Which phase features clay-colored stool due to bilirubin not reaching the stool?

• A. Preicteric
• B. Icteric
• C. Posticteric
• D. Convalescent

Answer: (B)

When bile cannot reach the intestine, stool loses its brown color because stercobilin, the pigment that gives stool its color, isn’t formed. This happens during the icteric phase, when bilirubin is elevated in the blood and bile flow into the gut is impaired, so stools become clay-colored. Urine may be dark from bilirubin excreted by the kidneys. In the preicteric phase there’s no jaundice yet, so stool color remains normal; in the posticteric phase jaundice fades and stool color typically returns to normal as bile flow resumes, with convalescence following as the body recovers.
