Day/Night Cortisol Test from Saliva

The cortisol test from saliva – is a modern, non-invasive method designed to assess the stress level in the body and the functionality of adrenal activity. Cortisol is the main stress hormone produced by the adrenal cortex – its level fluctuations can reflect not only stress response but also deeper hormonal system disorders.

This test is particularly valuable:

• In assessing the body's response to stress – both acute and chronic;
• In investigating potential adrenal dysfunctions, such as hypercortisolism (Cushing's syndrome) or hypocortisolism (Addison's disease);
• In conducting long-term observations or studying daily cortisol rhythms, as samples can be collected multiple times a day – in the morning, afternoon, and evening.

Why test from saliva?
Since the saliva sample is non-invasive, painless, and easy to collect, this method is particularly convenient:

• for children,
• for sensitive patients,
• for conducting tests at home,
• when studying cortisol daily fluctuations, which can be distorted by the stress of blood collection.

Benefits:

• Allows for accurate assessment of free (active) cortisol concentration;
• Does not require special equipment for sample collection;
• Ideal for both diagnostics and functional health monitoring – especially in cases of chronic fatigue syndrome, insomnia, anxiety or depressive disorders, experiencing constant stress, or suspecting hormonal imbalance.
