LipoFit by NMR
Also known as: NMRLIPFIT
Use
The LipoFit by NMR test is used for assessing LDL particle number in high-risk patients, such as those with type 2 diabetes mellitus, where LDL particle number is being used to guide therapy. It is not recommended for cardiovascular disease risk assessment in general populations, as the preferred test is the regular Lipid Panel.
Special Instructions
Patients should fast for 12 hours prior to specimen collection. The specimen must be collected in a Greiner Bio-One Clot Activator Tube, with a minimum volume of 2 mL. Mixing by gentle inversion after collection and proper separation from cells within 8 hours is critical.
Limitations
The LipoFit by NMR has not been cleared or approved by the US Food and Drug Administration. This test is a Laboratory Developed Test and is performed in a CLIA certified laboratory for clinical purposes. Furthermore, the methodology employed includes quantitative nuclear magnetic resonance spectroscopy combined with quantitative enzymatic assays.
