menstrual irregularities, fertility concerns, autoimmune conditions, chronic inflammation, or symptoms of low testosterone. A healthcare provider may use the test to evaluate adrenal gland function as part of a broader medical assessment.
3. How does this test differ from other hormone tests?
This test uses LC/MS-MS methodology to measure pregnenolone in the blood. Pregnenolone is an upstream precursor rather than an active end-stage hormone such as progesterone, testosterone, or estrogen. Therefore, its result does not provide the same information as tests that measure those downstream hormones directly.
4. Do I need to prepare for this test?
No special preparation is required.
5. How quickly will I receive my results?
Results are typically available within 7–10 days. They may take longer because of weather, holidays, or other laboratory delays.
6. How do I interpret the results?
Pregnenolone results should be interpreted alongside your symptoms, medical history, and other relevant factors. Because pregnenolone feeds into other hormone pathways, a healthcare provider may consider the result together with other hormone measurements when relevant. An abnormal result does not automatically confirm a hormonal condition, and a normal result does not automatically rule one out.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
7. What should I do if my results are abnormal?
Review results that fall outside the expected range with a qualified healthcare provider. They can explain what the result may mean in the context of your symptoms and health history and determine whether additional evaluation or testing is appropriate.
8. How often should I get tested?
There is no standard repeat-testing schedule for this test. Your healthcare provider should determine the appropriate frequency based on your individual health needs and reason for testing.
