Instructions

Adult minimum 2.5mL blood *Pediatric* minimum 2 full microtainers

Transport Temperature

Lab Only: It is recommended that tubes of blood are to be kept closed at all times and in a vertical position. It is required that the serum or plasma be physically separated from contact with cells within two hours from the time of collection. Analyze fresh specimens, if possible. Separated specimens are stable for 24 hours at room temperature, and at 2 to 8°C for up 7 days. If testing will be delayed more than 24 hours, remove plasma or serum from the red blood cells, clot or separator gel. Specimens removed from the red blood cells, clot or separator gel may be stored at 2 to 8°C for up to 7 days and frozen at <= -10°C for 6 months. Stored specimens must be inspected for particulates. If present, mix and centrifuge the specimen to remove particulates prior to testing. Avoid multiple freeze/thaw cycles. Specimens must be mixed THOROUGHLY after thawing, by LOW speedvortexing or by gently inverting, and centrifuged prior to use to remove red blood cells or particulate matter to ensure consistency in the results.
