Hydroxyprogesterone Blood Test

$58.00 AUD

Investigating adrenal function, screening for CAH, or evaluating hormonal symptoms that might stem from enzyme deficiencies in cortisol production?

Measures 17-hydroxyprogesterone, a precursor hormone in cortisol production. Elevated levels indicate enzyme deficiencies in the adrenal pathway, most commonly congenital adrenal hyperplasia (CAH).

Overview

The 17-Hydroxyprogesterone test measures a hormone intermediate in your adrenal glands' production of cortisol. When enzymes needed to complete cortisol synthesis are deficient or absent, 17-OHP accumulates in the bloodstream at detectable levels.

This accumulation pattern serves as the primary screening and diagnostic marker for congenital adrenal hyperplasia (CAH)—a group of inherited enzyme deficiencies. Classic CAH presents in infancy, but milder non-classic forms may go undiagnosed until adulthood, causing symptoms like irregular periods, excess hair growth, acne, or fertility problems.

The test suits Australians investigating possible CAH, those with symptoms suggesting androgen excess, and anyone with family history of adrenal enzyme deficiencies who wants screening.

Symptoms

Essential for people being screened for CAH, those with symptoms of androgen excess, women with fertility issues, or anyone with family history of adrenal enzyme deficiencies.

Questions

  • 17-OHP is a hormone intermediate in cortisol production. When enzymes converting it to cortisol are deficient, 17-OHP accumulates—the basis for CAH diagnosis.
  • CAH is a group of inherited enzyme deficiencies affecting cortisol production. The most common form (21-hydroxylase deficiency) causes 17-OHP elevation and can range from mild to severe.
  • Severe CAH can cause life-threatening salt-wasting crises in newborns. Early detection through 17-OHP screening allows treatment before complications develop.
  • Yes. Non-classic (mild) CAH may not be diagnosed until adulthood when symptoms like irregular periods, excess hair growth, or infertility prompt investigation.
  • Treatment replaces deficient hormones (cortisol, sometimes aldosterone) and may include medications to control androgen excess. Lifelong management is usually required.
  • Testing is appropriate for suspected CAH, investigation of androgen excess, fertility evaluation, or family history of adrenal enzyme deficiencies.

How to prepare

Timing may be important for menstruating women (typically tested in follicular phase). Inform healthcare provider of all medications, particularly hormones, that might affect results. Stress can affect levels.

After the test

Address elevated 17-OHP through comprehensive endocrine evaluation, genetic counseling if CAH is suspected, appropriate hormone replacement therapy, and regular monitoring. Work with endocrinologists for specialized care.

Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.

Understanding results

Results show 17-OHP levels compared to normal ranges. Elevated levels may indicate CAH or other adrenal disorders requiring further evaluation, genetic counseling, and appropriate hormone replacement therapy.

Simple health checks in my control

I didn't know that private blood tests were an option. Tried this platform as the packages suited what I wanted for a good price. Easy to follow instructions, and super quick results. Platform provides more information than my gp's ever have on the tests and what the results meant. Would like more clinics to be able to test at (specifically Capital Pathology) but there is a decent network. Will continue to use.

"I'm a little biased as I work here! However, I love that The Bloody Good Test tracks my health over time. After turning 40, I wanted to make sure I wasn't going to drop dead from something basic I should have known about earlier. Measuring all my core biomarkers each year gives me peace of mind my health is on the right track"
