Fecal immunochemical test (FIT)

Fully automated fecal occult blood analyzer


OC-SENSOR PLEDIA is the high-end fecal immunochemical test analyzer. Maximum 200 tests can be performed at one time and the sampling throughput is 320 tests per an hour. The operation is simple as just pressing “start” is required for analyzing.

High throughput-sampling

Advanced usability

Complete automation system

Squeeze-up system

The filtered sample goes into the sample cup part when squeezed by the instrument, then sampled into the reaction cuvette.

Only filtered sample solution is dispensed for analysis.


  • - Reduce carry-over
  • - Minimize analyzer maintenance
  • - Help achieve high reproducibility
  • - No need to open the device caps or pour sample into cups

Eiken Quality Control Survey (EQCS)

EQCS is an originally developed external quality assessment service for OC-SENSOR users through our distributors. The service started in 1995 and currently more than 600 laboratories from 18 countries (except Japan) participate in the program every year. EQCS supports laboratories to assess their performance objectively by comparison of the testing results among participants.
