Examinations and Tests
Your health professional will diagnose
jaundice in your newborn by doing a physical
examination and taking a medical history. As part of the medical history, your
baby's health professional may ask questions about:
- The mother's general health, particularly
during the pregnancy.
- Whether your baby was born prematurely or at
full term.
- Whether your baby had any difficulties during
delivery.
- Your baby's birth weight and whether there has been any
weight gain or loss since birth.
- Your baby's feeding and
elimination habits since birth.
- Whether the baby and mother have
incompatible
blood types (ABO or
Rh incompatibility).
- Your family history
of health conditions that could cause jaundice.
The health professional will examine your baby and evaluate his or
her skin colour. This may include pressing a finger lightly on your baby's
skin. The health professional will note whether yellowing related to jaundice
is visible only in the eyes, face, and head or if it is also noticed on the
chest and lower body. He or she may also look for signs of
underlying conditions that can cause jaundice.
A transcutaneous jaundice meter may be used to measure your baby's
bilirubin level. If the results are concerning, a
bilirubin test may be done to more precisely measure
the bilirubin level in your baby's blood. The results will help your health
professional determine whether treatment is needed.
If the health professional thinks that another condition is causing
the hyperbilirubinemia, more tests may be done. For example, if the health
professional thinks that a difference in the baby's blood type and the mother's
blood type (ABO or Rh incompatibility) is causing the hyperbilirubinemia,
blood type tests may be done on the mother's and
baby's blood.
Many mothers and their newborns leave the hospital within 48 hours
of the baby's birth, often before signs of jaundice develop. Your baby should
have a follow-up examination with your health professional within the first 5
days after birth. Also, call your health professional if at any time you notice
a yellow tinge to your baby's skin and eyes.
