Preferred Specimen
2 mL serum collected in a red-top tube (no gel)
Patient Preparation
Patient should be fasting 12 hours
Minimum Volume
1 mL
Instructions
1. Gently invert draw tube 5X (DO NOT SHAKE).
2. Let blood clot for 30-60 minutes at room temperature.
3. Centrifuge for 10 minutes.
4. Aliquot top layer from red-top draw tube and place SERUM in transport tube and dispose of draw tube. Label the transport tube as "No Additive Serum Red". ONLY ship No Additive Serum in transport tube.
5. Store and transport refrigerated. Specimen is stable at -20° for 10 days and -70° for 28 days but CANNOT BE SHIPPED ON DRY ICE.
Note: Adults without other risk factors for heart disease should receive a lipid panel once every five years. Individuals who have had an abnormal lipid panel, or those who have other cardiovascular risk factors, may be tested more frequently.
