  • Self-calibrating bilirubin test card system and method
    Patent number: 11547994
    Abstract: A sample of blood is placed on a bilirubin test strip and plasma separated from the red blood cells. The bilirubin test strip is located on a test card along with a set of calibration images, the colors of the calibration images being associated with known plasma bilirubin levels. A photograph is taken of the test card. The bilirubin level of the blood sample is determined by, within the photograph, interpolating the color of the plasma and the colors of the closest colored calibration images.
