The Cito CBC system is a quantitative automated hematology analyzer intended for in-vitro diagnostic use to determine the following parameters with whole blood anticoagulated with K2EDTA (Venous): - CBC parameters: white blood cell count (WBC), red blood cell count (RBC), platelet count (PLT), hemoglobin concentration (HGB), hematocrit (HCT), and mean corpuscular volume (MCV); - 5-Part WBC Differential (WBC Diff): neutrophil count and percentage (NEUT and NEUT%), lymphocyte count and percentage (LYMPH and LYMPH%), monocyte count and percentage (MONO and MONO%), eosinophil count and percentage (EO and EO%), basophil count and percentage (BASO and BASO%). It is not indicated for use in diagnosing or monitoring of oncology patients, critically ill patients, or children under the age of 2 years.

The Cito CBC system is an automated hematology analyzer that is intended to analyze human whole blood, and report results of 16 hematology parameters. The system consists of a tabletop analyzer, the Cito CBC Analyzer, and a disposable test cartridge, the Cito CBC Cartridge. The analyzer includes software with Graphic User Interface to guide users to complete test procedure. To perform a test, the test cartridges and other test consumables are provided as a test kit. The current version of the test cartridge is designed for testing whole blood anticoagulated with K2EDTA. The current version of the test kit is designed for testing venous whole blood collected in a vacutainer tube. The Cito CBC analyzer utilizes the principle of fluorescent flow cytometry for cell count and cell classification. A laser is used as the light source, and fluorescence and light scattering signals are detected for the measurements. For fluorescent labeling, blood cells are treated with a fluorescent dye that has high affinity binding to nucleic acid. Additionally, the analyzer utilizes the principle of two-wavelength photometry for the measurement of hemoglobin. Blood cells are lysed to release hemoglobin. Meanwhile, the light scattering signal measured from the flow cytometry and the light absorption signals measured from the photometry are both used to quantify the hematocrit and the mean corpuscular volume. The Cito CBC cartridge is self-contained with all reagents to perform a test. The blood sample is applied to the test cartridge, and the test cartridge is inserted into the analyzer to complete the test. The analyzer has a pneumatic module which provides pressure to the cartridge and drives the applied sample to mix with reagents to form multiple sample mixtures. The cartridge has transparent flow cells to support the measurements of sample mixtures by fluorescent flow cytometry and photometry. The sample mixtures and the measurement wastes are all self-contained inside the cartridge for safe disposal after the test.
