Quick take
- Typical online self-pay price: about $47 to $101 for a single random growth hormone (GH/HGH) blood test when common mandatory order, draw, physician, requisition, or processing fees are included.
- Lowest listed effective price found: Ulta Lab Tests at about $46.90 when its $33.95 GH test price is combined with the standard $12.95 specimen collection fee noted in its FAQ. Pricing can vary by collection site. (ultalabtests.com)
- Important medical limitation: a single GH blood level is often not enough to diagnose growth hormone deficiency or excess because GH is secreted in pulses and changes with sleep, exercise, fasting, stress, and glucose levels. Labcorp’s test directory states that GH deficiency or excess is best evaluated with dynamic stimulation or suppression testing, and MedlinePlus explains that GH testing often involves multiple blood samples over a few hours. (labcorp.com)
- Best use case for a self-pay single GH test: when a clinician specifically asks for a random GH level, when you are monitoring a known condition under medical guidance, or when you are comparing out-of-pocket options for a lab order you already understand.
- Often-paired test: IGF-1, which is more stable across the day and reflects overall growth-hormone activity, is commonly used with GH testing for suspected acromegaly or other GH-axis concerns. (ondemand.labcorp.com)
Growth hormone blood test cost: self-pay comparison
If you are searching for growth hormone blood test blood test cost, the number that matters is not just the advertised test price. The useful number is the effective self-pay cost: the test price plus mandatory fees needed to place the order and have blood collected.
The table below compares publicly available U.S. online-order options for a single random GH/HGH blood test where current pricing could be identified. Prices can change, coupons may apply, and state availability can limit whether you can order or use a particular collection site. This comparison is sorted by effective cost to the patient where comparable, not by commission, brand preference, or endorsement.

Cost tip: if you are ordering multiple labs at the same visit, a provider that charges a single per-order requisition, draw, or processing fee may become more competitive than it looks for one test alone. Always compare the cart total for your exact test bundle, not only the individual GH line item.
How we compared growth hormone blood test costs
For this cost comparison, the key question was: What would a consumer likely pay out of pocket to order a single random growth hormone blood test online and complete the blood draw? We included the publicly visible GH/HGH test price, mandatory per-order physician or service fees, requisition charges, standard draw fees where stated, and processing fees where stated. We did not subtract coupons, promotional discounts, loyalty credits, or email sign-up offers because those can change quickly and may not apply to every customer.
We also separated a single random GH blood test from IGF-1 testing and from dynamic GH stimulation or suppression testing. This matters because the medically appropriate test may not be the cheapest test. Labcorp’s own GH test directory says random sampling should be done fasting after rest and that evaluation for GH deficiency or excess is best done using dynamic stimulation or suppression protocols; MedlinePlus similarly describes GH stimulation and suppression tests as multi-sample procedures. (labcorp.com)
Availability was also considered. Several online lab marketplaces cannot process direct-access medical lab testing in states such as New York, New Jersey, and Rhode Island, and some providers list additional state exclusions. For example, Jason Health says it serves 47 states except NY, NJ, and RI; Request A Test lists NY, NJ, and RI restrictions for Labcorp medical testing and NY, NJ, RI, and AZ restrictions for Quest medical testing; Discounted Labs lists the specific states it currently serves.

What does a growth hormone blood test measure?
