- Acceptable: Serum from a centrifuged gold top serum separator tube.
|
| Minimum Volume/Size Required |
1mL serum |
| 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.

- 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 3 days of collection.
- Store serum frozen if testing will occur after 3 days of collection.
NOTE: * Gold top serum separator tube cannot be frozen. Serum must be transferred to a transport tube prior to freezing.
