Summary
DescriptionKB stain, annotated.jpg
English: KB stain, which may be subjective for borderline cells, but in this case shows cells counted as fetal cells with green check mark. The cells by a red cross at top are too incompletely colored to be counted as fetal cells, and the cell at right is too small to be counted.
