Research Matters

Because IHControls® and IHCalibrators™ are leading-edge technology, they have been the subject of extensive research, much of which is supported by the National Cancer Institute.  Many of the findings were published in prestigious journals in the fields of laboratory medicinehistology and histopathology.

Collaborative Studies

Collaborate With Us

As evidenced by the collaborations in our publications, abstracts, posters, and collaborative studies, we value external collaborations that are ultimately aimed at delivering better patient care. If you see an opportunity to improve biomedical testing where we might be able to help, please contact us.

We have a high interest in collaborations leading to IHC assay standardization. Now that IHC laboratories can measure analytic sensitivity (lower limit of detection) by using IHCalibrators™, there is an important pending question for many, possibly most, IHC tests: To identify the analytic sensitivity that best correlates with diagnostically accurate test results. In other words, for IHC tests, what lower limit of detection yields the best fit-for-purpose result? We are looking for surgical pathology collaborators interested in developing data-driven guidelines.
