Histopathology Individual Animal Lesion Data (IAD)

DOI: https://doi.org/10.22427/NTP-DATA-022-00002-0028-000-6

This data collection contains individual animal lesion data collected by the Division of Translational Toxicology (DTT). This data has been curated from multiple legacy and modern sources. Findings deemed "Within Normal Limits" or samples identified as "Not Examined" have been excluded from this dataset. Additional data will be added to this dataset as it becomes available.  Tissue name, locator, morphology, modifier, and severity terminologies have been standardized for this dataset using the DTT Data Dictionary that has been reviewed by NIH pathologists.  

Test compounds, species, strains, routes, units, and treatment roles have been standardized to the DTT Data Dictionary.​

These datasets are being reviewed by subject matter experts and are offered here as preliminary drafts. Final versions may differ depending on reviewer comments.

Simple dose-response studies can be identified by the Dose Response Study Flag field.
