External Transport Instructions

Samples can be transported frozen to the laboratory if the facilities are available to double spin and aliquot these sample. This has to be done within 4 hours.

Unspun sample is stable for up to 4 hours and must be transport to laboratory immediately. (Sample must be double spun, aliquoted and frozen within 4 hours from time of collection).

Processing Instructions

Transport sample to laboratory within 4 hours of collection.

The sample MUST be double spun and frozen within the 4 hour time limit.

Method

Centrifuge the two 3.5 mL citrate tubes and transfer the plasma to a labeled 4 mL plastic tube and re-centrifuge at room temperature (do not use the refrigerated centrifuge).

The double centrifuged plasma is transferred to two 1 mL eppendorf tubes and freeze.

Sample must be centrifuged within 4 hours of collection.

**Sample must be centrifuged within 4 hours of collection**

Centrifuge the two 3.5 mL citrate tubes (and transfer the plasma to a labeled 4 mL plastic tube and re-centrifuge at room temperature (do not use the refrigerated centrifuge).  One sample is acceptable but 2 samples are preferable for Lupus testing.

The double centrifuged plasma is transferred into a new labelled tubes. 

Double spun samples are then frozen in the -20'C freezer.
