Welcome to EPTIS
We help you find a Proficiency Testing (PT) scheme or round for your laboratory.

PT scheme database

The EPTIS PT scheme database is our core service, brought to you by a network of coordinators worldwide.

There are many PT schemes operated worldwide. You find a large share of them in our database - 1000s of them are regularly operated, and some are on demand. Try it out: the database is free and easy to use. Examples for your database query:

sars virus
color colour textile
radioact* environm*

Found a suitable PT scheme? Please contact its provider directly for further info.
