Cortisol (free)
Free Cortisol refers to the unbound, biologically active form of cortisol circulating in the body. Unlike total cortisol, which includes both bound and unbound hormone, free cortisol represents the fraction that is available to tissues and can directly influence stress response, metabolism, immune function, and energy levels. Measuring free cortisol provides a more accurate reflection of how the body is responding to physical and emotional stress. It is commonly assessed in urine or saliva samples and is particularly relevant in evaluating adrenal function and circadian rhythm imbalances.
Description
Individuals experiencing chronic stress, fatigue, anxiety, or symptoms of adrenal dysfunction would benefit from cortisol testing. It’s also helpful for those with irregular sleep patterns, weight changes, or ongoing health issues linked to stress.
High Cortisol:
-
- Weight gain, especially in the abdomen
- Insomnia
- Anxiety and depression
- High blood pressure
- Muscle weakness
Low Cortisol:
-
- Chronic fatigue
- Muscle weakness
- Weight loss
- Low blood pressure
- Mood swings
Saliva testing for cortisol measures free, active hormone levels, reflecting the body’s immediate response to stress. Blood tests measure total cortisol, including both bound and unbound cortisol, giving a broader view of adrenal function over time.
Cortisol levels fluctuate throughout the day, peaking in the morning and gradually declining. Measuring several times captures this natural rhythm, providing a more accurate assessment of adrenal function and stress response.

7 measurements
GetTested’s cortisol test measures bioavailable and free cortisol on seven occasions during a day. Cortisol is released in response to physical or mental stress. Produced by the adrenal glands, cortisol boosts physical and mental performance under short-term stress. However, consistently high cortisol levels can harm your health, while too low levels can also be problematic. This test is particularly useful for individuals experiencing chronic stress, fatigue, or other stress-related symptoms.

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the Europe. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.