A growth hormone blood test measures the concentration of human growth hormone, also called GH, HGH, somatotropin, or STH, in a blood sample. GH is produced by the pituitary gland and helps regulate growth, body composition, bone and tissue metabolism, and production of insulin-like growth factor 1 (IGF-1). MedlinePlus notes that GH tests may be used to help detect and monitor GH deficiency, gigantism, and acromegaly. (medlineplus.gov)
The challenge is that GH is not released at a steady rate. It is secreted in pulses, often with sleep-related peaks, and can be influenced by exercise, stress, fasting, illness, and glucose levels. That is why a low or high value on one random sample does not automatically diagnose deficiency or excess. Labcorp’s GH directory states that a single random GH measurement is limited for diagnosing GH disorders and that dynamic testing is preferred when deficiency or excess is the clinical question. (labcorp.com)
For suspected acromegaly, clinicians often begin with IGF-1 because IGF-1 is more stable and reflects GH activity over time. The Endocrine Society’s acromegaly guideline recommends measuring serum IGF-1 to help evaluate suspected acromegaly and confirming elevated or equivocal IGF-1 with lack of GH suppression after an oral glucose load. (academic.oup.com)
For suspected growth hormone deficiency, especially in children or adults with pituitary disease, a clinician may order a GH stimulation test rather than rely on a single baseline sample. MedlinePlus describes stimulation testing as giving a medicine that stimulates the pituitary gland, followed by additional blood samples over the next two hours. (medlineplus.gov)
Random GH vs IGF-1 vs stimulation or suppression testing
| Test type | What it can help with | Limitations | Typical self-pay availability |
|---|---|---|---|
| Random GH blood test | Measures GH at one point in time; may be used for monitoring or as part of a broader endocrine workup. | Single value is hard to interpret because GH is pulsatile and short-lived. | Commonly available through online lab marketplaces. |
| IGF-1 blood test | Reflects overall GH activity more steadily; often used in evaluation of acromegaly and other GH-axis concerns. | Can be affected by age, nutrition, liver disease, kidney disease, uncontrolled diabetes, and assay/reference-range differences. | Available through many online and direct lab services, including Labcorp OnDemand. (ondemand.labcorp.com) |
| GH suppression test | Used when GH excess is suspected; commonly involves glucose ingestion and timed GH samples. | Requires timing, fasting, glucose administration, and clinician interpretation. | Usually ordered and supervised through a clinician or endocrinology setting rather than simple online self-order. |
| GH stimulation test | Used when GH deficiency is suspected; medication stimulates GH release and timed samples are collected. | Medication choice, safety monitoring, and interpretation depend on age, BMI, pubertal status, and medical history. | Usually clinician-directed; not equivalent to a single self-pay GH blood draw. |
When is a self-pay GH blood test worth considering?
A self-pay GH test may be reasonable when you already have a clinician’s recommendation, need to compare cash prices because you are uninsured or have a high deductible, or want to avoid surprise billing for a lab you plan to discuss with a healthcare professional. It can also be useful when a clinician has ordered a repeat random GH level as part of monitoring a known pituitary or endocrine condition.
It is less useful as a stand-alone “wellness” screen. Symptoms that people associate with growth hormone imbalance—fatigue, changes in body composition, low energy, headaches, joint pain, slow growth in a child, or changes in facial/hands/feet size in adults—can have many causes. A random GH result by itself cannot sort those causes out. MedlinePlus describes GH disorders such as deficiency, gigantism, and acromegaly, but the testing process usually depends on the suspected condition and often includes additional hormones or dynamic testing. (medlineplus.gov)
If your concern is possible acromegaly, IGF-1 and an oral glucose tolerance GH suppression test may be more relevant than a single random GH. NIDDK states that a high IGF-1 level can suggest acromegaly and that an oral glucose tolerance test with GH measurements every half hour for two hours is used to confirm the diagnosis. (niddk.nih.gov)
How to prepare for a growth hormone blood test
Preparation instructions vary by provider and lab, so follow the instructions on your requisition. Common requirements include fasting and resting before collection. Labcorp states that random GH sampling should be performed on fasting patients who have rested for at least 30 minutes before collection. Request A Test’s GH page similarly says fasting is required and recommends resting because stress and exercise can raise GH levels. (labcorp.com)
- Fast as instructed. Some providers list 8 hours; others list 10–12 hours. Water is typically allowed unless your order says otherwise.
- Avoid strenuous exercise before the draw. Exercise can affect GH levels, and some provider pages specifically recommend rest before collection.
- Arrive early enough to sit quietly. If the lab is busy, tell the staff you were instructed to rest before a GH draw.
- Ask about biotin. Some lab pages recommend stopping biotin supplements for at least 72 hours before collection because biotin can interfere with some immunoassays. Request A Test and Labcorp OnDemand both provide biotin-related preparation language for hormone-related testing. (requestatest.com)
- Bring the requisition and ID requirements. Some providers send orders electronically; others require a printed form. Discounted Labs, for example, instructs customers to download and print the lab request. (discountedlabs.com)
How to interpret GH blood test results
Most GH results are reported in ng/mL or µg/L, with a reference interval supplied by the performing laboratory. Do not compare your number with another person’s result unless the same lab method, timing, preparation, age context, and clinical reason are considered. Labcorp lists a reference range for its growth hormone test, but its directory also emphasizes the limited diagnostic value of random GH sampling. (labcorp.com)
A low random GH does not necessarily mean GH deficiency. Because GH is pulsatile, a sample drawn between pulses can be low even in someone without deficiency. If deficiency is suspected—especially in a child with poor linear growth or an adult with pituitary disease—clinicians generally consider IGF-1, other pituitary hormones, imaging history, and stimulation testing.
