How much does a cortisol blood test cost? If you are paying cash for a direct-to-consumer morning cortisol blood test, expect a practical range of about $36 to $109 among commonly available online ordering options reviewed for this article. The lowest current effective price we found was Ulta Lab Tests’ Cortisol AM Test at a promotional test price of $23.16 plus its standard $12.95 specimen collection fee, while Quest Health listed its Cortisol Stress Hormone Test at $79 plus a $6 physician service fee, Labcorp OnDemand listed its Cortisol Test at $89, and HealthLabs listed its Cortisol Test at $109. Own Your Labs listed a lower-priced cortisol blood test at $19.80 with the standard participating-site blood draw included, but its public listing did not label that item specifically as a 7–9 a.m. “AM cortisol” test, so verify timing before using it for a clinician-requested morning cortisol result.
Quick Take
- Most direct-pay morning cortisol blood tests cost under $110, but the all-in amount depends on physician/order fees, collection fees, and whether a promotion is actually applied at checkout.
- Morning serum cortisol, saliva cortisol, and 24-hour urine cortisol are different tests. They should not be compared as if they measure the same thing.
- Timing matters. Morning cortisol is typically collected around 7–9 a.m. because cortisol normally peaks early in the day.
- A single cortisol blood result rarely answers the whole question. Clinicians often interpret it with symptoms, medication history, ACTH, stimulation testing, dexamethasone suppression testing, saliva testing, or urine testing depending on the concern.
- Do not stop steroid medicines or hormone therapy on your own for testing. Ask the ordering clinician or lab how to handle medications that can affect cortisol results.

Why cortisol test prices vary
Cortisol blood test cost is not just the laboratory assay price. For direct-access testing, the amount you actually pay may include a clinician authorization or physician service fee, a blood draw fee, a per-order requisition or processing fee, and sometimes shipping if a home kit is involved. Quest Health separates a $6 physician service fee from the $79 test price, while Labcorp OnDemand says physician services are included in its OnDemand testing cost. Ulta adds a standard draw fee to the cart for specimen collection, and HealthLabs states there are no additional charges after ordering for visiting the test center or getting results. Insurance changes the math. If your clinician orders a cortisol test through insurance, your out-of-pocket cost may be $0, a copay, coinsurance, or the full contracted amount until your deductible is met. The online cash prices above are useful when you are intentionally self-paying, comparing prices before using insurance, or ordering through a direct-access pathway. They are not the same as a hospital chargemaster price, an insurer-negotiated rate, or a bill for an endocrine workup that includes multiple timed tests.
What a morning cortisol blood test measures
A morning cortisol blood test measures cortisol in serum or plasma from a venous blood draw, usually when cortisol should be near its daily high point. Quest Health describes its test as a single blood draw collected in the 7–9 a.m. peak window, and Ulta’s Cortisol AM page gives the same 7–9 a.m. collection instruction. Labcorp’s test directory notes that blood drawn at 8 a.m. and 4 p.m. may be used to evaluate baseline daily variation and that a morning specimen is often ordered with ACTH. Most routine serum cortisol assays measure total cortisol, which includes cortisol bound to proteins as well as free cortisol. That matters because binding proteins can change with pregnancy, estrogen therapy, and some oral contraceptives. Labcorp’s test directory specifically notes that pregnancy, contraceptives, and estrogen therapy can raise cortisol concentrations, and it also notes possible falsely elevated cortisol with prednisolone, methylprednisolone, or prednisone exposure in that assay context.
Lab Tech Insight
For cortisol, the clock is part of the specimen. A tube drawn at 8:05 a.m. and a tube drawn at 3:30 p.m. are not interchangeable, even if both are labeled “cortisol.” When you receive results, check the collection time, specimen type, and reference interval before deciding whether a value is truly high or low for that draw.
Blood, saliva, and urine cortisol: do not conflate the tests
Morning serum cortisol is often used as an accessible first look at cortisol status, especially when a clinician is considering adrenal insufficiency or wants a morning value alongside ACTH. Saliva and urine cortisol tests answer different questions.
