Phlebotomy Procedures and Specimen Handling Notes
Exam structure and assessment
- First day of class summary: there are 3 quizzes, 1 midterm, 1 written final, and 1 tracking time (skill set).
- Tracking time involves the skills related to phlebotomy (e.g., in the arms, etc.), while the patient is still present.
Specimen labeling policy and rationale
- Specimens should be labeled after collection, but still in the presence of the patient (i.e., do not label ahead of time).
- Rationale for not pre-labeling: if the tube is wrong, labeling beforehand creates avoidable errors and misidentification.
- Do not label after the patient leaves the presence of staff, because that could cause confusion with another patient’s specimen.
- Labeling occurs after finishing collection, but while the patient is still present.
Patient identification and field considerations
- Patients have medical bracelets, which provide identification and identity verification.
- In the field, you should honor these identifiers and the patient’s wishes; identity verification is important and should be respected.
- The transcript emphasizes respecting patient wishes and identification cues (e.g., bracelets) during the procedure.
Handoff to the laboratory and chain of custody
- After collection, the phlebotomist hands the specimen to the laboratory driver who will transport it from the Patient Service Center to the lab.
- The driver must sign a sheet confirming receipt of the specimen (example wording from the transcript: "I received this urine").
- This establishes an initial chain-of-custody record from collection to transport.
Laboratory processing and sign-off
- In the laboratory, the specimen is received by a staff member (a lab tech/technician).
- The lab tech signs off the receipt of the specimen.
- There is a subsequent sign-off by Medical Technology (MT) or a similar department confirmation, indicating that the specimen has been logged into the system and is ready for processing.
Color-coding and identifying tube contents
- The transcript raises the question of how to determine color information for specimens (e.g., urine tubes or other tubes).
- The answer given in the transcript points to a trainer or supervisor who will provide color-coding details (e.g., "Laurie is going to tell you").
- Practical takeaway: confirm tube color conventions with the supervising staff member during training to ensure correct identification of specimen type and ordering of tests.
Concepts, implications, and best practices
- Always label specimens in the presence of the patient to minimize mislabeling risk.
- Do not pre-label or post-label after the patient has left to avoid cross-patient contamination or confusion.
- Respect patient identification cues (e.g., medical bracelets) and patient preferences during collection, handling, and labeling.
- Maintain a clear chain of custody: collection → transport by lab driver (signature) → receipt in lab (sign-offs by tech) → MT sign-off.
- Understand that color-coding and specimen type identification are often taught by a supervisor; verify color conventions with the designated trainer (e.g., Laurie) during training.
- The process supports accuracy, traceability, and patient safety in specimen handling.
Practical scenarios and examples from the transcript
- Scenario: You complete collection, then label the specimen while the patient is still present, using the bracelet for identity verification.
- Scenario: After collection, you hand the specimen to the lab driver who signs the pickup sheet to confirm transfer.
- Scenario: In the lab, the specimen is received by a technician who signs off, followed by an MT sign-off to finalize the intake.
- Question to study: How is color information for tubes communicated? Answer: by instruction from the supervisor/trainer (e.g., Laurie) during training.
Quick reference checklist (study aid)
- [ ] Confirm patient identity with bracelets and verbal confirmation before collection.
- [ ] Collect blood and label only after collection, while the patient is still present.
- [ ] Do not label ahead of time to prevent mislabeling.
- [ ] Do not label after the patient leaves; ensure labeling occurs during presence.
- [ ] Hand off specimen to lab driver with signed pickup sheet.
- [ ] Lab staff sign off on receipt; MT/Medical Technology also signs off.
- [ ] Confirm tube color conventions with supervisor/trainer (e.g., Laurie).
- [ ] Reflect on ethical/practical implications: patient autonomy, accuracy, and chain-of-custody.
Possible exam-style prompts (from the content)
- Explain why specimen labeling should occur in the presence of the patient and not before collection.
- Describe the chain-of-custody steps from collection to MT sign-off.
- How should patient bracelets influence labeling and identification during a phlebotomy procedure?
- Who provides the color-coding information for tubes, and why is this important for accurate processing?
