Laboratory Notes

Cryoglobulin (Serum) and cryofibrinogen (EDTA) must be collected using a “hot box”.

Once the hot box has arrived in the lab, check the serum has clotted, then the serum (and EDTA) can be centrifuged.

(NOTE: if the serum has not clotted, put the samples in the incubator while waiting for it to clot)

Do not spin in a cool centrifuge.

After the serum and EDTA are centrifuged, separate the serum and plasma immediately. These aliquots must be kept at room temperature all the way to the Heidelberg laboratory.
