摘要
A sample acquiring device (10) for volumetric enumeration of white blood cells in a blood sample comprises a measurement cavity (20) for receiving a blood sample. The measurement cavity (20) has a predetermined fixed thickness. The sample acquiring device further comprises a reagent (22), which is arranged in a dried form on a surface defining the measurement cavity (20). The reagent (22) comprises a hemolysing agent for lysing red blood cells in the blood sample, and a staining agent for selectively staining white blood cells in the blood sample. A system comprises the sample acquiring device (10) and a measurement apparatus. The measurement apparatus comprises a sample acquiring device holder, a light source, and an imaging system for acquiring a digital image of a magnification of the sample. The measurement apparatus further comprises an image analyser arranged to analyse the acquired digital image for determining the number of white blood cells in the blood sample.
