Coverage

Every test species, one schema.

Whether the test organism is a fathead minnow or a sea-urchin embryo, the data model stays the same. CETIS holds every endpoint — survival, growth, fertilization, germination — in one queryable structure.

A look inside

Data entry to finished report.

Four steps your analysts run every day, each shown on a real CETIS screen.

In their words

Trusted across labs, agencies, and universities.

“The versatility of the CETIS software is unparalleled in its ability to manage all of our statistical evaluations supporting WET testing, dredge sediment evaluations and ecological risk assessments.”
KS Ken Simon Technical Director, EnviroSystems, Inc.
“The CETIS software is a critical element of our laboratory data management system… it has dramatically improved our efficiency, and the flexible statistical tools support our full scope of services for our clients.”
Stephan Clark Vice President, Pacific EcoRisk, Inc.
“CETIS has simplified WET data management at every step… sharing test data with permittees, permit writers, or labs is straightforward. I could not do my job nearly as well without it.”
Randall Marshall WET Coordinator, WA Dept of Ecology
“CETIS is a complete toxicity testing database. It sets up the tests, creates the paperwork, analyzes the data, prepares the reports… I can't imagine anyone doing toxicity testing without CETIS.”
Stan Asato Supervisor, EMD Toxicity Testing Unit, City of L.A.
