Blood test measuring S-Adenosylmethionine (SAMe), S-Adenosylhomocysteine (SAH), and their ratio to assess methylation status.
Specialty biomarker testing measures advanced markers that go beyond standard blood panels to provide deeper insight into specific biological pathways. These tests are commonly used in functional and integrative medicine to identify root causes of symptoms, assess cellular health, and guide personalized treatment protocols. Markers like IGF-1 reflect growth hormone activity and aging, lipoprotein(a) reveals inherited cardiovascular risk invisible to standard lipid panels, and neurotransmitter profiles can explain mood and cognitive symptoms. Results enable highly targeted interventions that standard tests would miss.
Key Details
Who Is This For?
People working with functional or integrative medicine practitioners. Those seeking root-cause analysis beyond standard blood work. Longevity enthusiasts tracking advanced biomarkers. Anyone with persistent symptoms despite normal standard labs.
What's Included
Preparation Required
Fasting may be required depending on the specific marker. Follow your clinic's instructions. Some tests require morning samples for accurate results. Bring a list of all supplements — many affect these markers.
Biomarkers Tested
3A universal methyl donor involved in methylation reactions crucial for DNA synthesis, mental health, and detoxification.
Precursor to homocysteine and byproduct of SAMe-dependent methylation; elevated levels indicate impaired methylation.
Reflects the balance between methylation reactions; provides insights into cellular health, metabolism, and disease.
