One 6.0 mL red top tube, no gel, clot activator serum.
Patient Preparation
Do NOT use alcohol-based wipes to cleanse the patient's skin prior to venipuncture.
Pediatric Collection
Minimum volume: 1.0 mL serum.
Unacceptable Conditions
SST or PST gel tubes; specimens drawn in capillary tubes; insufficient sample volume; sample not properly identified; forensic samples.
Storage/Transport Temperature
Internal: Deliver to lab within one hour of collection. Offsite: Allow to clot for 30 minutes after collection. Centrifuge within one hour of collection. Place at least 1 mL serum in a tightly sealed aliquot container with minimal dead space and transport to lab at 2-8 degrees C (refrigerated or on ice).
Do not use alcohol prior to venipuncture. Specimen should be kept closed as much as possible. Specimen should be analyzed as soon as possible after collection. If prolonged storage is anticipated, the addition of fluoride (collected in a grey top tube) is recommended.
