Worried about high blood bilirubin levels but unsure if they are abnormal? This tool evaluates your jaundice index using standard medical algorithms based on total serum bilirubin concentration (in μmol/L) and age group (newborn or adult/child). The jaundice index is a key clinical indicator for assessing bilirubin metabolism. The tool outputs the index classification, flags abnormal statuses, and provides the normal reference range for the specific age group, offering data support for health self-checks.
What should I do if the input value is out of range?
This tool only supports values between 0-500 μmol/L. If your value exceeds this range, you will be prompted to re-enter it. In actual clinical practice, extremely high values require emergency medical attention.
At what jaundice index does a newborn need medical attention?
Levels >250 μmol/L (for premature infants) or >340 μmol/L (for full-term infants) are considered high risk and require immediate medical attention. The tool's abnormal status flag can serve as an initial reference.
The input value must be in μmol/L. If your report uses mg/dL, you need to convert it (1 mg/dL ≈ 17.1 μmol/L). The newborn option is strictly for infants within 28 days of birth. Results are for reference only and cannot replace a professional medical diagnosis. For batch testing, please use professional medical systems.
We recommend interpreting the results alongside your full laboratory report. When adult bilirubin is >20 μmol/L or newborn bilirubin is >250 μmol/L, even if the tool flags it as abnormal, further testing is needed to check the ratio of direct to indirect bilirubin. For example: Entering 200 μmol/L + checking the newborn option → High-risk index (Reference range: <85 μmol/L), indicating that phototherapy intervention may be required.
