Final answer:
Rising reticulocyte count in a newborn can lead to significant jaundice, a condition caused by high levels of bilirubin in the blood.

Rising reticulocyte count in a newborn is associated with a complication known as significant jaundice. Jaundice occurs when there is an excess of bilirubin in the blood, causing the skin and eyes to appear yellow. In newborns, high levels of bilirubin can lead to neurological damage, so it is important to monitor and treat significant jaundice promptly to prevent complications.
