Patient Identification and Consent

1Step-by-Step Procedure

1. 1

   Before entering, review the requisition for the patient's full name, date of birth, and test(s) ordered.

2. 2

   Knock and enter, greet the patient, and introduce yourself by name and role.

3. 3

   Ask the patient to state (not confirm) their full name and date of birth — never ask "Are you John Smith?" since patients may answer yes out of confusion or politeness.

4. 4

   Compare the patient's stated identifiers against the requisition and, if present, their wristband.

5. 5

   If any identifier doesn't match, stop and resolve the discrepancy with nursing staff before proceeding — do not draw the sample.

6. 6

   Explain what you're about to do in plain language and ask for verbal consent.

7. 7

   If the patient declines or hesitates, acknowledge their right to refuse and notify the ordering clinician or nurse rather than proceeding.

8. 8

   Proceed with the collection only after identity is confirmed and consent is given.

What Your Instructor/Preceptor Is Checking

• ✓

  Uses two independent identifiers (full name and date of birth), asked as open questions, not yes/no confirmations.

• ✓

  Cross-checks identifiers against both the requisition and the patient's wristband when one is present.

• ✓

  Stops and escalates rather than drawing when identifiers don't match.

• ✓

  Clearly explains the procedure and obtains verbal consent before beginning.

• ✓

  Responds appropriately — notifying the care team, not arguing — if the patient refuses.

Common Mistakes

• ⚠

  Asking "Are you Mr. Smith?" instead of "Can you tell me your full name?" — a yes/no question doesn't verify identity.

• ⚠

  Relying on a room number or bed assignment alone to identify a patient.

• ⚠

  Proceeding with a draw despite a mismatch between the wristband and requisition, assuming it's a clerical error.

• ⚠

  Skipping consent because the order "says to draw it" — consent and the physician's order are two separate requirements.

• ⚠

  Arguing with or pressuring a patient who refuses, rather than notifying the nurse or ordering provider.

Practice Tips

• →

  This is one of the few procedures where a single error (wrong-patient draw) can cause real harm — treat identification as non-negotiable, every time, with no exceptions for "I already know this patient."

• →

  If anything about the identifiers feels inconsistent, it costs almost nothing to double-check and a great deal to get wrong.
