Tests Catalogs

One 2.7 mL blue top (3.2% citrate plasma).

All blue top tubes collected for coagulation assays that do not have a blood culture collected first must have a discard tube collected prior to filling. The discard tube should be another blue top tube in which greater than 1 mL of blood is collected.

Minimum volume: 0.5 mL platelet poor plasma.

Clotted sample; hemolysed sample; tube fill volume less than 70% or greater than 110%; more than 4 hours since collection;  sample contaminated with I.V. fluid; sample not properly identified; incorrect container; insufficient sample volume.

Internal: Deliver to lab immediately at ambient temperature.
Offsite: Centrifuge within 30 minutes of collection, place at least 0.5 mL platelet poor plasma in an aliquot container and transport to the lab frozen.

Whole blood: Ambient, 4 hours.

Platelet poor plasma aliquot: Refrigerated, 4 hours; Frozen, (-20 degrees C), 2 weeks;  Frozen (-70 degrees C), 6 months.

Samples containing small amounts of residual heparin are pre-treated with hepzyme prior to testing. Hepzyme neutralizes up to 2 U/mL of heparin..
