The percentages of carry-over inter samples is calculated with the following formula:
(Low value cycle 1) - (Low value cycle 3)
Carry-over =  × 100
(High value cycle 3) - (Low value cycle 3)
Accuracy:
Correlation was done with one commercial instrument (HORIBA ABX PENTRA 120 ®) and with about 100
normal blood samples (without alarm).
