Use of ice or cold packs is not recom-mended because of
possible cold activation of clotting factors and platelet disruption. ■ Acceptable time delays can vary depending on the specific coagulation test performed. Precentrifugation refers to specimen handling/processing after collection and prior to centrifugation. For specimens that do require Centrifugation refers to specimen handling/processing during centrifugation. It causes the specimen to rotate at high speeds, thereby Postcentrifugation refers to specimen handling/processing after centrifugation and prior to removal of serum or plasma. Serum or plasma should be physically separated from cells as soon as possible and no longer than 2 hours from the time of collection (unless there is conclusive evidence that longer times do not affect specific test
results.) Sets with similar termsHow should collected blood samples be stored after being sealed appropriately quizlet?(set at 37°C or 98.6°F. Care should be taken to keep the sample at 37°C or 98.6°F. Failure to keep the sample warm will result in erroneous laboratory results).
How do you prepare a blood specimen for transfer to public health quizlet?The preparation is done by transferring a portion of the specimen into one or more tubes that are labeled with the same information as the original specimen tube using a disposable transfer pipettes. Do not put specimen with different anticoagulants in the same aliquot tube and cover the tube.
What is the first thing you always do in specimen handling for safety?1. Always wear gloves and any other indicated barrier protection when collecting and handling laboratory specimens. 2. Place each laboratory specimen in an appropriate leak-proof primary container (e.g. vacutainer tube, specimen cup, etc.).
