The Oxidative Stress Profile is a urine and saliva test that evaluates oxidative damage, antioxidant capacity, and cellular resilience, key factors in understanding the biological rate of aging and foundational elements of longevity. Using advanced liquid chromatography–mass spectrometry (LC-MS/MS), the test measures 16 urinary markers of oxidative damage to DNA, RNA, proteins, and lipids. It also analyzes 32 antioxidant-related genetic variants via RT-PCR to assess your inherited capacity to neutralize free radicals. This test provides clinical insight into free radical activity, inflammation, and mitochondrial function, helping guide targeted strategies to reduce oxidative stress and support long-term cellular health.
