Abstract: A method for detecting characteristic cells in a sample includes performing a first lysis of a sample to yield a first lysate wherein nuclei of the cells of the sample remain intact. Freely available RNA in the first lysate is extracted and classified to ascertain the amounts of various types of RNA in the first lysate. A second lysis operation on the previously lysed sample is performed to yield a second lysate wherein the cell nuclei of the cells in the sample are destroyed. DNA freely available in the second lysate is extracted and a total cell count of cells in the provided sample is calculated on the basis of the amount of extracted DNA. The number of cells having individual cell markers in the provided sample is calculated using the ascertained amounts of various types of RNA and the calculated total cell count.
