IDEXX ProCyte Dx® Hematology Analyzer

  • Three cutting-edge technologies working together
    Laser flow cytometry, optical fluorescence and Laminar Flow Impedance™ work together to give you unprecedented accuracy, speed and precision.
  • Two-minute run time
    Real-time answers during your patients’ visits let you share results and recommendations with clients face-to-face, while simple operation minimizes time and effort.
  • More complete medical information
    Get a more complete picture of each patient’s health with an advanced five-part white blood cell differential, absolute reticulocyte count, and band neutrophil and nucleated red blood cell (nRBC) parameters. In addition, the ProCyte Dx® analyzer provides the ability to run body fluid analysis and validated results on 26 different blood parameters.*


The ProCyte Dx analyzer connects to the IDEXX VetLab® Station Laboratory Information Management System to provide:

  • All your diagnostic information in one comprehensive patient report
  • Access to IDEXX SmartService™ Solutions: remote troubleshooting for your IDEXX VetLab® analyzers that saves time and helps keep your laboratory running smoothly

Real-time results at the push of a button


The ProCyte Dx® analyzer takes work out of your hands and lets you get back to your patients and clients more quickly.

  • Load-and-go operation: Even maintenance is push-button for increased staff productivity.
  • Small sample size: The analyzer requires only 30 µL of anticoagulated blood. And veterinary-specific IDEXX VetCollect® EDTA tubes require only 0.5–1.5 mL of blood to get the most accurate results for every patient.
  • More species: Results are validated for nine species (canine, feline , equine, bovine, ferret, rabbit, gerbil, pig and mini pig) across 26 different parameters.* Simple, intuitive flagging highlights questionable results, like clumped platelets or abnormal white blood cell patterns, to indicate the need for further investigation, including a blood film review.
  • 30-second return: Sample tube is returned in 30 seconds and available for further testing.
  • Fluid sample analysis: Now running a body-fluid cell analysis, which can assist in fluid classification, is as easy as running whole blood. Simply queue up the patient, load the sample and press go.


Dot plots

Dot plots are a visual representation of the complete blood count (CBC); each dot represents a single cell. Dot plots are a critical element of the CBC, providing a snapshot of cellular morphology. Only the ProCyte Dx Hematology Analyzer and the LaserCyte® Dx Hematology Analyzer provide these valuable tools.


Smarter technology for better hematology


The ProCyte Dx® analyzer employs three cutting-edge technologies to provide the most comprehensive complete blood count (CBC) available in-house.

Laser flow cytometry delivers an advanced five-part white blood cell differential. The ProCyte Dx® Hematology Analyzer uses laser flow cytometry to perform a full analysis of multiple characteristics of each white blood cell, for the most accurate interpretation of all five white blood cell types.
Optical fluorescence provides a highly sensitive and accurate reticulocyte count with the use of specific fluorescent stains. Feline platelets are analyzed with this method to ensure superior separation when delineating platelets and red blood cells of similar size.
Laminar Flow Impedance™ performs the fastest and most precise count of red blood cells for quick and accurate analysis. With advanced Laminar Flow Impedance technology, cells are lined up one by one to ensure each cell is characterized individually.

The process involves staining sample cells, directing laser light of 633 nm at each cell and collecting multiple angles of light scatter. Wavelengths of 660 nm and greater—denoted here in blue—are captured for very precise measurements of the cell’s nucleic content. Only the ProCyte Dx analyzer offers this superior capability for highly sensitive and accurate analysis.



Accuracy defined


You need hematology results you can trust, and the ProCyte Dx analyzer delivers. The analyzer’s performance has been documented in four peer-reviewed abstracts published by the American College of Veterinary Internal Medicine (ACVIM). Previous to the abstracts’ publication, we spent 24 months at four leading veterinary schools, partnering with internationally recognized experts in veterinary hematology and running over 80,000 samples in multiple field trials.

A recent study comparing the ProCyte Dx analyzer to the Advia® 120 showed unparalleled red blood cell count, hematocrit, platelet count and white blood cell count correlation, as shown here.1

ProCyte Dx® Hematology Analyzer Test Menu


The ProCyte Dx Hematology Analyzer offers a full menu of hematology parameters and prints all your IDEXX VetLab® in-house analyzer results in one comprehensive report. The report provides a complete picture of your patient's health status and facilitates face-to-face communication with clients.

Results are validated for nine species (canine, feline, equine, bovine, ferret, rabbit, gerbil, pig and mini pig) across 26 different parameters.* Simple, intuitive flagging highlights questionable results, like clumped platelets or abnormal white blood cell patterns, to indicate the need for further investigation. Other species capabilities are available.


HCT (hematocrit)With every report
RBC (red blood cell count)
  • A vital supplement to the HCT
  • Accurate measurements allow accurate calculations of MCH and MCHC.
HGB (hemoglobin)With every report
RETIC , %RETIC (reticulocyte count, percentage of reticulocytes)Reticulocytes are essential and the gold standard for characterizing if an anemia is regenerative or nonregenerative.
MCV (mean cell volume)Serial measurement allows better monitoring of the progression/regression of a disease state.
RDW (red blood cell distribution width)
  • Objective measurement of variation in size of red blood cells (anisocytosis)
  • Allows the veterinarian to better follow the progression and regression of a disease
MCHC (mean cell hemoglobin concentration)With every report
MCH (mean cell hemoglobin)With every report
PLT (platelet count)The ProCyte Dx analyzer offers a much more accurate platelet count than impedance-only counters
MPV, PDW, PCT (mean platelet volume, platelet distribution width, platelet hematocrit)Aid in the characterization of a platelet abnormality (such as presence or absence of a bone marrow response to a peripheral demand for platelets)
WBC (white blood cell count)With every report
Monocytes and Lymphocytes (% and #)
  • Help identify inflammatory diseases where macrophages are a significant component of the inflammatory process
  • Differentiation of monocytes and lymphocytes helps accurately identify the presence of an underlying glucocorticoid influences (e.g., stress, steroid administration, hyperadrenalcorticism)
Neutrophils (% and #)Important in identifying certain types of inflammatory disease and their severity, as well as following the progression or regression of inflammation
Band NeutrophilsNoted when bands are suspected to be present in a sample. The presence of bands is the single best indicator of inflammation.
Eosinophils (% and #)
  • Important in identifying systemic hypersensitivity, which can be caused by heartworm disease, flea bite dermatitis, feline asthma, allergic gastroenteritis and more
  • The ProCyte Dx analyzer identifies eosinophils for both canines and felines
Basophils (% and #)May be helpful in identifying systemic hypersensitivity, as well as acute allergic reactions
nRBCs (nucleated red blood cells)Noted when nRBCs are suspected to be present in a sample. nRBCs indicate bone marrow damage or extreme increases in red blood cell production, both of which prompt the doctor to act quickly.
Fluid AnalysisThe ability to run body-fluid analyses for real-time cell counts and assistance in fluid classification
TNCC (total nucleated cell count)A count of all nucleated cells in a body fluid, including white blood cells, nucleated red blood cells and both benign and malignant somatic cells, such as mesothelial cells, epithelial cells, etc.
Granulocyte (# and %)Nucleated cells including all three granulocyte populations: neutrophils, eosinophils and basophils
Agranulocyte (# and %)Nucleated cells including all nucleated cells not included in the “granulocyte” category: lymphocytes, monocytes, macrophages, mesothelial cells, neoplastic cells, etc.
RBC (red blood cell count)A count of all non-nucleated red blood cell forms
