What do phlebotomist do as core job functions
At its foundation, what do phlebotomist do centers on five core responsibilities every hiring manager expects you to know and demonstrate:
Blood collection techniques (venipuncture and finger sticks)
Performing safe venipuncture and fingerstick collections is the most visible part of the role. Interviewers will expect you to describe your technique, comfort level with needles, and steps taken to reduce patient discomfort. Sources outline venipuncture and capillary collection as primary tasks for phlebotomists BetterTeam, Indeed.
Patient identification and verification
Accurate patient ID checks and verbal confirmation prevent specimen mix-ups. Emphasize your approach to matching IDs, confirming full names and birthdates, and cross-checking requisition forms — an essential element of what do phlebotomist do in any clinical workflow Indeed.
Specimen labeling and preparation
Proper labeling, aliquoting, and preparing specimens for transport preserve sample integrity. Discuss how you double-check labels, apply barcodes if used, and package samples following lab protocols to avoid rejection or re-draws BetterTeam.
Safety and sterilization protocols
Infection control, sharps disposal, and equipment sterilization protect patients and staff. Demonstrate knowledge of universal precautions, hand hygiene, and local safety policies when explaining what do phlebotomist do to reduce workplace risks Oroville Hospital Job Description (PDF).
Record-keeping and administrative tasks
Charting, updating electronic records, and managing specimens are part of daily workflow. Employers expect detail-oriented candidates who can maintain accurate logs, manage supply inventories, and help with patient intake tasks BetterTeam, Indeed.
Use brief, specific examples from your experience to show you can execute these functions reliably. Quantify when possible — e.g., "I complete routine draws in under 10 minutes and maintain a <1% specimen rejection rate."
What do phlebotomist do to ensure patient identification and specimen integrity
When interviewers ask about accuracy, they’re testing how you prevent errors. Explain step-by-step how what do phlebotomist do includes verification and chain-of-custody practices:
Verify patient identity using two identifiers (name + DOB) and match requisitions.
Confirm tests ordered and collection timing (fasting vs. postprandial).
Label tubes immediately at bedside; never pre-label before identifying the patient.
Record collection time, collector initials, and any special handling (e.g., on ice).
Communicate clearly with lab staff if a sample appears hemolyzed or compromised.
Telling a short story of a time you caught a mislabeled tube or prevented a mistaken draw demonstrates situational awareness and attention to detail — two traits central to what do phlebotomist do.
What do phlebotomist do to maintain safety sterilization and infection control
