Instructions

Adult: Minimum 2.5 mL 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. Specimens are stable on or off the clot, red blood cells, or separator gel for up to 24 hours at room temperature or up to 6 days at 2 to 8°C. If testing will be delayed more than 24 hours for specimens stored at room temperature or more than 6 days for specimens stored at 2 to 8°C, remove serum or plasma from the clot, red blood cells, or separator gel and store at -20°C or colder. Stored specimens must be inspected for particulates. If present, mix and centrifuge the specimen to remove particulates prior to testing. Avoid more than 3 freeze/thaw cycles. Specimens must be mixed THOROUGHLY after thawing, by LOW speed vortexing or by gently inverting, and centrifuged prior to use to remove red blood cells or particulate matter to ensure consistency in the results. To ensure consistency in results, specimens must be transferred to a centrifuge tube and centrifuged at > 10,000 RCF (Relative Centrifugal Force) for 10 minutes before testing if they are initially reactive and require retesting in duplicate.
