Specimen Requirements
| Container Type: |
Optimal: Gold or Mint* *For STAT requests |
|
Acceptable: Red or Green |
|
| Optimal Collection Volume: |
4.5 mL; full tube |
| Specimen Minimum Volume: |
|
| Collection Instructions: |
Gently invert sample 5-6 times after collection. |
| Specimen Transport: |
Refrigerate |
| Processing Instructions: |
1. If serum, allow the sample to clot for 30 minutes. 2. Centrifuge specimen within 2 hours of collection. 3. After centrifugation, specimen tubes without a gel barrier should have the serum or plasma aliquoted to a false bottom container. 4. Keep serum/plasma refrigerated until testing can be performed. |
Specimen Stability
| Specimen Type | Temperature | Time |
|---|---|---|
| Serum* | Refrigerated | 3 days |
| Room Temperature | 8 hours |
*Note: Heparinized plasma in gel separator tubes is less stable than serum and is only suitable for add-on testing up to 2 days following sample collection.
Specimen Rejection Criteria
