The influence of Romanowsky-Giemsa type stains on nuclear and cytoplasmic features of cytological specimens.

The aim of the present study was to compare the staining pattern of the standard azure B-eosin Y stain with commercial May-Grünwald-Giemsa (MGG) stains on cytological specimens by means of high resolution image analysis. Several cytological specimens (blood smears, abdominal serous effusions, bronchial scrape material) were air dried, methanol fixed and stained with the standard azure B-eosin Y stain and with commercial May-Grünwald-Giemsa stains. Integrated optical density (IOD) and colour intensities of cell nuclei and cytoplasm were measured with the IBAS 2000 image analyser. Commercial MGG stains gave much higher coefficients of variation for all parameters than the standard stain. Reproducibility of cell nuclei segmentation versus cytoplasm was significantly better for the standard stain. Contamination of the standard stain with methylene blue partly copied the staining pattern of commercial stains. The standard azure B-eosin Y stain is recommended for high resolution image analysis (HRIA) of cytological samples.
