Committee advances AB 481 to let CLIA‑qualified personnel assist in labs under supervision; unions seek training standards and ratios

Assemblymember Rubio told the committee AB 481 would allow federally qualified Clinical Laboratory Improvement Amendments (CLIA) personnel to assist licensed laboratory staff with specific tasks under direct, on‑site supervision by licensed personnel. The bill’s sponsors said the measure is intended to mitigate an acute shortage of clinical laboratory scientists in California and speed test turnaround for patients.

Industry witnesses including the California Clinical Laboratory Association and large diagnostic providers said the bill clarifies permissible assistance in laboratories (non‑patient facing tasks such as specimen handling, equipment cleaning and moving assays between instruments) while maintaining licensed personnel physically present and responsible for supervision. Supporters argued that expanding supervised assistance will allow licensed staff to focus on work that requires their licensure and reduce testing delays.

Labor unions — including engineers and scientists and SEIU — registered opposition unless amended. Their concerns included the lack of a required minimum certification (for example, phlebotomy or other standardized training) for assisting personnel and absence of a supervision ratio in the bill; unions said employer‑provided training alone creates non‑standardized results and that specimen mishandling or mislabeling can cause false results with significant patient harm. Supporters said the bill now requires laboratory directors to designate supervisors and maintain training records; sponsors said they were negotiating additional clarifying amendments with stakeholders.

The committee voted to pass AB 481 to Appropriations with the item left on call pending absent members; sponsors and opponents said they would continue negotiations on ratios and training standards.
