Tests in development
Tests for research use only body fluid mononuclear %&#, body fluid polymorphonuclear %&#, early granulated cells %&#, high light scatter reticulocytes %&#, low hemoglobin density, microcytic anemia factor, mean sphered cell volume, plateletcrit, platelet distribution width, reticulocyte distribution width (RDWR and RDWR-SD), red cell size factor, unghosted red cells %&#, leukocyte estimates (UWROP, WDOP, WNOP, WROP), cell population data research parameters
Tests unique to analyzer
Differential method(s) used flow cytometric digital analysis using volume, conductivity, and five angles of light scatter, digital signal processing, advanced algorithm applications, high-definition cellular resolution, DataFusion
• WBC count/RBC count 0.050–400.000/0.005–8.500
• Hemoglobin/platelet 0.10–25.50/3.0–3000.0
• MCV (fL) or Hct (%) 0.00–85.00 (Hct) for operating range, 50.00–150.00 (MCV) for measuring range
• WBC count/RBC count ≤3.0%/≤1.5%
• Hemoglobin/platelet ≤1.5%/ ≤3.5%
• MCV or Hct ≤1.0% (MCV)
Accuracy of automated differential compared with manual differential (per CLSI H-20A2) neut= ±2.0; lymph, mono= ±3.0; eso, baso= ±1.0 (or 10%, whichever is greater)
Interfering substances:
• WBC precipitated elevated proteins, cryoglobulin, fragmented white cells, agglutinated white cells, lyse-resistant red cells, giant platelets, platelet clumps, unlysed particles >35 fL in size
• RBC very high WBC count, high concentration of very large platelets, autoagglutinins
• MCV or Hct very high WBC count, high concentration of very large platelets, autoagglutinins
• Platelet platelet clumps, white cell fragments, very small red cells, red cell fragments, giant platelets, electric noise
• Hemoglobin severe lipemia, heparin, certain unusual RBC abnormalities that resist lysing
Interfering substances: Differential elevated triglycerides, precipitated elevated proteins
