3.5 mL
Minimum Volume
1.1 mL (Note: This volume does not allow for repeat testing.)
Container
Lavender-top (EDTA) tube or plasma preparation tube (PPT™)
Storage Instructions
Freeze (preferred) or refrigerate. Stable at room temperature for 24 hours or refrigerated for six days. Stable frozen for six weeks.
Causes for Rejection
Incorrect anticoagulant; PPT™ frozen and/or not centrifuged
