Pregnenolone Sulfate
Pregnenolone sulfate is the sulfated form of pregnenolone, an important precursor to virtually all steroid hormones. This substance is more soluble and more stable in the blood than pregnenolone and serves as a storage and transport form. In addition, pregnenolone sulfate acts as a neurosteroid and is involved in the functioning of the brain and nervous system.
A pregnenolone sulfate test may be used as part of a comprehensive hormonal evaluation or when assessing steroid hormone levels. The results are always interpreted in conjunction with the patient’s symptoms and any other hormone levels, such as DHEA, cortisol, progesterone, and sex hormones.
When is a pregnenolone sulfate test recommended?
This test may be considered in the following situations, among others:
- Fatigue or prolonged exhaustion.
- Hormonal symptoms where a more comprehensive hormone profile is recommended.
- Test for steroid hormone production.
- Symptoms in which the function of neurosteroids may play a role, such as concentration or memory problems (always in conjunction with a medical evaluation).
What does this test measure?
This blood test measures the concentration of pregnenolone sulfate in the blood. The results provide insight into the amount of this stable storage form of pregnenolone and, together with other laboratory results, can contribute to the assessment of hormonal balance.
Important to know
- Pregnenolone sulfate is not the same as pregnenolone. It is the more stable, sulfated form of the hormone.
- The results should always be interpreted in conjunction with the patient’s medical history, symptoms, and any additional hormone tests.
- An abnormal result does not automatically lead to a diagnosis and often requires further testing or consultation with a doctor.
The test has changed since July 3, 2026: Pregnenone sulfate is now tested instead of pregnenolone.
