Cytological and Biomolecular Measuring Procedures

Working Group 8.32

Profile

Analytical methods used in medical laboratories are crucial for decision making in many areas of medical diagnosis and treatment. We offer metrology support for laboratory medicine particularly for cell counting. This includes development of reference measurement procedures, and supply of measurement capabilities for the measurement quantities of the complete blood count, i.e. determination of reference measurement values for the concentration of erythrocytes, leukocytes and platelets, as well the haemoglobin concentration and related measurands.

For this purpose we develop flow cytometers with traceable volume dosage. In addition, our devices allow to measure the concentration of nanoparticles, with potential application to viruses or even fragments of DNA. Microscopic cell counting, e.g. using counting chambers, is used for comparison, particularly if identification of biological particles or sample density measurement poses particular challenges.
