Leonard Apt (original) (raw)

Leonard Apt (June 28, 1922 – February 1, 2013) was an American pediatrician and ophthalmologist. He was one of the first U.S. physicians to complete a fellowship in pediatric ophthalmology. Apt identified that povidone-iodine could be safety used as an antimicrobial for the eyes. In addition to his work in ophthalmology, Apt devised a number of diagnostic tests. The Apt test is performed on blood in a baby's stools to determine whether it is of maternal or fetal origin.
