Preferred Specimen

1 mL serum collected in a red-top tube (no gel)

Minimum Volume

0.5 mL

Other Acceptable Specimens

Plasma collected in a NMR LipoTube (black/yellow-top) tube, or EDTA no gel (lavender-top) tube, or heparin no gel (green-top) tube

Instructions

Collect specimen in plain red-top tube, which is the preferred specimen. Hold tube upright at room temperature for 45 minutes and allow to clot. Centrifuge specimen after clotting according to manufacturer's specifications. Transfer to a transport tube for storage at 2°C to 8°C until shipped.

For NMR LipoTube (black-and-yellow-top tube), keep upright at room temperature for 30 minutes and allow to clot. Centrifuge at 1800 to 2200g for 10 to 15 minutes immediately after clotting. If the sample cannot be centrifuged immediately, it must be refrigerated at 2°C to 8°C and centrifuged within 24 hours of collection. The NMR tube should then be stored at 2°C to 8°C until shipped.

Separate plasma from lavender-top (EDTA-no gel) tube or green-top (heparin-no gel) tube immediately after collection and transfer to a plastic transport tube for shipment to the laboratory.

Do not open NMR LipoTube. Serum or plasma drawn in gel-barrier collection tubes other than the NMR LipoTube should not be used.

Clinical Significance

As an (1) aid in the identification and stratification of individuals at risk for future cardiovascular (CV) disease, (2) independent marker of prognosis for recurrent cardiovascular events in patients with stable coronary disease or acute coronary syndrome, (3) aid in the assessment of disease activity and risk of CV disease in adult Rheumatioid Arthritis (RA) and psoriasis patients, when used in conjunction with standard clinical assessment and for monitoring of anti-inflammatory treatment.
