Identification of Jaundice in Newborns Using Smartphones
Neonatal jaundice is a common and most often harmless condition. However, when unrecognized it can be fatal or cause serious brain injury. Three quarters of these deaths are estimated to occur in the poorest regions of the world. The treatment of jaundice, phototherapy, is in most cases easy, low-cost and harmless. The crucial point in reducing the burden of disease is therefore to identify then children at risk. This results in the need for low-cost, reliable and easy-to-use diagnostic tools that can identify newborns with jaundice.
Based on previous research on the bio-optics of jaundiced newborn skin, a prototype of a smartphone application was developed and tested in a pilot study and the application refined.
This smartphone application will now be evaluated in a clinical trial set in two hospitals in Norway. The smartphone application gives immediate estimates of bilirubin values in newborns, and these estimates will be compared to the bilirubin levels measured in standard blood samples, as well as the results from ordinary transcutaneous measurement devices.

Detailed Description
The smartphone jaundice app system works by taking pictures of newborns with a custom-made color calibration card placed on their chest. This makes it possible to measure the skin color precisely regardless of the specific light source that is used to illuminate the newborn. The measured skin color is then compared with items in a database of simulated newborn skin colors. These simulated newborn skin colors have been created using numerical simulations of how light moves through skin, with varying skin parameters including, but not limited to, skin thickness, blood concentration, melanin, and of course bilirubin, the pigment that causes jaundice. By comparing the measured skin color with the simulated skin colors that are most similar to it, the investigators can then estimate the bilirubin concentration in the newborn's skin by e.g. averaging the bilirubin concentrations used to create these simulated skin colors.
In a group of 200 newborns with varying degree of jaundice, correlation between smartphone bilirubin estimates will be compared with total serum bilirubin and standard transcutaneous bilirubinometry.
