Behind each sample is a patient

Our work is interdisciplinary. We combine our competences in cytomorphology, immunophenotyping, molecular genetics, chromosome analysis and FISH and thereby provide the ideal basis for an optimized, individualized, and highly reliable diagnosis. The responsibility for our patients is the center of our activities.


Examinations per sample in 2019

  • 1 cytomorphology
  • 2 immunophenotyping
  • 3 FISH
  • 4 molecular genetics
  • 5 chromosome analysis


Immunophenotyping is key to the diagnostics of hematologic neoplasia. It is used to complete diagnosis, classify diseases, assess prognoses and to quantify malignant cells over the course of treatment. Diagnostic application of the method is based on the characterization of antigen expression patterns among malignant cells and their discrimination from healthy cells.
