Instructions
Overnight Fasting is suggested. Avoid hemolysis.
1. 2 Red top tubes should be collected and placed in a prewarmed thermos (37º C) containing sand immediately after collection.
2. Samples should be brought back to the lab where they are placed in a 37º C waterbath for 1 hour to allow the tubes to clot.
3. After the 1 hour incubation period the tubes need to be centrifuged in a pre-warmed centrifuge for 10 mins at 5000 rpm.
(If no heated centrifuge is available, allow centrifuge to cycle 1 round to warm it up then proceed to spin tubes down.)
4. Remove serum into 2 pour off tubes and send into Sandridge Reference Lab.
5. Cryoglobulin, if present, will be lost in the clot if processed below 37º C.
6. Ship at room temperature. Do not refrigerate or freeze.
