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 hormone from the pituitary gland that tells your adrenal glands to produce cortisol. Understanding your ACTH levels may offer insights into how your body manages stress and supports your hormonal well-being.
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
ACTH influences cortisol production, which may affect your menstrual cycle, mood, and energy levels. Monitoring this marker could help identify stress-related hormonal imbalances. Discuss any concerns with your healthcare provider for personalized support.
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.
