Foreword
Safety Notes
Foreword
This instrument is designed for estimating total serum bilirubin
concentration, that is necessary for the screening of jaundice in
newborn infants. It must be used for newborn infants only.
Never press the measuring probe when it is directed to the eyes.
Doing so may cause eye damage.
To prevent kernicterus in newborn infants, it is very important to
detect jaundice in its early stages.
This hand-held jaundice meter allows a quick, non-invasive
estimate of total serum bilirubin concentration, necessary for the
control of jaundice in newborn infants.
Measurements are taken automatically by simply placing the
instrument’s measuring probe against the forehead or sternum
of the infant and pressing it gently, and the measured value is
displayed.
This facilitates use of the instrument for infants who are still kept
in incubators and provides suitable screening for jaundice. This
will also help detect jaundice in its early stages.
This instrument considers the yellowness of the skin, which
consists of epidermis, dermis and subcutaneous tissue as the
optical density difference at two wavelengths, and it calculates
the difference only for the subcutaneous tissue by measuring
the difference between the two optical paths.

Foreword
Hemolytic jaundice
Normally, in the case of hemolytic jaundice that appears before the
age of three days, measurement of total serum bilirubin concentration
must also be taken. (The correlation between the measured value
taken by the instrument and total serum bilirubin concentration drops
substantially due to physiologic factors.)
Precocious jaundice
If there is a possibility that the newborn infant is suffering from
precocious jaundice (incompatible blood type, hemolytic jaundice),
it is necessary to take frequent measurements or measure the total
serum bilirubin concentration as well. (There is a possibility that
bilirubin concentration in the subcutaneous tissue rises slower than
the total serum bilirubin concentration.)
When the newborn infant is undergoing photo-therapy
During photo-therapy, the bilirubin concentration in the subcutaneous
tissue under the area exposed to light decreases before the total
serum bilirubin concentration does, so it is necessary to limit the use
of this instrument only when photo-therapy equipment is used from
the back of the patient or affix a light-blocking patch to the measuring
point on the forehead or chest. (In areas exposed to light, there are
some cases in which only the bilirubin concentration in the subcuta-
neous tissue decreases before the total serum bilirubin concentra-
tion improves. In addition, if the total serum bilirubin concentration
increases again after therapy, there is a possibility that the bilirubin
concentration in the subcutaneous tissue will increase later.)
Measuring point
Measurements must be taken on the forehead or sternum, where a
sufficient amount of blood is circulated. (There is a chance that the
bilirubin concentration in the subcutaneous tissue is low for areas with
small amounts of blood and areas in which the subcutaneous tissue is
subject to keratinization.)
