Pathology Services

Board-certified pathologists providing custom solutions to support all areas of clinical research and diagnostic development
Our team can develop special stains for IHC across all major platforms and interrogate large cohorts of samples using custom high-density tissue microarrays (TMA). Tumor assessments can be performed in conjunction with our Multiplex Immunofluorescence services, and microdissection can be performed for RNAseq or NanoString applications 
Our global lab network combined with our kitting and logistics ensure rapid turnaround of results and stable transit of tissue samples to accelerate your development timelines.
  • Precision’s on-site pathologists offer a breadth of customized solutions

    Our on-site pathologists are solely dedicated to research, providing complete quality control and in-depth analyses of your samples. Supporting all areas of clinical research – biomarker discovery and evaluation, companion diagnostics development, and in vitro diagnostics (IVD) development, including clinical trial work, regulatory support, and optimizations.

Digital pathology

Precision for Medicine offers digital pathology solutions to enable simpler storage, sharing, and retrieval of whole slide images (WSIs)—for real-time collaboration across laboratories.

We invested in multiple on-site scanners to ensure our solutions are platform agnostic, and on boarded the necessary technologies, such as HALO AP and Proscia Concentriq®, to develop a seamless workflow for delivery, storage, and analysis of your samples.

Scanning platforms

These platforms also allow for flexibility in sample review and collaboration, while accelerating your sample procurement timelines. 

  • Use of software-based image analysis for better and faster quantification of WSIs using solutions like HALO from Indica Lab or Visiopharm
  • Development and training of complex AI algorithms for tumor and/or cell classification
  • Real-time collaboration with other pathologists with online collaboration and image management tools like Concentriq for Research and HALO AP
  • Z-stacking capabilities for difficult to scan slide types, like Tissue Microarrays (TMAs)
