Final answer:
Jaundice can be diagnosed by examining the skin for yellow discoloration.
Step-by-step explanation:
The skin is an easy place to examine for the yellow discoloration seen with icterus, also known as jaundice. Jaundice occurs when there is an accumulation of bilirubin, a bile pigment, in the blood. When the concentration of bilirubin reaches a certain level, it diffuses into peripheral tissues and gives them a yellow color. Examining the skin for this yellow discoloration can help diagnose jaundice.
