Bedside tests for psoriasis
Two bedside tests can be done to confirm the clinical diagnosis of
psoriasis : -
i. Grattage test
Scraping the lesion with a glass slide causes accentuation of the
silvery scales.
ii. Auspitz's Sign
Scraping the lesion with glass slide causes accentuation os slivery
scales (as in Grattage test). If scraping is continued further, a
glistening white adherent membrane (Burlkey's membrane) appears.
On removing Burlkey's membrane punctate (fine pin point) bleeding
become visible, which is referred to as Auspitz's sign.
