Patient Preparation: Patient should be fasting for eight hours.

Test Includes: The reflex criteria below are in effect. • If triglycerides are >800, the LDL cholesterol will reflex to the direct LDL at an additional charge. • If LDL direct is <130, will reflex to NMR Lipoprotein Analysis by NMR without IR (insulin resistance) markers performed at an additional charge. • If LDL calculation is <130, will reflex to NMR Lipoprotein Analysis by NMR without IR (insulin resistance) markers performed at an additional charge. Special Instructions: Note: Two specimens must be included with all test requests. See requirements under the Specimen section below. Specimen: Lipid profile: Serum (preferred) or plasma and lipoprotein reflex: Spun NMR LipoTube (preferred), serum from a plain red-top tube, or plasma from a lavender-top (EDTA) tube. Ship with frozen cool packs. Volume: 2 mL (each tube) Minimum Volume: 1 mL (each tube) Container: Lipid profile: gel-barrier transport, green-top (heparin), or lavender-top (EDTA) tube andlipoprotein reflex: NMR LipoTube (black-and-yellow-top tube), plain red-top tube, or lavender-top (EDTA) tube. Both specimens must be submitted with all requests. Collection: Lipid profile: Separate serum or plasma from cells within 45 minutes of collection. Lipoprotein reflex: Collect specimen in NMR LipoTube (black-and-yellow-top tube), which is the preferred specimen, or plain red-top tube. Gently invert tube to mix contents and allow specimen to clot for 30 minutes before centrifugation. Centrifuge specimen immediately after clotting to separate serum from the red cells. If the sample cannot be centrifuged immediately, it must be refrigerated at 2°C to 8°C and centrifuged within 24 hours of collection. Do not open NMR LipoTube. Serum or plasma drawn in gel-barrier collection tubes other than the NMR LipoTube should not be used. Pipette separated serum from plain red-top tube to a plastic transport tube. Separate plasma from lavender-top (EDTA) tube immediately after the collection and transfer to a plastic transport tube for shipment to the laboratory. Ship with frozen cool packs. Storage Instructions: Lipid profile: Room temperature: Gel-barrier tube, green-top (heparin) tube, or lavender-top (EDTA) tube. Stable at room temperature for six hours or refrigerated for 10 days. Frozen is not acceptable. Lipoprotein reflex: Refrigerate: NMR LipoTube (black-and-yellow-top tube), serum transport tube, or plasma transport tube. Do not freeze sample. Refrigerate as soon as possible and do not store at room temperature. Stable refrigerated for six days
