Interlaboratory study for effect-based in vitro methods to detect estrogenic activity

2022-04-08

Stonehenge

This is the first study within QuoData’s recent proficiency testing program for effect-based in vitro methods. Interested laboratories will have the opportunity to participate in further interlaboratory studies of QuoData’s EQA program for biotests in the future.

The interlab study at a glance

This study is designed as an interlaboratory comparison exercise to provide information on comparability and reproducibility of the in vitro methods used and goes beyond the scope of a classical proficiency test. This interlaboratory comparison approach is therefore interesting for accredited and non-accredited laboratories.

Within this study the following kind of samples will be analyzed:

  • An aqueous extract from a food or personal care product

  • A surface water sample spiked with a strong estrogenic compound to gain a EEQ of approx. 10 to 50 ng/L.
