About Pregnenolone

What is pregnenolone?

Pregnenolone is a steroid hormone produced by the adrenal gland from cholesterol. Pregnenolone is a precursor to other hormones including testosterone, oestrogen and cortisol. It also has an important role in brain function and is used as a medicine for schizophrenia.

Maintaining the correct hormone balance involves a complex interconnected network of hormone levels and is essential for keeping the body healthy.

Both excessive production and a deficiency in the production of steroid hormones may indicate an underlying illness. Disorders related to changes in pregnenolone levels include congenital adrenal hyperplasia, a rare disorder characterised by low levels of cortisol and high levels of male hormones.  

Why take this test?
