After Phototherapy:
Appropriate measures should be taken to ensure that any measurements taken from newborns after they have received
phototherapy are taken from a site on the forehead that was not exposed to the phototherapy lights. The exact procedures
that should be used will depend on the type of phototherapy protection used as described above. Although leaving a
Bil
Eclipse
Phototherapy Protective Patch in place is not necessary once the phototherapy lights are removed, it will
ensure that the same site is used for subsequent Bili
Chek
measurements.
NOTE: Clinical studies indicate that as many as 48 hours may be required before the skin treated by photo-
therapy returns to the bilirubin level of an unexposed site.
NOTE: Newborns that are placed near windows with high exposure to sunlight may experience “natural
phototherapy”. This may be particularly true when the newborn has already been discharged home and
is returning to a hospital, clinic, or office facility for testing.
Recommended Measurement Site
Bonnets:
Although bonnets may cover the forehead during phototherapy it should be verified that they are opaque to light and
extra precautions must be taken to prevent them from moving and thereby exposing the forehead to the phototherapy
lights. Since many materials used for bonnets are not completely opaque, it is recommended that an adhesive patch be
placed on the forehead under the bonnet.
Amber Shields and Hoods:
Amber phototherapy shields or hoods which are used to protect the newborn’s eyes during phototherapy still allow some
light to penetrate. Some manufacturer’s test data indicates the light blocking cut-off is ~520 nm. Some clinical studies
have indicated that green lights (with wavelengths greater than 520 nm) may have phototherapeutic effects. The
Bili
Chek
transcutaneous bilirubin measurement has not been verified with the use of these products, therefore, it is
recommended that an adhesive patch or other light blocking method should be used in conjunction with these products
at this time.
