Several primary prevention and secondary prevention scenarios exist where patients would receive greater benefit from quantitative lipoprotein testing than cholesterol information. Primary prevention patients with a high-risk history, patients with isolated lipid abnormalities such as low HDL cholesterol levels or elevated triglycerides, and patients at or near an NCEP cutpoint would be candidates for the NMR LipoProfile. Secondary prevention patients may benefit from quantitative testing when those patients have few or no modifiable risk factors, have diabetes, continue to have recurrent events, and finally those at or near an NCEP cutpoint where the clinician needs more information to make an informed decision. The NMR LipoProfile is not needed when the clinician would initiate treatment based on excessively elevated lipid values. Test sent to Mayo Medical Laboratories; performed by LabCorp Burlington.
