This study was undertaken for the purpose of observing the reaction for indican in the urine of the new-born under physiologic conditions
Momidlowski1 tested for indican in the urine of three healthy infants between the ages of 10 and 12 days. He obtained intense reactions which on the second and third day following were negative or showed only traces.
