Lipoprotein Analysis (LDL-P, HDL-P, LDL Size), Expanded

NMR LipoProfile Without IR (insulin resistance) Markers



Test Number: 884247 CPT Code: 80061; 83704

Test Includes: Insulin resistance calculation; lipoprotein particle number; lipoprotein subfractions; standard lipid panel (total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides)



Specimen: Spun NMR LipoTube or serum from a plain red-top tube



Volume: 2 mL



Minimum Volume: 1 mL



Container: NMR LipoTube (black- and-yellow-top tube) or plain red-top tube



Collection: Patient should be fasting 12 to 14 hours. Collect specimen in NMR LipoTube (black-and-yellow-top tube) or plain red-top tube. Gently invert tube to mix contents and allow specimen to clot for 30 minutes before centrifugation. Specimen should be kept refrigerated and centrifuged within 24 hours of collection. Centrifuge specimen for 15 minutes at 3000 rpm. To preserve specimen integrity, centrifuged specimen can be kept refrigerated for four days before shipping and then it must be shipped with frozen cool packs. Do not freeze and do not store at room temperature. Do not open NMR LipoTube. Pipette separated serum from plain red-top tube to a plastic transport tube.



Storage Instructions: Sample must be kept refrigerated. Do not freeze sample and do not store at room temperature. Stable at room temperature for six hours or refrigerated for 10 days. Frozen is not acceptable.



Patient Preparation: Patient should be fasting for 12 to 14 hours.



Causes for Rejection: Unspun LipoTube or unseparated plain red-top tube; gross hemolysis; serum more than 10 days old; specimen in inappropriate container; frozen specimen; specimen stored at room temperature; EDTA plasma.



Limitations: If triglyceride level is >400 mg/dL, LDL cholesterol will not be calculated.



Methodology: Nuclear magnetic resonance (NMR)
