Useful for:

• Assessment and management of a patient's risk for atherosclerotic cardiovascular disease


• Identifying residual risk that may be present in some patients on cholesterol targeting treatment

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.

Spun NMR LipoTube (preferred), serum from a plain red-top tube, plasma from a lavender-top (EDTA-no gel), OR green-top (heparin-no gel) tube. Keep refrigerated and SHIP WITH FROZEN COOL PACKS.
