Yet in Japan, the practice is still viewed with something of a jaundiced eye by the upper classes as a practice fit only for the lower classes, street walkers and gangsters.
Jaundice comes from the French word jaune, which means yellow; thus a jaundiced baby is one whose skin color appears yellow due to bilirubin.
Thus, if an infant begins to appear jaundiced, bilirubin levels will be ordered to determine the severity.
The test may be repeated frequently in a jaundiced newborn to assure that bilirubin levels are dropping.
Erythroblastosis fetalis overwhelms the removal system, and high levels of bilirubin accumulate, causing hyperbilirubinemia, a condition in which the baby becomes jaundiced.
