Half and half nail

Half and half nails (also known as "Lindsay's nails") show the proximal portion of the nail white and the distal half red, pink, or brown, with a sharp line of demarcation between the two halves. Seventy percent of hemodialysis patients and 56% of renal transplant patients have at least one type of nail abnormality. Absence of lunula, splinter hemorrhage, and half and half nails were significantly more common in hemodialysis patients, while leukonychia was significantly more common in transplant patients.
