The Immundiagnostik Experience

Your lab has many options when vetting and evaluating new assays. Here is what you can expect when working with us.

Your work is important, and we want to ensure you promptly get the answers you need. Our Technical Applications Team is highly experienced and prepared to answer your questions as quickly as possible. When more complicated issues arise, we can come on-site to help troubleshoot and find a solution.

Unlike other suppliers, we fully support our products because we manage the development and manufacturing processes from start to finish. We also maintain a robust inventory of products, allowing us to fulfill orders quickly and reliably.

While validating a new test in your lab is beneficial for expanding your offerings, we know these projects can be a huge undertaking. Our Technical Applications Team can provide in-person and remote validation support services to your lab, so you do not have to reallocate resources for these projects.

Being in business for over 30 years has allowed us to develop relationships with key scientific thought leaders around the globe. If there is ever a time when a solution to your lab’s challenges does not exist, we welcome opportunities to collaborate.
