Biliverdin breaks down to bilirubin, which is yellow.
After the birth, your baby has a normal excess of red blood cells that break down into a substance called bilirubin, which she excretes in her bowel movements.

This includes a wide array of xenobiotics as well as endogenous substances, such as bilirubin, steroid hormones and thyroid hormones.
