Our Team

AnaPath is recognized for the scientific competence in toxicologic pathology, high operational speed and reliability. The field of experience is surprisingly wide for a young company due to our history. Therefore we have the strength to support development of pharmaceuticals, chemicals, agrochemicals, medical devices just to name a few areas. Furthermore, our work combines not only the core business of toxicological pathology but also neuropathology, inhalation pathology, bone marrow evaluations, immunological processes, pathology in unusual laboratory species (fish, amphibian, birds, and invertebrates), hard material techniques immunohistochemistry/TCR, foetal pathology and image analysis. Our clients benefit from the scientific excellence of our team in the areas of anatomy, toxicologic pathology, biomedical engineering, genetics or regulatory toxicology regardless if they need support in pathology re-evaluation of an unexpected finding or design a complex pre-clinical safety assessment package.
