Expanding Access to Testing: Updated Interim Guidance on Prioritization for COVID-19 Laboratory Testing

This Guidance is no longer in effect and is for historical purposes only.

​Testing for Coronavirus Disease 2019 (COVID-19), both PCR and serology, is becoming more readily available at hospital, academic, commercial, and public health laboratories across California. Governor Newsom and the Testing Task Force are committed to rapidly expanding testing across California, ensuring that more Californians get tested. Expanded testing will help protect vulnerable groups and allow us to better understand the spread of COVID-19 in our communities. 

This interim guidance is intended to support public health officials, health care providers, and laboratories in determining prioritization of specific groups for PCR molecular testing. The guidance will be reassessed on a weekly basis based on California's evolving situation and input from stakeholders. The prioritization categories below are suggested as guidance to sequential expansion of testing. As testing capacity increases, testing should expand accordingly at the discretion of the Local Health Officer.

All persons should stay home and away from others until there has been no fever without the use of fever-reducing medications, there has been improvement in respiratory symptoms (e.g., cough, shortness of breath) for at least 3 days; AND it is at least 7 days since symptoms first appeared, i.e., the minimum length of time will be 7 days.
