Jaundice appearing in the first 24 hours of life is considered which?

• A. Pathologic
• B. Abnormal
• C. Physiologic
• D. Not concerning

Answer: (B)

Jaundice that appears in the first 24 hours of life signals pathologic jaundice. This timing matters because physiologic jaundice—due to the newborn’s immature liver—typically starts after the first day and peaks a few days later. When jaundice is present within the first 24 hours, it usually indicates an underlying problem such as hemolysis from blood group incompatibility, infection, polycythemia, or a metabolic disorder, and it requires prompt evaluation and potential treatment to prevent bilirubin-related complications. The term abnormal is not the standard label used in this context; the key distinction is early onset being pathologic, not simply "abnormal" or not concerning.
