What helps ABO incompatibility?
Last updated September 6, 2026.
**If your newborn has ABO incompatibility, bilirubin monitoring and light therapy when needed help manage jaundice.** A blood type mismatch between you and your baby can cause red blood cells to break down, leading to jaundice or anemia, but many babies need only monitoring. Your baby's clinician chooses treatment based on bilirubin levels, age in hours, and other risk factors. Regular feeding supports bilirubin removal, and severe cases may need a blood transfusion. If you mean ABO incompatibility during a transfusion, alert your care team immediately so they can stop the transfusion and provide emergency treatment.
What to do
- **Keep follow-up checks:** Attend every bilirubin check and ask whether your baby needs repeat testing for anemia.
- **Support feeding:** Offer feeds regularly, usually 8 to 12 times daily, and ask your baby's clinician for help if feeding is difficult.
- **Follow the treatment plan:** Use prescribed phototherapy exactly as your baby's care team directs.
- **Seek immediate care:** Take your baby for emergency evaluation if jaundice appears before 24 hours or comes with difficulty waking or refusal to feed.
- **Report transfusion symptoms:** Tell staff immediately if you develop fever, chills, back pain, or breathing trouble during a transfusion.
