What this test is

Pregnenolone is a steroid hormone produced mainly in the adrenal glands, and it serves as a building block for other hormones. This test measures how much pregnenolone is present in the blood at the time of collection. It is typically ordered when a clinician wants to assess part of the hormone pathway.

What it measures

  • Pregnenolone — reflects the amount of this hormone circulating in the blood
  • Pregnenolone level relative to reference range — shows whether the value falls within the lab's expected range
  • Hormone pathway context — may be considered with other hormone results to assess overall production

What the test involves

The test requires a standard blood draw, usually from a vein in the arm. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order this test to help evaluate symptoms that could be related to hormone imbalances or adrenal function. It is often used alongside other hormone tests to get a fuller picture.

Preparation

Preparation instructions can vary, so follow the specific directions provided by the collection lab. This may include timing the test to a certain part of your cycle or avoiding certain medications, but only your lab or clinician can confirm what applies to you.

How results are reported

Results are reported as a numeric value for the amount of pregnenolone in the blood. Reference ranges differ from one laboratory to another, so your result should always be interpreted using the range provided by the testing lab.

Before you go

  • Whether any medications or supplements should be avoided before the test
  • The best time of day or cycle to collect the sample
  • How long results typically take and how they will be shared
