How to Prepare for the Test
Staying hydrated by drinking plenty of water helps ensure accurate results. Avoiding stress and intense physical exercise for at least 24 hours before testing is important, as both can raise cortisol levels. Limiting caffeine and alcohol intake is recommended, as stimulants can interfere with hormone balance. Informing your doctor about any medications, including steroids, birth control, and antidepressants, is necessary because some drugs affect cortisol production.
How the Test is Done
A healthcare professional will collect a blood sample from a vein in the arm. If using an at-home test kit, a finger-prick sample may be required. The sample is then sent to a certified laboratory for analysis.
Understanding Your Results
Normal cortisol levels range from 5 to 25 mcg/dL in the morning and 3 to 10 mcg/dL in the afternoon. Chronic stress, adrenal gland disorders, high blood pressure, obesity, or medication side effects may cause high cortisol levels. Low cortisol levels can result from Addison’s disease, pituitary gland disorders, or sudden withdrawal from corticosteroid medications.

What to Do After the Test?
Discussing results with a doctor is essential to understand any imbalances. Follow-up testing, such as a 24-hour urine cortisol test or ACTH stimulation test, may be required for further evaluation. If needed, lifestyle adjustments, including stress management techniques, dietary changes, or medications, may be recommended.
Tips for Maintaining Healthy Cortisol Levels
Managing stress through meditation, yoga, or deep breathing exercises can help keep cortisol levels stable. Regular exercise in moderation supports overall hormonal balance, but excessive workouts should be avoided. Eating a balanced diet with whole foods, lean proteins, and healthy fats promotes adrenal health. Getting seven to nine hours of sleep each night is essential for hormone regulation. Staying hydrated throughout the day supports overall well-being and optimal cortisol levels.
Final Thoughts
Monitoring cortisol levels helps detect adrenal imbalances and supports long-term health. If symptoms of hormonal imbalance appear, consulting a healthcare provider for further evaluation and treatment is recommended.
