Impression cytology with transfer: an easy method for detection of vitamin A deficiency.
We described a new method to stain epithelial cells harvested by ocular impression. The cells are immediately transferred on a glass slide after the sampling; this transfer permits a very simple staining and easier reading by light microscopy. The results are compared with those obtained with the previous techniques and confirm ocular impression as a good help for vitamin A status determination.
