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.

The ZRT Laboratory CardioMetabolic Profile is a convenient finger-prick blood test designed to detect early warning signs of diabetes and cardiovascular disease. By measuring key markers such as insulin, cholesterol, triglycerides, HbA1c, and inflammation, it provides a comprehensive view of heart and metabolic health, supporting early intervention and personalized preventive care.

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.
