# Pregnenolone

> Pregnenolone is measured with a standard blood draw; no fasting is needed. A typical reference range is 22.0 – 237 ng/dL. At TestWell it's $49.99 all-in as Pregnenolone, results in 4–7 business days, drawn at Quest. An out-of-range result is a prompt to look closer, not a diagnosis.

Also known as: pregnenolone, pregnenolone, lc/ms, pregnenolone lc/ms.

The first steroid hormone made from cholesterol — the precursor to cortisol, DHEA, progesterone, testosterone and estrogen. Read with DHEA-S, cortisol and the sex hormones rather than alone.

Reference intervals differ slightly between labs; the range printed on your report is the one to interpret against. Ranges are usually set so 95% of healthy people fall inside them.
