Validation of the Sysmex XT-2000iV hematology system for dogs, cats, and horses. I. Erythrocytes, platelets, and total leukocyte counts.
Abstract: The Sysmex XT-2000iV is a laser-based, flow cytometric hematology system that has been introduced for use in large and referral veterinary laboratories. Objective: The purpose of this study was to validate the Sysmex XT-2000iV for counting erythrocytes, reticulocytes, platelets, and total leukocytes in blood from ill dogs, cats, and horses. Methods: Blood samples from diseased animals (133 dogs, 65 cats, and 73 horses) were analyzed with the Sysmex XT-2000iV and the CELL-DYN 3500. Manual reticulocyte counts were done on an additional 98 canine and 14 feline samples and manual platelet counts were done on an additional 73 feline and 55 canine samples, and compared with automated Sysmex results. Results: Hemoglobin concentration, RBC counts, and total WBC counts on the Sysmex were highly correlated with those from the CELL-DYN (r>/=0.98). Systematic differences occurred for MCV and HCT. MCHC was poorly correlated in all species (r=0.33-0.67). The Sysmex impedance platelet count in dogs was highly correlated with both the impedance count from the CELL-DYN (r=0.99) and the optical platelet count from the Sysmex (r=0.98). The Sysmex optical platelet count included large platelets, such that in samples from cats, the results agreed better with manual platelet counts than with impedance platelet counts on the Sysmex. Canine reticulocyte counts on the Sysmex correlated well (r=0.90) with manual reticulocyte counts. Feline reticulocyte counts on the Sysmex correlated well with aggregate (r=0.86) but not punctate (r=0.50) reticulocyte counts. Conclusions: The Sysmex XT-2000iV performed as well as the CELL-DYN on blood samples from dogs, cats, and horses with a variety of hematologic abnormalities. In addition, the Sysmex detected large platelets and provided accurate reticulocyte counts.

The study examined the efficacy of the Sysmex XT-2000iV, a hematology system, in counting different types of blood cells in sick dogs, cats, and horses. The research found that Sysmex XT-2000iV was as effective as the current CELL-DYN 3500 system and also efficiently detected large platelets and counted reticulocytes accurately.
Objectives and Methodology
- The primary focus was to validate the utility and accuracy of the Sysmex XT-2000iV hematology system for veterinary purposes, specifically for counting erythrocytes, reticulocytes, platelets, and total leukocytes in the blood of ill dogs, cats, and horses.
- The study used blood samples from 133 dogs, 65 cats, and 73 horses, all of which were diseased. These samples were analyzed using both the Sysmex XT-2000iV and the currently used CELL-DYN 3500 systems for comparison.
- Manual reticulocyte and platelet counts were also conducted on additional feline and canine samples for further comparison with the automated Sysmex results.
Results
- The results showed a high correlation (r>/=0.98) between counts of hemoglobin concentration, RBC (Red Blood Cells), and total WBC (White Blood Cells) on the Sysmex system and the CELL-DYN system.
- However, systematic differences were observed for MCV (Mean Corpuscular Volume) and HCT (Hematocrit).
- MCHC (Mean Corpuscular Hemoglobin Concentration) correlation was lower in all species, ranging from 0.33-0.67.
- The Sysmex impedance platelet count in dogs showed a strong correlation with both the impedance count from the CELL-DYN (r=0.99) and Sysmex’s optical platelet count (r=0.98).
- The Sysmex system showed the ability to detect large platelets effectively. In cat samples, results aligned better with manual platelet counts than with impedance platelet counts on Sysmex.
- Reticulocyte counts using the Sysmex system for dogs and cats also showed a good correlation with manual counts.
Conclusion
- The study concluded that the Sysmex XT-2000iV system performs just as well as the CELL-DYN system on blood samples from dogs, cats, and horses with various hematologic abnormalities.
- In addition, the Sysmex system effectively detected large platelets and provided accurate counts of reticulocytes, a feature the traditional manuals counts or other systems might miss.
