How to Use the Bili Tool (PediTools Bili 2022)

This is a free online tool that helps calculate if your baby’s bilirubin level is in a safe range.

Website: https://peditools.org/bili2022/

Here is what to enter:

1. Your baby’s gestational age (how many weeks pregnant you were)
2. Your baby’s age in hours (how old they are now)
3. Your baby’s bilirubin number (from a blood test)
4. Check the box for “neurotoxicity risk factors” if your baby has HDFN or a positive Coombs test

Then click Calculate.

The tool will show:

• If your baby is in a safe range
• If they need phototherapy now
• If they are close to needing a transfusion

What You Can Do as a Parent

• Watch for yellowing of the skin or eyes, especially in the first two days
• Ask your care team what your baby’s bilirubin levels are
• If your baby has HDFN or a positive DAT (Coombs), make sure they are being checked often
• Know that treatments like phototherapy are safe and work well when started early
