SpectraCell's Cardiac Nexus profile combines their advanced LPP® technology with an MTHFR gene test. LPP® (Lipoprotein Particle Profile) reports the size and type of your lipoproteins, which is recognized as a superior tool in diagnosing problems of cholesterol and lipid metabolism. The patented LPP® test addresses two key issue in heart health missed by other technologies: (1) who is at higher cardiovascular risk and (2) what to do about it. The MTHFR test determines which copy of the MTHFR gene you carry. This gene controls a key enzyme (called Methylenetetrahydrofolate Reductase, or MTHFR). If you carry certain copies of this gene, you may be predisposed to specific B vitamin deficiencies, which overwhelming evidence confirms, is intimately linked to methylation disruptions that impact cardiovascular, neurological, reproductive, and detoxification systems.
