The results of in vitro experiment. a The hematocrit of the rinse solution was stable over time (diluted 100 times). b HCT-M, the calculated blood loss was approximate to the Direct-M (2.0 ml) whatever the blood dilution ratio. c RBC-M, the calculated blood loss is close to the Direct-M only when the blood dilution ratio was greater than 300 times
