Phlebotomy Procedures and Specimen Handling Notes

Exam structure and assessment

  • First day of class summary: there are 33 quizzes, 11 midterm, 11 written final, and 11 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?
