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 LaserCyte® Dx Hematology Analyzer and the ProCyte Dx® Hematology Analyzer provide these valuable tools.

Laser Flow Cytometry

The LaserCyte® Dx Hematology Analyzer uses reference laboratory technology to analyze blood samples. The analyzer focuses a laser beam on each individual cell and quantifies the scatter of light on four separate detectors.

Simultaneously, the analyzer measures the amount of time it takes a cell to travel through the laser beam. This cell travel time is referred to as the “time of flight” and it provides data on the diameter of the cell.

Think of a flashlight as an analogy for the laser. Passing a golf ball in front of the light is quicker than passing a basketball through the same light.

While the time of flight, or cellular diameter, is being measured, four other detectors are measuring the quantity of light bouncing off the ball.

The dimpled design of a golf ball will refract light differently than the seamed design of a basketball. Therefore, in this analogy, the golf ball would be classified as a different “cell” from the basketball.

The four detectors quantify the scatter of light from each cell to measure size, complexity, granularity and light absorption—the same qualities a pathologist would examine when looking at a blood film.

Laser Flow Cytometry Diagram

The LaserCyte Dx Hematology Analyzer provides the data needed for a more complete diagnosis because it can:

  • Analyze red blood cells
  • Identify the reticulocytes and generate an absolute reticulocyte count
  • Identify all five types of white blood cells

Advantages of laser flow cytometry

  • Because a laser flow cytometry-based analyzer evaluates multiple characteristics (nuclear and cytoplasmic material) of red blood cells, white blood cells and platelets, it produces more accurate and reliable counts than other systems.
  • Clumped platelets can be detected and flagged.
  • Large platelets (frequently encountered in cats) can be distinguished from erythrocytes due to difference in the scatter of light caused by the platelet granules.
  • Laser flow cytometry-based analyzers are able to rapidly count large numbers (>200,000) of erythrocytes, which are needed to produce accurate and repeatable reticulocyte counts.



Accuracy verified


To ensure the trusted hematology results you need, we partnered with Purdue University, the University of Florida, Tufts University and Michigan State University to compare the performance of the LaserCyte Dx Hematology Analyzer to the ProCyte Dx® Hematology Analyzer.

The following graphs compare the results obtained using two LaserCyte Dx analyzers and a ProCyte Dx analyzer at the University of Florida. The data includes canine, feline and equine samples (totaling 100 of each species split across the two LaserCyte Dx analyzers). These results indicate good correlation between the LaserCyte Dx and the ProCyte Dx for canine, feline and equine samples.1

LaserCyte® Dx Hematology Analyzer Parameters

The LaserCyte® 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 five species (canine, feline, equine, pig and ferret) across 24 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 review of the blood film. Other species capabilities are available.
