Hematology Services 

To assist in the identification of potential toxicities associated with agents, Charles River offers multiparameter diagnostic hematology analysis. Because our analyzer uses specialized veterinary software for multi-angle scatter separation (MAPPSTM) technology, we provide more accurate results than labs using cell staining or instruments calibrated to human blood parameters.

Some of the measurable hematological parameters include:

  • White blood cell counts
  • Neutrophil, lymphocyte, eosinophil and basophil absolute counts and percentages
  • Hemoglobin and hematocrit analysis
  • Platelet counts


Hematological analysis can be performed on samples as small as 0.25 mL. Uses for this data include:

  • Screening for lead identification
  • Identification of bone marrow and other hematological toxicities
  • Comparison and screening of related compounds
  • Determination of hematological recovery times
  • Examination of alternate dosing schedules
  • Analysis of chemoprotectant activities
  • Planning for future toxicology studies


All analyses are calibrated and performed to rigorous quality control standards.
