How Much Does a Cortisol Test Cost? Blood, Saliva and Urine Cortisol Prices by Setting, With and Without Insurance — and Which Test You Actually Need

There is no single "cortisol test," which is why prices range from $27 to $600. The morning serum cortisol is a plain blood draw — $26.99 through TestWell, $79 on Quest's own site, $150–$400 by the time a doctor's visit is attached — and it is the reasonable first look when the worry is too little cortisol (fatigue with low blood pressure, salt craving, weight loss, darkening skin). The tests for too much cortisol — Cushing's syndrome — are different: a late-night salivary cortisol, a 24-hour urine free cortisol or a dexamethasone suppression test, each $100–$300 and ordered by a clinician because a single morning blood value cannot screen for it. An ACTH stimulation test, used when a morning level is ambiguous, is a clinic procedure at $300–$600. Insurance pays for all of these when symptoms justify them and for none of them as a wellness check. The expensive mistake in this family is not overpaying for the blood test; it is buying the blood test to answer a question it cannot answer, then paying again for the right one.

Self-pay prices. Where a route requires a visit, the visit is included because you cannot get the test without it.

Rows one and two are not alternatives to the blood test — they answer different questions. If your question is "is my cortisol too high," the cheap blood test is not the cheap option, because it does not answer it.

Cortisol follows a daily rhythm: highest in the first hour after waking, falling through the day to its lowest point around midnight. That rhythm is why every cortisol test specifies a time, and why a result without a time is nearly meaningless. A morning serum cortisol drawn between 7 and 9 AM is the Endocrine Society's first-line test when adrenal insufficiency is suspected: a clearly low value supports the diagnosis, a robustly normal value makes it unlikely, and values in between are sorted out with an ACTH stimulation test. It is not a screening test for Cushing's syndrome, because people with too much cortisol often have a normal morning level; what they lose is the night-time dip, which is why the Cushing's screens measure cortisol late at night (saliva), across a whole day (24-hour urine) or after a suppression dose (dexamethasone).

Two things distort a blood cortisol and are worth knowing before you pay. Oral estrogens (the pill, some hormone therapy) raise the protein that carries cortisol and so raise the total level without changing the active fraction. Prednisone and other glucocorticoids suppress your own production and some cross-react with the assay. And a word about "adrenal fatigue": the Endocrine Society is explicit that it is not a recognized diagnosis, and no cortisol test — blood, saliva or urine — confirms it; persistent fatigue deserves a real evaluation (thyroid, blood count, iron, sleep, mood) rather than a cortisol panel sold to explain it. The cortisol test page covers the morning reference range.

Yes, when a clinician orders it for symptoms that suggest an adrenal disorder — unexplained fatigue with low blood pressure or weight loss, salt craving, skin darkening (for insufficiency); rapid central weight gain, new high blood pressure or diabetes, easy bruising, purple stretch marks, muscle weakness (for Cushing's) — against your copay or deductible, and the specialty tests and the ACTH stimulation test are covered on the same basis once a first-line result is ambiguous. Cortisol is not a preventive service, so there is no no-cost version, and a "stress" or "adrenal" check without symptoms is generally denied as not medically necessary. If you are paying any part yourself, a morning serum cortisol at an independent lab costs less than most hospital labs' negotiated rates for the same CPT code (82533). HSA and FSA funds pay in every setting.

The first hidden cost is the wrong test: a $27 morning cortisol bought to investigate weight gain and high blood pressure answers nothing about Cushing's, and the right test still has to be done. The second is the wrong time: a cortisol drawn at 2 PM is read against a morning range and looks falsely low, which buys a repeat draw or an unnecessary stimulation test — TestWell's requisition specifies a 7–9 AM draw for this reason, and if your schedule will not allow it, the afternoon cortisol ($34.99) is the correctly ranged alternative. The third is interpretation without context: cortisol is read alongside sodium, potassium and glucose (a CMP, $22.99), DHEA-sulfate ($32.99) for the other adrenal hormone, and often TSH ($26.99) because thyroid disease is the more common explanation for the same symptoms. A low or high result is a reason to see a clinician — ideally one who can order the stimulation or suppression test on the same visit — not to re-test online until the number looks better.

• Fatigue, low blood pressure, salt craving, or you have stopped a steroid: a morning serum cortisol ($32.99 all-in through TestWell), drawn 7–9 AM; add a CMP and DHEA-S to the same draw so the result has context.
• Weight gain, new high blood pressure or diabetes, bruising, stretch marks: skip the blood test and ask a clinician for a Cushing's screen (late-night salivary or 24-hour urine cortisol) — the morning level will not answer it.
• You want to see your daily rhythm: the AM ($26.99) and PM ($34.99) cortisol tests on two draws from one order.
• Insured with symptoms: have your clinician order it with a diagnosis code and draw it at an independent lab; your copay may be the cheapest route and it sets up the next test if needed.
• On the pill or hormone therapy: tell whoever reads the result — oral estrogens raise total cortisol — or ask whether to test at all.
• Avoid: buying a cortisol test to confirm "adrenal fatigue"; the money is better spent on TSH, a CBC and ferritin.

Every test is drawn at Quest or Labcorp and carries one $6 lab processing fee per order, charged once however many tests you add. Cortisol, AM $26.99 (Quest 367 / Labcorp 104018; CPT 82533; draw 7–9 AM) — Quest Health $79. Cortisol, PM $34.99. Context tests: CMP $22.99, DHEA-Sulfate $32.99, TSH $26.99. A licensed physician authorizes the order, the requisition is emailed with the draw-time instruction, most locations take walk-ins, and results post to your account in 2–4 business days with the time-specific reference range and a plain-language summary to bring to your clinician. The salivary, urine and stimulation tests are clinic-ordered and are not sold here. The cortisol cost page tracks competitor prices month to month.
