Process for Detecting Nucleus-Containing Cells in a Sample Liquid of a Patient using a Microfluidic Device and Microfluidic Device

A process for detecting nucleus-containing cells in a sample liquid of a patient using a microfluidic device, comprising:

• mixing the sample liquid with a lysis buffer in a mixing chamber of the microfluidic device to obtain a lysate;
• applying the lysate onto a carrier substrate of the microfluidic device to obtain a cell sediment and cell suspension of the lysate;
• and
• identifying the nucleus-containing cells from the cell sediment.

A microfluidic device for detecting nucleus-containing cells in a sample liquid of a patient, wherein the microfluidic device is formed as a lab-on-chip cartridge, and wherein the microfluidic device comprises:

• a mixing chamber configured to receive the sample liquid and a lysis buffer in order to obtain a lysate;
• a carrier substrate configured to apply the lysate, in order to obtain a cell sediment and cell suspension of the lysate;
• and
• a detection chamber, wherein the carrier substrate is arranged and/or is configured to be arranged in the detection chamber.
