Quick take
- Typical self-pay price: a basic cortisol blood test commonly falls around $37–$109 before optional discounts, depending on the ordering site, performing lab network, and whether a separate physician/order or draw fee is added.
- Lowest effective prices are not always the listed test price. For example, Ulta Lab Tests lists a Cortisol Total Test at $23.95, but its FAQ says a standard specimen draw fee of $12.95 is added at checkout, making the typical effective starting cost about $36.90. (ultalabtests.com)
- Quest Health’s cortisol test lists at $79 plus a $6 physician service fee, for an effective in-person cost of $85 before optional discounts or add-ons. (questhealth.com)
- Labcorp OnDemand lists its Cortisol Test at $89, with in-person collection at a Labcorp location and a recommended 7 a.m.–10 a.m. blood draw window. (ondemand.labcorp.com)
- Timing matters. Morning cortisol is normally highest early in the day, so a late draw can make a result hard to interpret. Quest’s cortisol test specifies 7 a.m.–9 a.m.; Labcorp OnDemand specifies 7 a.m.–10 a.m. (questhealth.com)
If you are comparing cortisol blood test cost without insurance, the key number is the effective total price: the test price plus any required physician service, requisition, or blood draw fee. A cortisol blood test is usually inexpensive compared with imaging or specialty visits, but prices vary widely because some websites sell the same or similar lab test through different ordering workflows.
A single cortisol blood result can be useful as a screening or context-setting test, especially when collected at the correct time of day. It is not, by itself, a complete diagnosis for Cushing syndrome, Addison disease, adrenal insufficiency, chronic stress, or pituitary disease. MedlinePlus notes that cortisol can be measured in blood, urine, or saliva, and that abnormal results do not automatically mean a person has a condition that needs treatment. (medlineplus.gov)
Self-pay cortisol blood test price comparison
The table below compares common national consumer ordering options available online. Prices can change, and some checkout totals vary by location, optional promotions, or the laboratory network selected. The comparison focuses on the cost a consumer can reasonably expect to pay for a single cortisol blood test order, not the provider’s advertised sale ranking or commission rate.

How we compare cortisol blood test prices
For this cost guide, the most important comparison standard is the total cost to the patient for a comparable self-pay order. That means we count mandatory physician oversight, service, requisition, and draw fees when the provider displays them. Optional promotional codes, newsletter discounts, in-home phlebotomy, membership bundles, or additional panels are not treated as the base price because they may not apply to every buyer.
We also distinguish between random cortisol, morning cortisol, afternoon/evening cortisol, and multi-sample cortisol. They are not always interchangeable. A $23.95 total cortisol test may be inexpensive, but if your clinician specifically asked for an 8 a.m. cortisol, a generic random cortisol order may not meet the purpose of testing. Ulta’s AM cortisol page, for example, specifies that the specimen must be drawn between 7 a.m. and 9 a.m. (ultalabtests.com)
Why cortisol blood test prices vary
Several factors explain the price spread:
- Ordering model: Some services use a consumer storefront with built-in physician oversight; others add a separate physician or service fee at checkout.
- Lab network: Some orders are collected at Quest, some at Labcorp, and some allow a choice. The same biomarker can have different retail prices depending on who sells the order.
- Timing specificity: A random cortisol, AM cortisol, PM cortisol, or AM/PM pair may use different test codes and prices.
- Collection fee: Some platforms include the draw fee in the displayed price; others add it separately. Ulta specifically states its standard draw fee is $12.95 unless a different collection site fee is shown. (ultalabtests.com)
- Optional services: Quest Health’s in-home sample collection can add $79 where available; this should not be confused with the base in-person test cost. (questhealth.com)
What a cortisol blood test measures
Cortisol is a steroid hormone made by the adrenal glands. It helps regulate blood pressure, glucose metabolism, immune and inflammatory responses, and the body’s response to physical and emotional stress. Cortisol production is controlled through the hypothalamic-pituitary-adrenal axis: the brain signals the pituitary gland, the pituitary releases ACTH, and ACTH stimulates the adrenal glands to produce cortisol.
