Method and apparatus for preparing a cellular container comprising means for pre-analysis of a sample that has been taken

A method for preparing a cell suspension for analysis, comprising at least the following successive steps:

• (a) taking a first portion of a sample of the cell suspension using a pipettor, said pipettor comprising at least one pipe;
• and
• (b) pre-analyzing the entire first portion of the sample that has been taken by a pre-analysis analyzer placed on the pipe of the pipettor, said pre-analyzing comprising measuring the cell density of the first portion of the sample that has been taken and comparing the measured cell density to a reference density,
• wherein,
• (i) if the measured cell density is lower than the reference density, the pre-analyzing further comprises taking a second portion of the sample of the cell suspension using the pipettor so that a combined volume of the first portion and the second portion in the pipettor has a volume of the cell suspension that is larger than a standard volume, or
• (ii) if the measured cell density is higher than the reference density, the pipettor is used to take a volume of the first portion of the sample of the cell suspension, wherein the volume is smaller than the standard volume, so as to obtain deposit smears with a homogenous density, and
• (c) depositing the sample present in the pipettor in an analysis container,
• wherein steps (a)-(c) are repeated to provide a number of deposited smears of homogenous density for analysis.
