Both membranous stain intensity and percentage of tumour cells stained are critical for CLDN18.2 reporting1
In addition to membranous stain intensity and percentage of tumour cells stained, it is recommended that the biomarker report also include:
Integrated reporting:
- The type of testing method used
- A description of the status of the sample, such as “positive,” “negative,” or “inconclusive”
- Any relevant notes or observations regarding the sample or results

Expert-recommended reporting template
Developed by the committee of experts, this template can help you generate reporting and integrate CLDN18.2 reporting into your current protocols.
Consistent, integrated reporting of biomarkers can inform clinical decision making and patient care2
Integrated biomarker reporting:
- Gives the HCP the ability to review biomarker test results that inform clinical approach
- Can be used as a tool to help pathologists educate the multidisciplinary team
