Heavy metals and essential elements testing helps identify toxic exposures and nutrient imbalances that can impact hormones, metabolism, immune function, and neurological health. Using convenient dried urine and dried blood spot methods, this testing provides a comprehensive view of elemental status, enabling more personalized strategies for detoxification, nutritional support, and long-term wellness.

Cortisol testing helps evaluate how the body responds to stress by measuring daily hormone patterns linked to energy, sleep, mood, and immune balance. Through saliva and blood spot methods, clinicians can identify adrenal and HPA-axis imbalances early, enabling more personalized strategies to address fatigue, burnout, and stress-related health concerns.

Androgen metabolite testing provides deeper insight into how the body produces, converts, and eliminates hormones such as testosterone and DHT. By analyzing urine metabolites rather than single hormone levels, clinicians gain a more complete picture of hormonal balance, helping guide personalized treatment, monitor therapy effectiveness, and detect imbalances linked to conditions like PCOS, acne, hair changes, and metabolic issues.

Urine, serum, plasma, whole blood, red blood cells, feces, hair, fingernails—the list of biological samples used for element testing is long. But choosing the right sample type is one of the most critical decisions in producing results that are clinically meaningful and scientifically valid.

Learn the science of saliva testing, how it measures bioavailable hormones, and why it’s trusted by patients, clinicians, and wellness experts.
