Microsatellite Instability testing (MSI) [Tissue]

Three mock clinical cases with human tumour tissue paraffin embedded (FFPE) samples and/or artificial FFPE (designed to simulate real patient samples). One 10um or 15um FFPE section per case is provided. Samples are provided as cut sections (rolled scrolls / curls) only – we cannot provide slide mounted materials.

Participants will receive an individual report including educational advice and a scheme report which includes additional information from the cohort of participants including geographical spread, methodologies employed, common errors, learning points and scheme statistics allowing participants to benchmark their results.

Each laboratory will also receive a single certificate listing all EQAs participated in with performance result for each year.

Participants are expected to test the samples according to their routine strategy. Where provided, the matched normal may be used as an optional aid to determine the MSI status of the tumour. 

For all cases, participants are expected to return a clinical report. Mandatory completion of an online data collection form is also required.  No restrictions on number of participants. Open to laboratories from ALL countries (note: some restrictions may apply due to sanctions, delivery network exceptions, restrictions on importation etc).
