The laboratories listed below are categorized by the level or type of testing offered. The cost differs for each type of testing as does the amount of information provided.
Low-Cost Immunoassay Screen - These tests can be $50 or more and are commercially available for atrazine. They are qualitative and should not be relied on for actual concentration values but still give a more accurate result than an in-home test kit.
