One 4.5 mL green top with gel (PST), (lithium heparin plasma).)Also acceptable: Gold top (SST); Red top, no gel.
Pediatric Collection
At least 0.5 mL blood in microtainer, green top with gel, plasma (lithium heparin).
Unacceptable Conditions
Frozen sample; sample not properly identified; insufficient sample volume.
Storage/Transport Temperature
Internal: Deliver to lab immediately at ambient temperature.
Offsite: Centrifuge within 2 hours of collection. For best accuracy, transport to lab at ambient temperature. Do not freeze (see Remarks).
Stability (from collection to initiation)
Ambient: 2 days
*Refrigerated/Frozen are not recommended
Remarks
Maintaining ambient temperature of the sample will provide the most accurate LD result. Freezing the sample will cause an immediate false decrease in LD value of approximately 10%. Refrigerated samples demonstrate a slow decrease of 10% after 24 hours.
