What is NMR lipoprotein testing?
The NMR LipoProfile® test is an FDA-cleared blood test that directly measures the amount of LDL circulating in the body. “LDL” is low-density lipoprotein and has long been recognized as a major causal factor in the development of heart disease.
What is NMR lab test?
The NMR LipoProfile test is an advanced cardiovascular diagnostic test that uses nuclear magnetic resonance (NMR) spectroscopy to provide rapid, simultaneous and direct measurement of LDL particle number and size of LDL particles, and also direct measurement of HDL and VLDL subclasses.
What is lipoprotein fractionation NMR?
Lipoprotein Fractionation, NMR with Lipid Panel (Triglycerides/HDL-C) – The Lipoprotein Fractionation, NMR test is used to help assess the risk for cardiovascular disease (CVD) in patients with intermediate or high risk based on traditional or emerging risk factors, and to assess therapeutic response in patients …
How long does an NMR test take?
For a simple 1D spectrum of a small molecule data can typically be collected in 15 minutes. For very insensitive 3D and 4D NMR experiments a single experiment may take a week.
What does NMR measure?
NMR is an abbreviation for Nuclear Magnetic Resonance. An NMR instrument allows the molecular structure of a material to be analyzed by observing and measuring the interaction of nuclear spins when placed in a powerful magnetic field.
What does high LDL-P mean?
Studies have shown that LDL-P more accurately predicts risk of cardiovascular disease than LDL-C. Researchers think that increased LDL-P could be one of the reasons that some people have heart attacks even though their total cholesterol and LDL cholesterol levels are not particularly high.
How much does an NMR blood test cost?
The NMR LipoProfile test costs around $100. Medicare covers the cost of the test and most private insurance providers cover a portion, as well.
How does NMR analysis work?
How Does NMR Actually Work? When molecules are placed in a strong magnetic field, the nuclei of some atoms will begin to behave like small magnets. The resonant frequencies of the nuclei are then measured and converted into an NMR spectrum that displays all of the right frequencies as peaks on a graph.
Why is NMR insensitive?
NMR is an insensitive technique because it requires a relatively large amount of sample to make a measurement. For example, a mass spectrometry experiment requires about 1 µg of sample, but an NMR experiment requires 5 to 25 mg of sample.
What is LDL C vs LDL-P?
LDL-P is often used to get a more accurate measure of LDL due to the variability of cholesterol content within a given LDL. Studies have shown that LDL-P more accurately predicts risk of cardiovascular disease than LDL-C.
How is the lipoprotein fractionation, NMR test used?
Lipoprotein Fractionation, NMR – The Lipoprotein Fractionation, NMR test is used to help assess the risk for cardiovascular disease (CVD) in patients with intermediate or high risk based on traditional or emerging risk factors, and to assess therapeutic response in patients undergoing lipid-lowering therapy.
Which is the best container for NMR lipoprofile?
NMR LipoTube (black-and-yellow-top tube) is the preferred container, plain red-top tube, lavender-top (EDTA-no gel) tube, or green-top (heparin-no gel) tube. Collection Collect specimen in NMR LipoTube (black-and-yellow-top tube), which is the preferred container.
What is the lab code for the lipoprofile test?
NMR LipoProfile Blood Test. The NMR LipoProfile test is the only test that will report LDL particle number and size. Quest. LabCorp. Test Code: 884247. Also Known As: Cholesterol, Lipoprotein Analysis (LDL-P, HDL-P, LDL Size), Expanded. Methodology: Nuclear magnetic resonance (NMR)
Which is the only test that will show LDL particle size?
The NMR LipoProfile test is the only test that will report LDL particle number and size. Quest. LabCorp. Test Code: 884247. Also Known As: Cholesterol, Lipoprotein Analysis (LDL-P, HDL-P, LDL Size), Expanded. Methodology: Nuclear magnetic resonance (NMR)
