Samenvatting

This paper describes the use of automated microscopy to detect fetal erythroblasts in maternal blood. The technology is based on the following approach: (1) the use of centrifugal cytology for the preparation of monolayers; (2) simultaneous staining of fetal hemoglobin (immunoalkaline phosphatase) and chromosome sequences (FISH); (3) multi-mode microscopy to detect rare events; (4) visual evaluation of image memories containing detected objects. Model systems show that fetal cells in frequencies as low as 1 in a million cells can be detected easily (manually or by automated microscopy). Algorithms for automated cell selection were developed for a test set of 6 patients. Optimization of hardware and software routines will make analysis of several million cells in approximately 1 h feasible.
