GLP Histology & Preclinical Pathology Services

At iHisto, we specialize in providing GLP Histology and GLP Preclinical services designed to support pharmaceutical, biotech, and academic research organizations. Our GLP-compliant workflows ensure accuracy, reproducibility, and regulatory alignment, enabling you to accelerate preclinical studies with confidence.

​

Whether you are conducting toxicology, pharmacology, oncology, or safety assessment studies, iHisto delivers the highest quality histology and pathology support, helping your team generate robust preclinical data packages that meet FDA and sponsor audit expectations.

Why GLP Histology and GLP Preclinical Services Matter

In drug development, preclinical histology plays a pivotal role in evaluating the safety, efficacy, and tissue-level impact of investigational compounds. Regulatory agencies, including the FDA, require toxicology and pathology data from studies performed under Good Laboratory Practice (GLP) conditions.

​

By combining deep histology expertise with GLP standards, iHisto ensures that every tissue section, stain, and analysis is performed with full traceability and audit-readiness. This enables your data to stand up to regulatory review and support decision-making for IND submissions and beyond.

Our GLP Histology Capabilities

Our GLP Histology and Preclinical workflows support a wide range of research programs:

​

  • Safety & Toxicology Pathology – acute, sub-chronic, chronic studies; liver, kidney, immune, cardiac, and bone marrow toxicities

  • Carcinogenicity & Genotoxicity – tumor classification, genetically modified models, proliferation/apoptosis markers

  • Pharmacodynamics – oncology and fibrosis models, biomarker evaluation by IHC/IF/ISH

  • Medical Device Pathology – GLP histology evaluation of tissue response and biocompatibility

  • Biologics & Small Molecules – biomarker expression, mechanism-of-action studies

  • Reproductive Pathology – ovary, testis, uterus, placenta; GLP reproductive toxicology support

  • Wound Healing Models – fibrosis, angiogenesis, inflammatory biomarkers

  • Inhalation Toxicology – lung histology, surfactant proteins, inflammatory responses

  • Neurologic Models – CNS histology, demyelination, GFAP/NeuN/Iba1 staining

  • Digital Pathology & Peer Review – whole-slide imaging (GLP compliant), remote access, pathology peer review

​

By integrating these applications into a GLP framework, we provide clients with high-quality preclinical pathology datasets that support regulatory submissions and sponsor decision-making.