Salivary cortisol measures cortisol in saliva, which better reflects free cortisol rather than total protein-bound cortisol. Late-night salivary cortisol is used in evaluation for loss of the normal nighttime cortisol low point, a key feature considered in Cushing syndrome workups. The Endocrine Society Cushing guideline discusses late-night salivary cortisol, 24-hour urinary free cortisol, and dexamethasone suppression testing as recommended first-line screening approaches for suspected Cushing syndrome rather than relying on random serum cortisol alone.Twenty-four-hour urinary free cortisol measures free cortisol excreted in urine over a full day. This can be useful when the question is whether overall daily cortisol production is excessive, but it depends heavily on a complete and correctly timed urine collection. The Endocrine Society guideline emphasizes the importance of complete 24-hour urine collection and appropriate urine creatinine/volume checks when using urinary free cortisol.Dexamethasone suppression testing is another separate pathway. It is not simply a cortisol blood test purchased at a random time. It evaluates whether cortisol suppresses after dexamethasone exposure under a specific protocol. Labcorp’s test directory lists dexamethasone suppression screening as related information to cortisol testing, and Cushing guidelines include dexamethasone suppression among major screening options.
When a morning cortisol blood test is commonly paired with other labs
A single morning cortisol result can be informative, but it is rarely definitive by itself. For possible adrenal insufficiency, clinicians commonly interpret morning cortisol with ACTH because ACTH helps distinguish whether the signaling problem may be at the adrenal gland level or higher in the pituitary/hypothalamic axis. The Endocrine Society primary adrenal insufficiency guideline says that if a corticotropin stimulation test is not feasible, a morning cortisol below 5 µg/dL together with ACTH can be used as a preliminary test suggestive of adrenal insufficiency until confirmatory stimulation testing is available.For central adrenal insufficiency, the Endocrine Society guideline for hypopituitarism suggests measuring serum cortisol at 8–9 a.m. as a first-line test and performing corticotropin stimulation testing when morning cortisol values are in an intermediate range.For suspected cortisol excess, morning serum cortisol alone is often less helpful. Cortisol normally rises in the morning, and stress, illness, poor sleep, medications, pregnancy, and estrogen effects can all shift results. Clinicians more commonly use late-night salivary cortisol, 24-hour urinary free cortisol, and/or dexamethasone suppression testing when the clinical question is Cushing syndrome or another hypercortisolism pattern.
Preparation factors that can affect price, convenience, and accuracy
Schedule early enough. Many patient service centers fill early appointments quickly. If your requisition specifies 7–9 a.m., choose a location and appointment time that realistically lets the sample be drawn in that window. Quest and Ulta both emphasize morning-only collection for their morning cortisol options.Ask about medications before the draw. Glucocorticoids such as hydrocortisone, prednisone, prednisolone, methylprednisolone, dexamethasone, steroid injections, inhaled steroids, topical steroids, and some hormone therapies can affect cortisol interpretation. Do not stop prescribed medication just to “get a cleaner result” unless the ordering clinician tells you exactly how to handle it.
Check biotin instructions. Some immunoassays can be affected by high-dose biotin supplements. Labcorp’s cortisol directory cautions about high-dose biotin and recommends asking about biotin supplementation; Own Your Labs’ public cortisol listing also instructs users to avoid biotin supplementation for 72 hours before testing.Know whether fasting is required. Cortisol itself is often more timing-sensitive than fasting-sensitive, but a panel that includes glucose, insulin, lipids, or other metabolic markers may require fasting. Follow the requisition rather than generic online advice.
How to interpret low, normal, or high morning cortisol results
Reference intervals vary by laboratory, method, age, and collection time. Labcorp’s directory lists an AM reference range of 6.2–19.4 µg/dL and a PM reference range of 2.3–11.9 µg/dL for its cortisol assay, while an ARUP sample report lists a 6 a.m.–10 a.m. interval of 6.0–18.4 µg/dL and a 4 p.m.–8 p.m. interval of 2.7–10.5 µg/dL. These examples show why the reference interval attached to your own result matters more than a number copied from another lab.Low morning cortisol may lead a clinician to consider adrenal insufficiency, pituitary/hypothalamic signaling problems, medication suppression from glucocorticoids, or other clinical contexts. It is typically interpreted with symptoms, sodium and potassium patterns, blood pressure, ACTH, renin/aldosterone when appropriate, and sometimes ACTH stimulation testing.
