Different labs may have slightly different ranges for what they consider normal bilirubin levels. On average, total bilirubin levels between 0.2 and 1.3 mg/dL are considered normal for children and adults.
Adult: >12 mg/dL. Newborn: >15 mg/dL. Next: Interpretation. Bilirubin is a tetrapyrrole and a breakdown product of heme catabolism. Most bilirubin (70%-90%) is derived from hemoglobin...
Typical results for a total bilirubin test are 1.2 milligrams per deciliter (mg/dL) for adults and usually 1 mg/dL for those under 18. Typical results for direct bilirubin are generally 0.3 mg/dL. These results may vary slightly from laboratory to laboratory. Results may be slightly different for women and children.
Normal Results. It is normal to have some bilirubin in the blood. A normal level is: Direct (also called conjugated) bilirubin: less than 0.3 mg/dL (less than 5.1 µmol/L) Total bilirubin: 0.1 to 1.2 mg/dL (1.71 to 20.5 µmol/L) Normal value ranges may vary slightly among different laboratories.
Normal values of direct bilirubin range from 0 to 0.4 mg/dL. Total bilirubin (direct and indirect) ranges from about 0.2 to 1.2 mg/dL (some lab values range as high as 1.9 mg/dL). Medical literature sources have minor variations in "normal" levels.
Bilirubin levels higher than 2.0 mg/dl is an indicator of jaundice in adults. For newborns, doctors will recommend treatment when bilirubin levels become higher than 15 mg/dl. What causes...
