ABSTRACT:
A stable calibrator composition, useful in equipment for determining hematological values in blood samples, comprises a hemolysate of red blood cells which have been lysed with a dilute aqueous solution of saponin to which has been added a halophenol that has a phenol coefficient of between 20 and 90 to provide a concentration from about 1:1000 to about 1:1750 w/v of said halophenol in said hemolysate, said calibrator composition having a pH between 4 and 7. The preferred halophenol is 4-chloro-3,5-xylenol.
