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 made mainly by the adrenal glands. Pregnenolone is converted into other steroid hormones such as progesterone, testosterone, and estrogen, but this test reports pregnenolone levels only. The result can help your healthcare provider evaluate this part of the steroid hormone pathway, alongside your symptoms and medical history. This test does not diagnose any condition on its own.
2. Who would benefit from this test?
People experiencing fatigue, low libido, memory concerns, or mood changes such as depression or anxiety may benefit from this test. It may also be useful for those with menstrual irregularities, fertility concerns, autoimmune conditions, chronic inflammation, or low testosterone symptoms. Your healthcare provider can help determine whether this test fits your specific situation.
3. When should I order this test?
You might consider this test if you are experiencing fatigue, insomnia, low libido, memory or concentration difficulties, joint pain, weight changes, hair loss, or skin dryness. It can also be used to evaluate adrenal gland function as part of a broader discussion with your healthcare provider. This test is one piece of information and does not replace a full medical evaluation.
4. How does this test differ from other hormone tests?
This test measures pregnenolone specifically, which is a precursor hormone rather than an active end-stage hormone like progesterone, testosterone, or estrogen. Because pregnenolone is upstream in the steroid hormone pathway, this result does not provide the same information as tests measuring those downstream hormones directly. This test uses LC/MS-MS methodology to measure pregnenolone in blood.
5. Do I need to fast before this test?
No special preparation is required for this test.
6. How quickly will I get results?
Results are typically available in 7-10 days. Results may take longer based on weather, holidays, or other lab delays.
7. How do I interpret the results?
Pregnenolone results are best interpreted alongside your symptoms, medical history, and other relevant factors, since this test measures a precursor hormone rather than an end-stage hormone. An abnormal result does not automatically confirm a hormonal condition, and a normal result does not automatically rule one out. Because pregnenolone feeds into other hormone pathways, your provider may consider it together with other hormone measurements when relevant.
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.
8. What should I do if my results are abnormal?
If your results fall outside the expected range, review them with a qualified healthcare provider. They can help determine what the result means in the context of your symptoms and health history, and whether additional evaluation or testing may be appropriate. This test result alone does not provide a complete clinical conclusion.
9. How often should I get tested?
Testing frequency should be determined as directed by your healthcare provider, based on your individual health needs and the reason this test was ordered. There is no standard repeat testing schedule associated with this test.
Pre test preparation
No special preparation is required.
