Can CNA draw blood?

Typically, a Certified Nursing Assistant cannot draw blood based solely on their core certification. The standard CNA curriculum and state competency examination do not include training or assessment in phlebotomy skills. Therefore, performing this procedure is generally outside a CNA's authorized scope of practice. However, the definitive answer to whether a CNA can draw blood depends on state-specific regulations and the acquisition of an additional credential.

Understanding the limitations and possibilities is crucial for exam preparation and legal practice.

  • Standard Prohibition: The baseline CNA role focuses on activities of daily living and basic clinical tasks. Consequently, invasive procedures like venipuncture are excluded. State boards deliberately omit phlebotomy from the certification exam to enforce this boundary.
  • Pathways to Authorization: Some states allow CNAs to perform phlebotomy if they obtain a separate certification. This requires completing a state-approved phlebotomy training program and passing a corresponding skills evaluation. In these cases, the CNA works under an expanded scope.
  • Employer-Specific Policies: Certain healthcare facilities, particularly long-term care centers, may institute internal training programs. These programs allow CNAs to perform capillary blood glucose tests (fingersticks) after demonstrating competency, but rarely include venipuncture.

In summary, while a standard CNA certification does not permit you to draw blood, it can serve as a foundation for pursuing the necessary phlebotomy credentials. The answer to can a CNA draw blood is ultimately determined by state law and supplemental certification, not the core CNA examination. Always verify your state's Board of Nursing regulations before performing any advanced procedure.
