Specimen Requirements
| Volume | Type | Container | Collect Temperature | Transport Temperature | Special Instructions |
|---|---|---|---|---|---|
| 2 mL | Fluid, body | EDTA (Lavender) | Refrigerated | Specify fluid type, collection date and time on requisition. For Peritoneal Specimens - Due to Processing differences, select Peritoneal Dialysis Fluid for all dialysate/CAPD fluid (instead of just Peritoneal). Samples must be refrigerated within 12 hours of collection to maintain specimen integrity. |
Alternate Specimen Requirements
| Volume | Type | Container | Collect Temperature | Transport Temperature | Special Instructions |
|---|---|---|---|---|---|
| 2 mL | Fluid, body | Sterile container | Refrigerated | Specify fluid type, collection date and time on requisition. For Peritoneal Specimens - Due to Processing differences, select Peritoneal Dialysis Fluid for all dialysate/CAPD fluid (instead of just Peritoneal). Samples must be refrigerated within 12 hours of collection to maintain specimen integrity. |

Special Info
Specify fluid type and collection date and time on requisition. Cell count and differential will be approximate if specimen is clotted. In rare circumstances, flow cytometry may be added on to evaluate substantial malignant cell populations.
Clinical Info
Evaluation of pleural or pericardial fluid. (For synovial or cerebrospinal fluid, see separate listings.)
