1. Blood smears made from EDTA specimens must be prepared within 3 hours of collection to preserve the integrity of the blood cells. 2. A specimen collected and placed in an evacuated tube with a gel barrier may prevent blood glycolysis for up to 24 hours. 3. Specimens that require separation of the serum or plasma from the cells should be centrifuged within 1 hour of arrival in the lab.

1. Blood smears made from EDTA specimens must be prepared within 3 hours of collection to preserve the integrity of the blood cells.
2. A specimen collected and placed in an evacuated tube with a gel barrier may prevent blood glycolysis for up to 24 hours.
3. Specimens that require separation of the serum or plasma from the cells should be centrifuged within 1 hour of arrival in the lab.
4. Serum specimens can be centrifuged right away as opposed to plasma specimens that needs standing for at least 30 minutes before allowed to be centrifuged,
5. Removal of the cap/stopper of the evacuated tube before centrifugation allows loss of carbon dioxide and a decrease in the blood specimen pH.
