Doctor's Data Inc. (DDI) offers a spectrum of tests designed to evaluate the exposure to environmental toxicants and markers of the body's capacity for endogenous detoxification.  The World Health Organization (WHO) estimates that about a quarter of the diseases facing mankind today occur due to prolonged exposure to environmental pollution.   Today we'll offer insight into our unique Methylation Profile.

DDI’s Methylation Profile  

Normal metabolism of methionine is critical for cellular transmethylation of DNA, proteins and neurotransmitters. Aberrant methionine metabolism can occur in anyone – at any age – and can be associated with a variety of conditions, including cardiovascular disease and cancer.

The methylation profile provides a functional assessment of the phenotypic expression of common SNPs (MTHFR, MS, CBS) by evaluating the plasma levels of methionine, cysteine, SAM, SAH, homocysteine and cystathionine, and provides the key methylation index ratio of SAM to SAH.  The results can be used to determine appropriate nutritional support to normalize metabolism.
