In addition to developing the FENa test, his research is the scientific basis for the US Food Labeling Law, which stipulates that food labels must list the exact amount of sodium and other contents. Bilirubin is one of the breakdown product associated with hemoglobin in red blood cells. Deficiencies in the same conjugating machinery may also lead to jaundice in individuals with normal red blood cell turnover. Newborn hyperbilirubinemia assessment calculator is a tool for every pediatrician and concerned parent. Dr. Bhutanis primary research is focused on neonatal jaundice biology and management.
