A new interlaboratory comparison (ILC) was organised in 2024 by the EURL in order to test the competency of participants regarding the detection by histo-cytopathology of the following pathogens : Bonamia sp., Marteilia sp., Perkinsus sp. and Mikrocytos sp.

The test included 30 scanned slides available under mScope:

- 10 scanned imprints (digestive gland or gills) of flat oysters Ostrea edulis.

- 10 scanned histological sections of flat oysters Ostrea edulis

- 10 scanned histological sections of cupped oysters Magallana gigas or Crassostrea virginica

The test was first opened to EU NRLs, it started in June 2024 and ended in October 2024. The result report was sent on the 24th of October.

The test is now open to laboratories outside of EU.
