Step By Step Approach to Examining Nails

    • L – Look across the nail bed from the side of each finger.
    • E – Estimate the interphalangeal depth at the level of the distal interphalangeal joint and nail bed.
    • A – Assess the nail-bed (hyponychial) angle.
    • P – Place the nails of corresponding (ring) fingers back to back and look for Schamroth’s window sign.
    • O – Observe for fluctuant movement of the nail on the nail bed using thumbs and index fingers.
    • N – Note if the interphalangeal depth ratio is >1, the nail fold angle is >190 degrees, and Schamroth’s window sign is absent.