High morning cortisol is not automatically Cushing syndrome. Acute stress, pain, illness, poor sleep, recent exercise, depression, alcohol use, pregnancy, estrogen-containing medication, and assay cross-reactivity can all affect cortisol results. A clinician concerned about true cortisol excess usually chooses tests designed for that question, such as late-night salivary cortisol, 24-hour urinary free cortisol, or dexamethasone suppression testing.Normal morning cortisol can be reassuring in some contexts, but it does not always rule out every endocrine condition. If symptoms are significant, if the result conflicts with the clinical picture, or if the value falls in an intermediate zone, clinicians may repeat the test under stricter timing or move to paired or dynamic testing.
Choosing among testing options
If you are comparing costs because a clinician asked for an AM cortisol, choose a product that clearly supports a morning serum cortisol collection and confirm the appointment window. If you are exploring cortisol because of sleep timing, circadian rhythm, or possible cortisol excess, a saliva or urine option may be the test your clinician actually wants, but it should be selected by clinical question rather than price alone.
Quest Health currently offers both a single morning blood cortisol test and broader cortisol/DHEA-S options, including a full-day assessment that uses salivary cortisol at four points. Ulta also lists cortisol saliva options, including a four-sample saliva test, but these are not the same as a single morning blood draw and should not be compared as if the lower or higher price means a better test.
Frequently asked questions
How much does a cortisol blood test cost without insurance?
For direct-to-consumer morning cortisol blood testing, commonly advertised cash prices are roughly $20 to $110 before any provider-specific collection or order fees. In the providers reviewed, effective consumer prices ranged from about $36 with a current Ulta promotion and standard draw fee to $109 at HealthLabs, while Quest Health listed $79 plus a $6 physician service fee and Labcorp OnDemand listed $89.
Is a morning cortisol blood test the same as a saliva cortisol test?
No. A morning serum cortisol test is a venous blood test that measures total cortisol at one point in the morning. Saliva cortisol measures free cortisol in saliva and is often collected at specific times, especially late at night or across multiple daily samples, depending on the clinical question.
Is a 24-hour urine cortisol test better than a blood test?
It is not simply better; it answers a different question. A 24-hour urinary free cortisol test estimates cortisol production over a full day and is commonly used in evaluation for cortisol excess. A morning blood cortisol test is more often used as a starting point for possible cortisol deficiency or as part of a broader endocrine evaluation.
Do I need to fast for a morning cortisol test?
Many cortisol blood tests do not require fasting, but the exact instructions come from the ordering provider or lab. Timing is usually more important than fasting: morning cortisol is commonly collected between about 7 a.m. and 9 a.m. Ask about steroid medicines, estrogen-containing medicines, and high-dose biotin before testing because they may affect results or assay interpretation.
Can a single cortisol blood test diagnose Cushing syndrome or Addison disease?
Usually no. A single cortisol result can be useful context, but endocrine conditions are diagnosed with the medical history, examination, and the right confirmatory or paired tests. Clinicians may pair morning cortisol with ACTH, use an ACTH stimulation test for adrenal insufficiency, or use late-night salivary cortisol, 24-hour urinary free cortisol, or dexamethasone suppression testing when evaluating cortisol excess.
Practical next steps
- Match the test to the clinical question. Do not substitute a saliva or urine cortisol test for a requested morning blood cortisol result unless the ordering clinician agrees.
- Compare the total price, not just the test price. Include physician/order fees, blood draw fees, shipping, and any required membership or processing charge.
- Confirm availability in your state and collection network. Direct-access lab rules and provider restrictions vary.
- Schedule the draw for the correct time. For AM cortisol, aim for the stated 7–9 a.m. or 8–9 a.m. window on your order.
- Bring results back to a qualified clinician if the value is low, high, unexpected, or connected to symptoms such as unexplained weight change, blood pressure changes, faintness, severe fatigue, muscle weakness, new diabetes, easy bruising, or steroid medication use.
