Also known as: HGH Test, Human Growth Hormone Test, Somatotropin Test, GH Blood Test, HGH Serum Test
The short answer
A single serum growth hormone (GH) level — the pituitary hormone behind growth, muscle and metabolism, measured from a standard blood draw. At TestWell it costs $49.99 plus a $6 lab processing fee, requires an 8–12 hour fast, and results post in 2–4 business days. Physician-authorized with no doctor's visit or insurance needed; draw at Quest or Labcorp.

Growth hormone (somatotropin) is made by the pituitary gland and released in short pulses, mostly during deep sleep and after exercise, with very low levels in between. That pulsatile pattern is the most important thing to know about this test: a single random GH level is a snapshot that can read near zero in a perfectly healthy adult and briefly high in another, which is why a one-off GH value is not used on its own to diagnose growth hormone deficiency or excess — clinicians rely on stimulation or suppression tests for that, and on IGF-1 as the steadier day-to-day marker of GH activity. Where a serum GH level earns its place is monitoring: people on a growth-hormone or secretagogue protocol tracking a trend alongside IGF-1, and pituitary evaluations where a provider has asked for a baseline GH. Draw it fasting, in the morning, after 30 minutes of rest — food, exercise and stress all push GH up — and read it next to IGF-1 rather than alone. Measured by immunoassay at Quest or Labcorp (BioReference in New York and New Jersey); the same Quest 521 / Labcorp 004275 tests other direct-access services charge $47–99 for.

1 biomarker tested
Your Growth Hormone (GH), Serum results will include values for each of the 1 biomarker tested, along with reference ranges. Results are reviewed by a licensed physician before being released to your secure portal.
If any values fall outside the normal range, your report will include guidance on what that may mean and recommended next steps. You'll receive an email notification when your results are ready, typically within 2–4 business days.
Typical reference range layout
Lab reports show where your value sits relative to established reference intervals—your physician interprets this in context for you. Already have results? Analyze them with your AI assistant against our physician-reviewed ranges.
Fast 8–12 hours (water is fine) and sit quietly for 30 minutes before the draw — food, exercise and stress all raise GH. A morning draw is preferred. Stop high-dose biotin 72 hours before (immunoassay). Keep taking prescribed medications unless your prescriber says otherwise.
