Blood withdrawal from central venous access devices, or CVADs, for laboratory studies is a common practice in home health. Patients generally prefer blood withdrawal from CVADs over venipuncture to avoid the brief pain and discomfort associated with venipuncture. Risks of this procedure include bloodstream infection (BSI) due to catheter manipulation at the hub, loss of catheter patency (occlusion), and erroneous laboratory values. Attention to Aseptic Non Touch Technique, or ANTT, and adequacy of flushing and locking will reduce risks of infection/occlusion.

In this training, we’ll review the equipment and procedures for CVAD blood sampling for laboratory studies. This course includes

- Video demonstrations of procedures
- Downloadable procedure guide PDFs
- Tips and best practices for performing these procedures in the home

This course was reviewed by Danielle Pierotti, RN, PhD, CENP, to ensure the content meets current professional guidelines and best evidence-based practices.
