Medical Professionals need BETTER Laboratory Tests

Medical professionals and their patients depend on laboratory tests to monitor biochemical changes.   Information gained from laboratory tests guide the medical professional in the selection of the best intervention for each patient.

The Longevity Test provides medical professionals with laboratory evidence of lipid changes in sub-clinical dyslipidemia.  Medical professionals should see a need for the Longevity Test as they increase the use of nutraceuticals in coronary artery disease prevention and wellness enhancement.   Current laboratory methods for fractionating LDL and/or HDL cholesterol particles, at times, provide conflicting results on the same patients.  Monitoring changes in the size distribution of HDL and LDL particles in the blood is crucial to your ability to monitor positive changes in these particles away from disease and toward longevity.

The Longevity Test was designed to monitor small but significant changes by comparing pre- and post- intervention samples in side-by-side testing.   The Longevity Test uses gradient gel electrophoresis to separate cholesterol containing particles into specific groups based on particle size.

This separation is accomplished by placing several microliters of serum or EDTA plasma on a gradient electrophoresis gel.  Electricity is used to cause the cholesterol particles to migrate through the gel.  The gel has the largest pores at the top and the pore size gets smaller as the sample travels down the gel. After separation, the HDL and LDL particle size distributions are identified using digital imaging analysis to measure both the distance traveled and the intensity of the particles.  The HDL and LDL distributions are divided into measurement fractions for analysis.  The Longevity Test increases the number of analyzed cholesterol fractions by 500% over other LDL fractionation tests.
