Core Responsibilities

Primary Functions

Perform venipuncture on adult, geriatric, pediatric and neonatal patients using standard and specialized techniques (vacutainer, syringe, butterfly, capillary puncture), ensuring correct site selection, aseptic technique, and minimal patient discomfort.
Conduct capillary blood draws (fingerstick, heelstick) for point-of-care testing, neonatal screening, glucose monitoring and micro-collection tubes following facility policies and manufacturer instructions.
Verify patient identity using two patient identifiers (name, date of birth, MRN), confirm test orders, and explain procedures to patients to obtain informed consent and reduce anxiety prior to specimen collection.
Accurately label all specimens at the point of collection with patient identifiers, collection date/time, collector initials, test codes and any required special handling instructions to preserve chain-of-custody and ensure laboratory traceability.
Adhere to CLIA, OSHA, CDC and facility infection-control protocols by using appropriate PPE, sharps disposal procedures, and bloodborne pathogen precautions to maintain a safe work environment.
Prepare patients for blood draws by assessing venous access, applying tourniquets, warming sites when appropriate, and using vein-finding techniques or devices to increase first-stick success rates.
Collect specialized specimens such as blood cultures, timed collection samples (e.g., GTT, therapeutic drug monitoring), arterial blood gas (ABG) samples, and specimen types requiring special tubes or preservatives while following published guidelines for collection and transport.
Process specimens after collection by centrifugation, aliquoting, freezing, or preparing slides as required, and ensure proper storage temperatures and documentation for accurate downstream testing.
Operate and maintain phlebotomy equipment, centrifuges and point-of-care testing devices, perform routine quality checks and calibration, and report equipment malfunctions to supervisory staff promptly.
Document specimen collection events and patient interactions in the electronic health record (EHR) or laboratory information system (LIS), including collection times, labels, notes on difficult draws, and any specimen rejections or discrepancies.
Monitor specimen integrity by checking tubes for proper fill volume, correct anticoagulant usage, hemolysis, clots, and appropriate container closures; reject or recollect specimens per established criteria and document reasons.
Coordinate timely transport of specimens to the laboratory, blood bank or reference lab using proper biohazard packaging, temperature-controlled containers and courier systems to prevent delays that may compromise test results.
Assist with donor screening and phlebotomy for blood donation drives or mobile collection units by performing pre-donation tests, drawing whole blood or apheresis products and completing donor documentation and counseling as required.
Provide compassionate patient care to diverse populations, including patients with special needs, needle phobia, bleeding disorders or compromised venous access; modify approach to promote comfort while maintaining specimen quality.
Participate in venipuncture competency assessments, maintain active certification/licensure, and complete required continuing education to stay current on best practices and regulatory changes in phlebotomy and laboratory safety.
Implement and document quality control (QC) and quality assurance (QA) activities related to specimen collection, labeling accuracy, and adherence to SOPs; escalate recurring issues and participate in corrective action planning.
Respond appropriately to adverse events such as syncope, hematoma formation or inadvertent arterial puncture by following emergency protocols, providing first aid (including BLS/AED if certified), and documenting incidents per facility policy.
Train, mentor and provide on-the-job coaching for new phlebotomists, medical assistants or students on proper collection techniques, EHR documentation and safety procedures to build team competency and ensure consistent service.
Maintain inventory of phlebotomy supplies and reagents, perform stock rotation, place orders for tubes, needles, PPE and collection accessories, and coordinate with supply chain to prevent stock-outs that would disrupt operations.
Communicate proactively with nursing, laboratory and clinical staff to resolve test order discrepancies, address specimen rejection reasons and expedite critical or STAT collections to support timely patient care decisions.
Perform point-of-care testing (e.g., glucose, rapid antigen tests) according to manufacturer instructions and document results, including QC runs and instrument maintenance logs when applicable.
Ensure compliance with HIPAA by protecting patient privacy during collection, transport and documentation of specimens and by handling protected health information (PHI) securely.
Participate in performance improvement initiatives such as turnaround-time reduction, reduction of specimen rejection rates and patient satisfaction projects by providing frontline insights and implementing agreed changes.
Support research and clinical trial specimen collection protocols when needed by following study-specific procedures, labeling requirements and chain-of-custody documentation to meet regulatory trial standards.

Secondary Functions

Assist laboratory staff with accessioning, barcoding and routing of specimens to the appropriate testing departments when workload and staffing needs require cross-functionality.
Aid in maintaining a safe, clean and organized phlebotomy work area and mobile collection carts, including routine surface disinfection, waste segregation and compliance with biohazard disposal procedures.
Participate in departmental meetings, huddles and training sessions to share feedback on workflow improvements, patient care challenges and opportunities to enhance specimen quality.
Support outreach and community blood drives by setting up collection stations, educating donors about pre-donation requirements and ensuring regulatory documentation is completed.
Provide input for updating standard operating procedures (SOPs) and phlebotomy policies based on observed trends, new testing requirements or equipment changes.
Assist with administrative tasks such as scheduling patient draw times, managing appointment rescheduling due to weather or staffing constraints, and triaging incoming calls related to specimen collection.
Assist in the onboarding process by preparing training materials, competency checklists and shadowing schedules for new hires or rotating clinical staff.
Participate in inventory audits and help implement barcoding or tracking improvements to reduce stock discrepancies and expiration-related waste.
Support laboratory accreditation and inspection readiness by providing documentation and evidence of competency checks, QC logs and incident reports upon request.
