Patient's question:
Age of female baby: 3 and a half monthsMedical history: Yellow complexion observed two days after birth; laboratory tests showed elevated jaundice indicators. At two and a half months, a skin test was conducted, with three values showing two around 4 points something and one around 3 points something. The doctor said it was mostly normal, only slightly elevated, but couldn't specify the exact normal range.
Doctor's answer:
Generally, the data measured through the skin should be less than 10 (the values may vary slightly depending on the instrument); if blood is drawn to measure the level of bilirubin in the blood, the normal value is usually less than 205 umol/L (12 mg/dL). For a normal infant at 30 days, the total bilirubin normal range is 1.7 to 17.1 umol/L (0.1 to 1.0 mg/dL). Direct bilirubin is 0 to 6.8 umol/L (0 to 0.4 mg/dL). Indirect bilirubin is 1.7 to 10.2 umol/L (0.1 to 0.6 mg/dL). Blood tests are required to determine the true level of bilirubin, as the measurement through the skin can be affected by the child's skin color and fat thickness.