A blood cortisol test measures the amount of cortisol in the bloodstream at the time the sample is collected. That timing is crucial because cortisol follows a daily rhythm. In people with a typical sleep-wake cycle, cortisol is usually highest in the early morning and declines later in the day. Quest explains that collecting its morning cortisol test outside the 7 a.m.–9 a.m. window can make results appear abnormal simply because cortisol naturally drops later. (questhealth.com)
When a blood cortisol test may be useful
A clinician may use a morning cortisol blood test as part of an evaluation for adrenal insufficiency, pituitary problems, or symptoms that could be related to too little cortisol. It may also be ordered with ACTH or followed by an ACTH stimulation test. ARUP Consult describes the short corticotropin, or ACTH stimulation, test as the gold-standard confirmatory test for primary adrenal insufficiency. (arupconsult.com)
For suspected Cushing syndrome, however, a routine morning blood cortisol is often not the best stand-alone screening test. The Endocrine Society guideline recommends initial testing with one high-accuracy test such as 24-hour urinary free cortisol, late-night salivary cortisol, or a dexamethasone suppression test. (pmc.ncbi.nlm.nih.gov)
This difference matters when you are shopping by price. If you buy the cheapest single cortisol blood test but your clinical question requires late-night salivary cortisol, urinary free cortisol, or suppression testing, you may spend less today but still need additional testing later.
How to prepare for a cortisol blood test
Follow the preparation instructions on your lab order. Common preparation points include:
- Schedule the correct time window. Morning cortisol is commonly collected around 7 a.m.–9 a.m. or 7 a.m.–10 a.m., depending on the order. (ultalabtests.com)
- Ask before stopping medicines. Steroid medications, including hydrocortisone, prednisone, prednisolone, inhaled steroids, topical steroids used over large areas, injections, and some hormone therapies can affect interpretation. Do not stop prescribed medication unless your clinician tells you to.
- Pause high-dose biotin if instructed. Several consumer lab pages recommend stopping biotin for at least 72 hours before collection because it can interfere with some immunoassay-based lab tests. (ondemand.labcorp.com)
- Document pregnancy, estrogen therapy, oral contraceptives, and shift work. These can change cortisol patterns or binding proteins and may affect how a clinician interprets the result.
- Keep the day ordinary if possible. Acute illness, intense exercise, poor sleep, and major stress can affect cortisol. A result from an unusually stressful day may not represent your usual baseline.
How to interpret the result
Use the reference interval printed on your own lab report, because ranges vary by lab, assay, and collection time. A morning cortisol value that is normal for an 8 a.m. sample may not be interpreted the same way if the blood was drawn at 2 p.m.
Low morning cortisol can raise concern for adrenal insufficiency, especially when symptoms fit and ACTH is abnormal. The Endocrine Society’s hypopituitarism guidance says an 8–9 a.m. serum cortisol below 3 micrograms per deciliter is indicative of adrenal insufficiency, while a value above 15 micrograms per deciliter likely excludes it; intermediate values generally require corticotropin stimulation testing. (endocrine.org)
High cortisol can occur for many reasons, including physiologic stress, pregnancy, estrogen therapy, depression, alcohol use, obesity, medication effects, or true cortisol excess. A high value on a single blood draw is not enough to diagnose Cushing syndrome. If Cushing syndrome is a concern, clinicians usually choose a specific screening strategy and may repeat testing because cortisol secretion can vary.
Blood, saliva, and urine cortisol: cost versus clinical fit
| Test type | Best fit | Cost considerations | Limitations |
|---|---|---|---|
| Morning blood cortisol | Initial look at possible low cortisol or adrenal/pituitary function | Often one of the lowest-cost options | Very timing-sensitive; may need ACTH or stimulation testing |
| PM or late-day blood cortisol | Evaluating whether cortisol declines later in the day | Similar to single blood cortisol pricing | Less commonly used as a stand-alone consumer screen; timing still matters |
| Late-night salivary cortisol | Common screening option for suspected Cushing syndrome | May cost more than a single blood draw, especially with multiple samples | Collection technique and contamination matter; cutoffs are lab-specific |
| 24-hour urinary free cortisol | Assessing cortisol production over a full day | Usually more than a single blood test but may be clinically more relevant for cortisol excess | Requires complete 24-hour urine collection; often repeated |
| Dexamethasone suppression test | Screening for cortisol excess under clinician direction | May involve medication and timed blood draw | Medication interactions and estrogen therapy can affect results |
Provider shopping notes
Ulta Lab Tests is often the lowest-cost path for a single cortisol order after adding its standard draw fee. Public customer reviews are generally favorable on Trustpilot, while BBB review volume is smaller and more mixed; consumer reviews should be treated as experience signals, not proof of medical quality. (trustpilot.com)
Quest Health is straightforward if you want to order directly through Quest’s consumer site and use a Quest location. Its effective cost is higher than some third-party ordering sites, but the workflow includes Quest’s own registration and result system, independent healthcare provider oversight, and the option to discuss results at no extra cost according to Quest’s product page. (questhealth.com)
Labcorp OnDemand may be attractive if you prefer Labcorp locations or already use a Labcorp Patient account. The cortisol page lists $89 and says the test must be taken by the purchaser, is for ages 18–100, and should be collected between 7 a.m. and 10 a.m. (ondemand.labcorp.com)
Walk-In Lab and Request A Test are middle-price options with explicit per-order fees. They can be useful when they offer the specific cortisol timing or lab network you need. Always check whether the order is AM, PM, random, serum, saliva, or urine before buying.
