A complete blood count (CBC) is the most wide-spread laboratory test. The WBC differential count is a part of the CBC procedure. Despite high automation of laboratory tests, the WBC differential count is still performed manually. This part of the CBC requires particular attention, focus and highly qualified technologists.

Vision Hema Ultimate automates the differentiation of leucocytes and erythrocytes in blood smear. Load the slides into the cassette, insert it into the analyzer and the system will automatically perform white blood cell differentiation and morphological analysis of red blood cells. Final results will be presented in the form of cell images pre-classified into groups. The specialist only has to validate the results on a PC.

Manual method

Comparison of automatic and manual blood smear analysis methods. Vision Hema Ultimate analyzes up to 700 blood smear samples in 24 hours. According to regulatory standards, manual WBC differential count of 1 smear takes 6 minutes. In other words, only 240 samples can be analyzed within the same time frame compared with the automatic method.




Efficient use of time increases laboratory productivity and saves resources

Vision Hema Ultimate is 4.5 times more efficient than the manual method
Up to 4.5x

Automatic method

Vision Hema Ultimate Automatic method

Vision Hema Ultimate automatically scans and analyzes blood smears. The specialist works with images of cells pre-classified into groups on PC monitor. Validation of 1 sample takes only 1 minute, which means the specialist examines 350 samples per shift. As a result, analysis of 700 blood smear samples only requires 1 workplace and 2 specialists that work in shifts.

Manual method

Manual method

A specialist manually examines approximately 80 samples per shift. The analysis is fully manual. Examination of 700 blood smear samples would require 3 workplaces and 9 specialists operating on a three-shift basis.

Control and validity of results

Quality control

Vision Hema Ultimate performs blood smear analysis as defined by "Reference Leukocyte Differential Count (Proportional) and Evaluation of Instrumental Methods. CLSI H20-A2".

Each examined sample stores information about leucocyte’s collection path, detection control and quality control for differentiation of each type of leucocyte.

The system automatically calculates diagnostic sensitivity, specificity and efficiency for each type of leucocyte to evaluate quality control.

Quality control values are used for evaluation of leucocyte pre-classification accuracy. Diagnostic sensitivity (DSn), specificity (DSp) and efficiency (DE) are calculated as follows:

DSn = TP / (TP + FN)
Dsp = TN / (TN + FP)
DE = (TP + TN) / (TP + TN + FP + FN), where

TP — true positive, TN — true negative, FP — false positive, FN — false negative.

If the cell does not change its type (cell type 1) after validation, the result of its identification is considered true-positive (TP). If the cell does not change its type to cell type 1 after validation by the specialist, the result of its identification is considered true negative (TN).

If the cell is identified as cell type 1 but then changes its type, the result of its initial identification is considered false positive (FP). If the cell type is changed to cell type 1, the result of its identification is considered false negative (FN).
