Transport specimen at Room Temperature to lab
Specimens for vWF multimer analysis assays kept at room temperature, should be centrifuged and tested within 4 hours of time of collection.
If testing is not complete within 4 hours, plasma should be removed from the cells (2 X 1 mL Eppendorf tubes) and frozen at -20 C for up to 2 weeks or -70 C for up to 6 months.
A frost-free freezer should not be used. |
