Testosterone and Cortisol Blood Test
Testosterone and Cortisol Blood Test
The Testosterone and Cortisol Blood Test is a specialist diagnostic tool designed to evaluate two of the body's most influential hormones: testosterone and cortisol. These hormones play key roles in regulating energy, stress, metabolism, mood, sexual function, and muscle maintenance. Understanding their levels provides valuable insight into the body's endocrine balance and can help identify underlying health conditions that may otherwise go undetected. This test is widely utilised by GPs, endocrinologists, and integrative medicine practitioners to investigate symptoms such as persistent fatigue, mood swings, low libido, and decreased physical performance. It is supported by research from leading institutions including Harvard Medical School, Oxford University, and clinical findings published in journals such as The Lancet Diabetes & Endocrinology and The Journal of Clinical Endocrinology & Metabolism. Numerous studies have shown that imbalances in testosterone and cortisol are associated with a wide range of health concerns—from adrenal dysfunction and stress-related disorders to age-related hormonal decline and metabolic issues.
What Does It Test For?
This blood test measures circulating levels of testosterone and cortisol, providing a snapshot of how the body manages both anabolic and catabolic processes. These two hormones operate in a delicate physiological balance—testosterone supports growth, repair, and vitality, while cortisol helps the body manage stress, inflammation, and metabolic demands. The test is commonly requested to assess for conditions such as low testosterone (hypogonadism), adrenal fatigue or insufficiency, chronic stress, or Cushing’s syndrome. It is also valuable for individuals undergoing hormone therapy, athletes monitoring recovery and training load, or anyone experiencing symptoms related to hormonal imbalance. By evaluating both hormones together, clinicians can better understand how the body responds to internal and external stressors and determine whether intervention is needed to restore hormonal equilibrium.
