Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
ACTH (Adrenocorticotropic Hormone)
ACTH is a pituitary hormone that controls cortisol production by your adrenal glands. Monitoring ACTH levels as part of your health routine may help provide early insights into how well your stress response system is functioning.
Reference Ranges
Reference ranges may vary between laboratories. When you order a test, a BIG-registered doctor assesses your personal results in context. For treatment decisions, discuss your results with your GP.
What It Measures
This test measures the level of ACTH in your blood. Results may help evaluate how well your pituitary gland communicates with your adrenal glands to regulate cortisol production and maintain hormonal balance throughout the day.
Why It Matters
Tracking ACTH levels may help identify early signs of pituitary or adrenal imbalance before symptoms become pronounced. Understanding your baseline could support proactive health decisions. Your healthcare provider can guide you through the results.
When to Test
ACTH testing is typically recommended in the early morning, when levels are naturally at their peak. Your healthcare provider may suggest this test if you show signs of adrenal or pituitary dysfunction, or unexplained fatigue.
