Collection Instructions
| Specimen: | Fluid |
| Optimal Volume: | 0.3 mL |
| Minimum\Peds Volume: | 0.3 mL |
| Container: | Plastic leakproof container, sterile |
Processing and Shipping
| Specimen Processing: | Do not process. Send sample and request form to the Acute Care Laboratory for processing. |
| Shipping Instructions: | Ship at refrigerated temperature. |
| Stability: | Give sample to Chemistry for special handling.
Chemistry: Centrifuge, remove supernatant for CEA and fluid amylase and dilute as appropriate. Leave button in collection container and add back 0.5 mL sterile saline. Order a NGNCT and send button in saline with request form to Cytology. Cytology Laboratory: Create cytospin slides for low volume specimens. Always prepare a slide for pap stain and a second slide for Histology for Mucicarmine stain. Room temperature - 8 hours; refrigerated - 48 hours; frozen - indefinitely. |

Interpretive
| Reference Range: | By report. The ADVIA Centaur CEA and Vista 1500 Amylase methods are used. Results obtained with different assay methods or kits cannot be used interchangeably. |
| Use: | Malignant lesions can shed cells into a fluid in close proximity of the tumor. Isolating diagnostic cells from their supernatant aids in the detection or extent of a disease. Using the supernatant from a pancreatic cyst specimen preserves the supernatant, so it can be used at a later date for analysis of tumor markers, viscosity and enzymes. |
