NMR LipoProfile® With Insulin Resistance Markers Without Lipids (Without Graph)
Use
NMR LDL-P is a management tool used in appropriate risk-risk patients (type 2 diabetes mellitus, metabolic syndrome, CVD risk equivalent, statin-treated patients) to adjudicate response to treatment and guide adjustment in therapy. It is used in conjunction with other lipid measurements and clinical evaluation to aid in the management of lipoprotein disorders associated with cardiovascular disease.
Special Instructions
Patient should be fasting for eight hours prior to specimen collection. Centrifuge the specimen within two hours of collection. Keep refrigerated and ship with frozen cool packs. Collect in NMR LipoTube is preferred; do not open NMR LipoTube.
Limitations
This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the FDA. Results may be less accurate if the patient is non-fasting as the LP-IR score is affected by such conditions. The test may not accurately reflect insulin resistance and diabetes risk if certain parameters associated with the LP-IR score are not followed.

Volume

Minimum Volume
1 mL
Container
NMR LipoTube (black-and-yellow-top tube), plain red-top tube, lavender-top (EDTA-no gel) tube, or green-top (heparin-no gel) tube
Collection Instructions
Collect specimen in NMR LipoTube (black-and-yellow-top tube), which is the preferred container. Plain red-top, green-top (heparin-no gel) or lavender-top (EDTA-no gel) tubes also are acceptable. Serum or plasma drawn in gel-barrier collection tubes other than the NMR LipoTube should not be used. Gently invert tube eight to 10 times to mix contents and allow specimen to clot for 30 minutes upright at room temperature prior to centrifugation. Centrifuge specimen within two hours of collection at 1600 to 1800 xg for 10 to 15 minutes to separate serum/plasma from the red cells and avoid red cell contamination during shipment.
Patient Preparation
Patient should be fasting for eight hours.
Storage Instructions
Refrigerate all acceptable tube types as soon as possible after centrifugation and within 24 hours of collection. Keep refrigerated prior to shipment, and ship on frozen cool packs. Do not store at room temperature. Do not freeze the sample.
Causes for Rejection
Unspun specimens; plasma/serum contaminated with red cells; citrated plasma (light blue-top tube); gross hemolysis; specimen received in inappropriate container; specimen stored at room temperature for more than a total preanalytical time of 24 hours; specimen more than six days old.
