Navigating Challenges with PD-L1 Combined Positive Score (CPS)
 
This activity is designed to help pathologists and laboratory professionals learn how PD-L1 testing, and interpretation is performed using the combined positive score (CPS). Panelists will review how CPS is used to determine PD-L1 positivity. They will also describe some of the challenges associated with scoring certain types of cancers using CPS. Panelists will list some practical ways to ensure optimal PD-L1 testing and scoring using CPS.  
Provided by the American Society for Clinical Pathology in partnership with Q Synthesis LLC.
 
The activity offers 0.5 CME/CMLE credit.
 
Target Audience
This activity has been designed to meet the educational needs of pathologists and laboratory professionals diagnosing cancer.
