Study Notes
Laboratory Specimen Handling
- Send specimens via pneumatic tube system, excluding CSF, deep wound cultures, blood bank bags/products, pathology specimens, and blood gases.
- Specimen requirements can be found in Careforce under Departments > Laboratory > Test Directory.
Patient Identification
- Use two patient identifiers: patient's name and Medical Record Number (MRN).
Blood Draw Protocol
- For drawing blood below an IV, the IV must be turned off for at least 2 minutes before collecting the specimen.
- For drawing blood above an IV, turn off the IV for at least 10 minutes prior to specimen collection.
Order of Blood Draw
- Follow the correct order of draw to avoid contamination:
- Blood cultures (pink, grey, purple)
- Blue
- Red
- Yellow
- Green
- Lavender
- Pink
- Grey (for lactic acid, must be on ice)
Test Considerations
- PTT (Partial Thromboplastin Time) can be falsely elevated if IV tubing is not adequately cleared before collecting the specimen.
Pediatric Considerations
- The amount of blood to inoculate in the PedsPlus aerobic culture bottle is up to 5mL.
- The minimum age for performing a fingerstick on a child is 1 year.
