If the jaundice etiology is unknown after the initial laboratory evaluation, it is necessary to perform additional tests including hepatitis panels and autoimmune panels, such as antinuclear, smooth muscle, and liver-kidney microsomal antibodies.3, Noninvasive imaging modalities in persons with jaundice include ultrasonography, computed tomography, and magnetic resonance cholangiopancreatography. When your liver processes the bilirubin, it unbinds it from the albumin and binds it to a sugar molecule, making it water-soluble.