Insurance, HSA/FSA, and doctor-ordered testing
Most consumer-initiated lab sites are designed for direct payment and do not bill insurance. Quest Health states that tests purchased on questhealth.com are intended for direct payment and cannot be submitted for insurance reimbursement. (questhealth.com)Labcorp similarly states that Labcorp OnDemand does not bill insurance and that consumers pay up front by credit card or HSA/FSA dollars. (labcorp.com)
If your clinician orders cortisol testing for symptoms or a known medical condition, insurance may cover some or all of the cost depending on your plan, diagnosis codes, deductible, and network rules. The tradeoff is that the final out-of-pocket amount may be less transparent until the claim processes. If you are self-pay, ask whether the physician’s office or local hospital lab has a cash price; sometimes local clinic cash prices are lower than national online retail prices, but they vary heavily.
Practical next steps before you buy
- Clarify the clinical question. Are you checking possible low cortisol, high cortisol, medication suppression, circadian rhythm, or general wellness?
- Match the exact test type. If you need AM cortisol, buy an AM cortisol order, not a random cortisol order unless your clinician says it is acceptable.
- Compare total cost. Add required draw, physician, and service fees before choosing.
- Check state availability. Quest Health says its lab tests are not currently available in Arizona, Hawaii, and Puerto Rico; Ulta says direct-access testing is not available for residents of New York, New Jersey, and Rhode Island. (questhealth.com)
- Schedule the right time. For morning cortisol, choose an early appointment and arrive with enough time to avoid missing the collection window.
- Plan follow-up. Share abnormal or confusing results with a qualified clinician, especially if you have symptoms, take steroids, are pregnant, or have known pituitary or adrenal disease.
FAQs
How much does a cortisol blood test cost without insurance?
A self-pay cortisol blood test commonly costs about $37–$109 through major online ordering options after mandatory fees. The low end usually comes from discounted third-party ordering sites after adding a draw fee; direct Quest Health and Labcorp OnDemand options are commonly around $85–$89 for in-person collection based on current listed prices. (ultalabtests.com)
What is the cheapest cortisol blood test option?
Among the options reviewed here, Ulta Lab Tests shows one of the lowest effective prices: $23.95 for Cortisol Total plus a standard $12.95 draw fee, or about $36.90 before any unusual location-specific fee. If you specifically need morning cortisol, Ulta’s AM cortisol test lists at $28.95 plus the draw fee, or about $41.90. (ultalabtests.com)
Is Quest or Labcorp cheaper for cortisol testing?
Quest Health’s cortisol test lists at $79 plus a $6 physician service fee, or about $85. Labcorp OnDemand’s cortisol test lists at $89. The difference is small, so convenience, appointment availability, state availability, and result access may matter more than the $4 base-price difference. (questhealth.com)
What time should I take a cortisol blood test?
For a morning cortisol test, follow the order’s specified window. Quest Health recommends 7 a.m.–9 a.m.; Labcorp OnDemand recommends 7 a.m.–10 a.m. Timing matters because cortisol is normally highest in the morning and lower later in the day. (questhealth.com)
Can a single cortisol blood test diagnose Cushing syndrome?
Usually not. A single blood cortisol result can provide useful context, but the Endocrine Society recommends specific high-accuracy initial tests for suspected Cushing syndrome, such as urinary free cortisol, late-night salivary cortisol, or dexamethasone suppression testing. (pmc.ncbi.nlm.nih.gov)
Can a single morning cortisol test diagnose adrenal insufficiency?
Sometimes it can strongly suggest or argue against adrenal insufficiency, but many borderline results require follow-up. Endocrine Society guidance for central adrenal insufficiency says an 8–9 a.m. cortisol below 3 micrograms per deciliter is indicative, above 15 likely excludes the diagnosis, and values between those thresholds generally need corticotropin stimulation testing. (endocrine.org)
