ABSTRACT:
A lytic reagent composition is provided which selectively stromatolyses red blood cells in a blood sample. In addition, a lytic reagent system is provided which enables the differentiation of at least three subpopulations of leukocytes. A method for using the lytic reagent system is also provided. Still further, the lytic reagent system finds use in the determination of the hemoglobin in the blood. The lytic reagent system utilizes an alkyl sulfate, polyoxyethylene based surfactant and acid with a hypertonic, alkaline, stabilizing reagent. The system and analysis method maintains the cellular morphology of the leukocytes and can be used to analyze normal and abnormal blood samples, fresh and aged blood, human and non-human animal blood samples.
