||The quantitation of lipids in human serum is used to determine the risk of coronary heart disease.
|Supplemental Information Required
|Performed on Specimens from (sources)
|Sample/Specimen Type for Testing
- Preferred: Serum from a red top tube transferred to a transport tube
- Acceptable: Serum from a centrifuged gold top serum separator tube.
|Minimum Volume/Size Required
|Storage/Preservation Prior to Shipping
- Collect blood in red top or gold top tube.
- Gently invert the tube with the blood specimen five times immediately after collection.
- Allow to clot 30 minutes from collection.
Centrifuge gold top tube to separate serum from red blood cells.
- For red top tube: Immediately transfer serum into a transport tube.
- For gold top tube: Immediately transfer serum into a transport tube if serum will be frozen.*
- Store serum cold if testing will occur within 7 days of collection.
- Store serum frozen if testing will occur after 7 days of collection.
NOTE: * Gold top serum separator tube cannot be frozen. Serum must be transferred to a transport tube prior to freezing.
- Two patient-specific identifiers required (e.g., patient full name, date of birth, Medical record number)
- Identifiers on specimen must exactly match submission form.
|Shipping and Specimen Handling Requirements