A high random GH does not necessarily mean acromegaly or gigantism. GH can rise with stress, exercise, fasting, hypoglycemia, and other physiologic triggers. For suspected GH excess, clinicians often rely on IGF-1 and suppression testing rather than one random GH value. The Endocrine Society guideline recommends confirming elevated or equivocal IGF-1 with failure of GH to suppress after an oral glucose load. (academic.oup.com)
If your result is outside the reference interval, the practical next step is not to self-diagnose. Instead, document the timing, fasting status, exercise, sleep, medications, supplements, and reason for testing, then review the result with a clinician—ideally one comfortable with endocrine testing if GH imbalance is the concern.
Provider reputation and practical considerations
Public customer-review patterns can help you anticipate ordering experience, but they should not replace checking the actual checkout total and collection-site availability. Walk-In Lab has a large Trustpilot review base with a 4.8 score across about 6,000 reviews, and recent reviews commonly mention convenience, online ordering, and quick results. (trustpilot.com)
Ulta Lab Tests has a 4.5 Trustpilot score across 144 reviews and a BBB profile showing accreditation and an A+ rating, though its BBB customer-review count is small. Review themes include price, scheduling, and access to known labs. (trustpilot.com)
Jason Health has fewer public Trustpilot reviews—28 shown at the time checked—but a 4.4 score, with several recent reviewers highlighting low cost and easy ordering. Smaller review counts should be interpreted cautiously because a few reviews can move the score more than they would for a larger provider. (trustpilot.com)
HealthLabs’ Trustpilot page shows a 3.8 score across about 4,000 reviews and notes that the company has not recently invited reviews and has not replied to negative reviews on that platform. That does not mean the service is unsuitable, but it is a reminder to verify policies, lab locations, and final price before buying. (trustpilot.com)
Practical buying checklist
- Confirm the exact test: GH/HGH is not the same as IGF-1, IGFBP-3, or a multi-specimen stimulation/suppression panel.
- Compare cart totals: include draw fees, physician fees, requisition charges, processing fees, and any premium collection-site fee.
- Check your state: direct-access testing restrictions may block checkout or prevent collection at certain labs.
- Check lab network: choose based on nearby Quest, Labcorp, or other collection access, not just price.
- Follow preparation instructions: fasting, rest, and supplement holds can matter for GH testing.
- Plan interpretation: if you are concerned about acromegaly, GH deficiency, pituitary disease, or a child’s growth, arrange medical follow-up before ordering.
FAQs
How much does a growth hormone blood test cost without insurance?
For a single self-pay random GH/HGH blood test ordered online, the effective price commonly falls around $47 to $101 after mandatory fees found in public provider pages are included. The lowest effective price found in this review was about $46.90, but final checkout totals can change based on collection site, state, and provider fees.
Is the cheapest GH blood test always the best choice?
No. The best choice depends on the exact test, lab network, collection location, state availability, turnaround needs, and whether the test answers your medical question. A cheap random GH test may not be clinically useful if you actually need IGF-1 or a dynamic stimulation/suppression test.
Can I diagnose growth hormone deficiency from one GH blood test?
Usually not. GH is released in pulses, so a single low result can occur between pulses. Suspected GH deficiency is typically evaluated with clinical history, IGF-1 and related labs, and clinician-directed stimulation testing.
Can a random GH test diagnose acromegaly?
A random GH level alone is usually not enough. For suspected acromegaly, clinicians commonly use IGF-1 as an initial test and confirm with GH suppression testing after an oral glucose load when indicated.
Do I need to fast before a growth hormone blood test?
Often yes. Many GH test instructions call for fasting and resting before collection. Follow the instructions on your requisition; if instructions differ between the marketplace and the performing lab, ask the provider or lab for clarification before the draw.
What is the difference between GH and IGF-1 testing?
GH measures growth hormone at a specific moment. IGF-1 measures insulin-like growth factor 1, a hormone produced largely in response to GH that is more stable throughout the day. IGF-1 is often more useful for assessing overall GH activity, especially when GH excess is suspected.
Will insurance reimburse a self-pay online GH test?
Usually these marketplaces are designed for upfront self-pay and do not bill insurance. Some provide receipts with codes that you can submit, but reimbursement is not guaranteed. If insurance coverage matters, ask your insurer before ordering.
Why do some providers show a low test price but a higher total?
Many online lab marketplaces separate the lab test price from required order, physician, requisition, draw, or processing fees. The fair comparison is the checkout total for your order, not the headline test price.
