5.0 mL Gold SST

2.0 mL EDTA Lavender tube

4.5 mL Green LIHEP PST tube

Collect FOUR 2.7 mL blue top tubes

Note: All Specimen must be collected

Blue top tubes must be filled within 10% of stated volume. A discard tube must be used if a citrate tube is to be drawn using a winged blood collection set. It is important to remove air from the blood collection set to ensure the proper blood volume is obtained in the coag tube.

If the patient has a known hematocrit >55%, please contact the coagulation lab for an adjusted collection tube before drawing the blood.

Run platelet count (EDTA) and send result. If not run, send EDTA tube at room temp less than 24 hours old (refrigerated up to 36 hours)

Double spin, separate, freeze plasma from coag (blue) tubes

Refrigerate red cells from a lavender EDTA tube in a seperate tube if platelet count is completed. If EDTA tube is unavailable, red cells from the sodium citrate (blue) tube may be used

Refrigerate SST tube for ACA

Green Lithium Heparin Tube: spin within one hour, refrigerate, no need to pour off plasma if gel barrier is present.
