!Collection Info<br />
!Interferences/Rejection Criteria<br />
|-<br />
|EDTA (lavender top)<br />
|<br />
* CBC, differential, blood morphology<br />
|<br />
* Transport within 1h<br />
* Run within 24h<br />
|<br />
|-<br />
|Sodium citrate (light blue top)<br />
|<br />
* Coagulation<br />
* Citrated platelet count (if EDTA-induced platelet clumping occurs)<br />
** WBC and PLT count (multiply by x1.1 to correct for dilution)<br />
** MPV reported<br />
** Depending on site, other parameters can also be reported from citrated tube (x1.1)<br />
|<br />
* Run within 4h<br />
* Spin to separate plasma and freeze long term<br />
* 9:1 fill ratio<br />
|<br />
* Improper fill (over- or under-filled)<br />
** Overfill -> clumping (not enough anticoagulant)<br />
** Underfill -> prolonged coag results (too much anticoagulant)<br />
* Improper mixing<br />
* High hematocrit (requires adjusted hematocrit)<br />
* Clotted<br />
* Gross hemolysis<br />

|<br />
|<br />
|}<br />
Adjusted citrate for hematocrit<br />
<br />
* Adjust whenever ≥0.55<br />
* C= (1.85 x 10^3) (100-HCT) (V)<br />
** C = volume of sodium citrate that should remain<br />
** HCT = hematocrit<br />
** V = blood volume (e.g., 2.7 mL sodium citrate tube)</div>
