The NMR LipoProfile® with Lipids + IR + Gph is an advanced blood test ordered through diagnostic providers like Labcorp. It provides a comprehensive analysis of cardiovascular risk and metabolic health by analyzing the specific particle count of cholesterol carriers and assessing insulin resistance. [1, 2, 3]
Breakdown of the Test Name
  • NMR LipoProfile: Uses Nuclear Magnetic Resonance (NMR) spectroscopy to count the actual number of lipoprotein particles (like LDL-P) and determine their size. This differs from a standard test, which only measures the total weight of cholesterol carried inside those particles.
  • Lipids: Includes the standard lipid panel measurements. It tracks total cholesterol, LDL-C (“bad” cholesterol), HDL-C (“good” cholesterol), and triglycerides.
  • IR (Insulin Resistance): Provides the Lipoprotein Insulin Resistance Index (LP-IR) score. This metric uses particle sizes to score metabolic health on a scale from 0 (sensitive) to 100 (resistant), indicating early type 2 diabetes and metabolic syndrome risk.
  • Gph (Graph): Specifies that the finalized laboratory document includes visual color charts and historical graphing. This helps doctors and patients easily track changes and risk categories over time. [1, 2, 3, 4, 5, 6]
Clinical Importance
The panel identifies “hidden” heart disease risk. Individuals can display normal cholesterol weights (LDL-C) on a standard test but possess a dangerously high number of small, dense LDL particles (LDL-P). These small particles easily penetrate the arterial walls to form plaque. [1, 2]
To help interpret your specific report, what are your LDL-P or LP-IR numbers? If you are taking a statin or diabetes medication, sharing that can help contextualize your results. [1, 2]

Abstract

Identifying risk factors for cardiovascular diseases in patients is key to reducing their resulting morbidity and mortality. Currently, risk factors are assessed using parameters that include and emphasize the role of the level of cholesterol carried by lipoproteins. Most providers focus on targeting cholesterol levels in patient management. However, recent research shows that lipoprotein particle number is more predictive of cardiovascular risk than cholesterol levels. The Nuclear Magnetic Resonance (NMR) LipoProfile test assesses the number of lipoprotein particles, sizes of lipoproteins, levels of cholesterol, and patient risk categories. Furthermore, it enables the identification of patients with underestimated cardiovascular risks-those with a discordant high number of low-density lipoprotein (LDL) particles (LDL-P) despite low cholesterol levels. While the NMR LipoProfile test requires a higher cost and longer waiting time for results in comparison to the lipid panel test, its advantages cannot be ignored. This review article focuses on exploring the routine use of NMR LipoProfile in clinical practice.

Highlights

  • – Lipoprotein particle number predicts cardiovascular risk better than cholesterol.
  • – Nuclear magnetic resonance LipoProfile assesses lipoprotein particle number.
  • – Using nuclear magnetic resonance LipoProfile clinically could improve patient care.

Introduction

NMR LipoProfile is a fairly new and more accurate method of assessing cardiovascular risk in individuals than the more widely used lipid panel test. It differs from the lipid panel in that it measures other parameters that are indicative of cardiovascular risk status such as lipoprotein particle numbers. This paper aims to describe the NMR LipoProfile and discuss its relevance in cardiovascular settings.

LDL-P could either be small or large and situations, where small LDL-P are abundant, may be associated with increased atherogenic risk than situations where large LDL particles are plentiful (–). Small LDL-P occur as a result of metabolic action on lipoproteins rich in triglycerides such as VLDL. They are also predominant in individuals with hyperbetalipoproteinemia and those with insulin resistance including patients diagnosed with type II diabetes mellitus, hypertriglyceridemia, obesity, and hypertension. Small dense LDL is thought to be more atherogenic because they are better able to penetrate the endothelial cell barrier and enter the intima. They are more susceptible to oxidation, bind to proteoglycans in the arterial wall, and have a longer half-time in the circulation than large LDL-P. Other distributions of lipoprotein subclasses that confer an increased cardiovascular risk include low levels of HDL particles and high levels of VLDL. In CVD assessment, lipoproteins are used in addition to other indicators of cardiovascular risk such as gender, smoking status, and diabetes (, ). During risk management, treatment goals and success hinge on pre-set lipoprotein levels, and in this case, clinical decision-making is almost solely dependent on measured lipoprotein levels (, ).

Although both lipoprotein cholesterol and lipoprotein particle levels have been known to confer risk, LDL-P number/concentration has been identified in multiple studies as the strongest predictor of future cardiovascular events when compared to LDL cholesterol (LDL-C) and apolipoprotein B (, –). Data analysis from the Framingham study showed an association between LDL particle number and increased cardiovascular risk in both men (HR = 1.24: 1.10–1.39) and women (HR = 1.33: 1.17–1.50). While the association between LDL-C and increased cardiovascular risk was only seen in women (HR = 1.18: 1.02–1.37) and not in men (HR = 1.06: 0.94–1.20) (). Apolipoprotein B levels and LDL-P numbers are more strongly associated with atherosclerotic cardiovascular risk score (ASCVD) than LDL-C, particularly when the levels of LDL-C and Apolipoprotein B levels or LDL-P numbers are discordant. Guidelines for treatment include recommendations for specific LDL-C levels as the goal of treatment, however, LDL-P numbers may be a better indicator of risk than LDL-C. Focusing on the LDL-P number as the treatment target may be more helpful in providing individualized treatment modalities, as it could potentially distinguish patients whose risks have not been adequately managed from those with an adequate response to therapy ().

A key subset of individuals who will likely benefit from lipoprotein particle measurements are those with discordance (having low LDL-C but high LDL-P) (, ). One study conducted with a community sample showed that although a large percentage of individuals (79%) with low LDL-C had corresponding low LDL-P numbers, about 21% had high LDL-P numbers (). The rates may even be higher in clinical samples as evidenced by a finding of discordance in approximately 63% of patients in a lipid clinic (). Factors associated with discordance include male gender and smoking status, lipid-lowering therapy, and patients approaching their target LDL-C. As the number of LDL lower with treatment, LDL particles get more cholesterol depleted leading to this discordance (). Furthermore, those with this discordance had higher CVD risk including a lower probability of event-free survival and incident CVD compared to concordant individuals (, ). In a study where LDL-C and LDL-P were associated with incident CVD overall, among those with discordant levels, only LDL-P was significantly associated with incident CVD (HR = 1.45: 1.19–1.78) unlike LDL-C (HR = 1.07: 0.88–1.30) (). Because patients with discordance tend to have higher CVD risk, they will likely benefit more from intensive therapy targeted toward lowering their LDL particle number than their LDL-C level (, ).
