Understanding the Cortisol
The Cortisol Test measures the level of cortisol in your blood, a hormone produced by the adrenal glands that’s often called the body’s primary stress hormone. Cortisol helps regulate blood sugar, blood pressure, metabolism, and your response to stress, and it follows a natural daily rhythm: levels are highest in the morning and taper through the day. At our Ashburn lab in Goose Creek Village, this $59 blood test is available on a walk-in basis with the doctor’s order already included.
Because cortisol rises and falls on a predictable cycle, timing is essential to a meaningful result. This test is best collected in the morning, when cortisol naturally peaks, which is why providers often ask for an early draw, typically before mid-morning. A morning reading gives the clearest baseline for comparison and is the standard starting point when looking into adrenal function.
People test cortisol for a variety of reasons, often to gather objective data when investigating persistent fatigue, unexplained weight changes, or symptoms a provider wants to evaluate as part of an adrenal workup. A single cortisol value is one piece of a larger puzzle, so your provider may pair it with other hormone markers or repeat testing. Whatever the result, you’ll receive a clear report to bring to your physician for interpretation.

What to expect
From check-in to results — what your visit looks like
Most visits take under 15 minutes. Here’s the full arc, start to finish.
How to prepare
Timing matters more for cortisol than for most tests. Because levels peak in the morning, plan to come in early in the day, ideally before mid-morning, and let us know your draw time so it can be noted on the report. Try to arrive calm and rested, since acute physical or emotional stress, intense exercise, and even significant sleep disruption can raise cortisol. Mention any medications you take, including steroids and certain hormonal products, as these can affect the reading. Bring a photo ID, and call us if you’d like help scheduling an early slot.
During your visit
Your visit is short and simple. After checking in at our Goose Creek Village location, a technician draws a single small blood sample from your arm, usually in a minute or two, and notes the time of the draw since it matters for cortisol. Most clients are in and out within about 10 to 15 minutes. No appointment is strictly required for most tests, though booking an early-morning slot ahead of time helps us capture the peak window and greet you faster.
Getting your results
Your cortisol result is typically ready in 24 to 72 hours and is posted to your secure online patient portal for private viewing and download. If you prefer, we can fax the report directly to your doctor’s office. Because cortisol shifts with the time of day, stress, medications, and other factors, any abnormal result should be reviewed by a licensed provider, who can interpret it in context and decide whether additional or repeat testing is warranted.

FAQ
Cortisol Test — what people ask
Specific questions about the cortisol test. For anything not covered, call 571-500-7030.
Why does the test need to be done in the morning?
Cortisol follows a daily rhythm and naturally peaks in the morning, then declines through the day. A morning draw, usually before mid-morning, gives the clearest baseline, which is why providers typically request an early-day sample for this test.
Can stress on the day of my test change the result?
Yes. Acute physical or emotional stress, intense exercise, and poor sleep can temporarily raise cortisol. Arriving calm and rested helps, and noting the draw time and any stressors lets your provider interpret the result more accurately.
Do I need a referral for a cortisol test in Ashburn?
No referral is needed. The required physician’s order is included with the $59 test, so you can request it directly at our Goose Creek Village location and share the report with your own provider afterward.
