Intended Use of the Jaundice Meter
The Jaundice Meter (JM-103) is a non-invasive transcutaneous
bilirubinometer. It measures yellowness of subcutaneous tissue in
newborn infants.
The device is intended for use in hospitals or doctors’ offices under a
physician’s supervision or at their direction to assist clinicians in
monitoring of newborn infants. The device is not intended as a
standalone for diagnosis of hyperbilirubinemia. It is to be used in
conjunction with other clinical signs and laboratory measurements.
Newborn infants whose Jaundice Meter (JM-103) test results are
indicative of hyperbilirubinemia should be evaluated by their
physician(s) for appropriate patient management. Specific neonatal
patient bilirubin levels should be confirmed by other methods, such as
serum bilirubin, prior to treatment determinations.
The Jaundice Meter (JM-103) is not intended for home use.
Limitations (Doctors’ Office Use)
Use only on infants up to 14 days of age.
For doctors’ office application, use only the sternum location when
taking measurements.
Please be aware, performance in doctors’ offices may vary from
performance in hospitals.
Precocious Jaundice
Do not use this device on infants with precocious jaundice. If there is a
possibility that the infant is suffering from precocious jaundice, as a
result of an incompatible blood type or hemolytic jaundice, it is
recommended that the total serum bilirubin be measured.

Section 2
Introduction, Features,
and Specifications
Introduction
To prevent kernicterus in newborn infants, it is very important to detect
jaundice in its early stages. The Jaundice Meter (JM-103) is a noninvasive transcutaneous bilirubinometer. This hand-held device allows a
quick, non-invasive estimate of bilirubin concentration, to be used as an
aid for the management of jaundice in newborn infants. The
measurements are taken automatically when you place the instrument’s
measuring probe against the measuring site of the infant and press it
gently; the measured value is then displayed.
Measuring Point
Measurements must be taken only on the infant’s forehead (at hospital
sites only) or sternum (at hospital sites or physicians’ offices) where a
sufficient amount of blood is circulated. A possibility exists that the
bilirubin in the subcutaneous tissue may measure low for areas with
minimal blood flow or areas in which the subcutaneous tissue is subject
to keratinization.
Although correlation with serum bilirubin was observed for both
forehead and sternum measurements, the clinical studies performed with
the Jaundice Meter (JM-103) show consistently better results with
measurements taken at the sternum versus the forehead. There is a
possibility that this difference may be more pronounced for infants that
have been exposed to sunlight, such as infants seen at doctors’ offices.
Only sternum measurements were evaluated during the studies
conducted at doctors’ offices; correlation of forehead measurements
with serum bilirubin has not been evaluated, and the device is not
intended for forehead measurements at doctors’ offices. Therefore, use
the sternum location when taking measurements at doctors’ offices.
SPECIFICATIONS
Phototherapy
WARNING:
Do not use the Jaundice Meter after initiation of phototherapy or
after an exchange transfusion as results may be inaccurate under
these conditions. Patient injury could occur.

DRAFT 20 June 2005
Explanation of the Test
Measuring Principle
The Jaundice Meter determines the yellowness of an infant’s
subcutaneous tissue by measuring the difference in the optical densities
for light in the blue (450 nm) and green (550 nm) wavelength regions.
The measuring probe has two optical paths. This method allows for a
more precise measurement of yellowness in an infant’s subcutaneous
tissue by minimizing the influences of the melanin pigment and the skin
maturity.
When the measuring probe is pressed against the forehead or sternum of
the infant, the built-in xenon lamp flashes. The light from the xenon
lamp passes through the glass fiber and illuminates the skin. The light
scatters and is absorbed in the skin and subcutaneous tissue repeatedly,
and then finally returns to the sensor side of the glass fiber. Of the light
that returns, the part scattered from the shallow areas of the
subcutaneous tissue passes through the inner core, or short-optical path,
of the fiber. The part scattered from the deep areas of the subcutaneous
tissue passes through the outer core, or long-optical path, and then
reaches its corresponding photodiode.
Page 2 - 2 Jaundice Meter (Model JM-103) User Manual (usr070)
DRAFT 20 June 2005
By calculating the difference in the optical densities, the parts that are
common to the epidermis and dermis are deducted, and as a result, the
difference in the optical densities between the two wavelength regions
can be obtained for the subcutaneous tissue only. Since the optical
density difference shows a linear correlation with the total serum
bilirubin concentration, it is converted to the estimated bilirubin
concentration and is indicated digitally.
The Jaundice Meter (JM-103) device software uses a correlation
coefficient to convert the measurement difference from the dual optical
path to an estimated bilirubin concentration. The calculation formula
used includes the correlation coefficients α and γ. These coefficients
were determined in pre-clinical testing. The equation used is as follows:
J
= α(L-S) + γ
sample
Where L and S are the long and short optical path measurements.
Use of the Device
Patient Population
The Jaundice Meter (JM-103) is indicated for use in neonatal patients
born >35 weeks gestation who have not undergone transfusion or
phototherapy treatment.

DRAFT 20 June 2005
Averaging of Measurements
Averaging measurements may allow for more precise results. Assess the
advantages of using average measurements at your facility. There was
no significant difference between the averaged measurements and the
single measurement approaches in the largest study for sternum
measurements. The mean of three measurements showed the highest
degree of correlation (r=0.965), however, the difference was minimal
with a single measurement (r=0.963).
Averaging was not evaluated in the physicians’ office study.
Action Levels
Each facility should determine their own action levels based on studies
of performance of the device on their population. Appropriate action
levels may vary depending on performance of the device, such as
precision or correlation with serum bilirubin, in the hands of the user.
Some factors that could affect performance of the device or appropriate
action levels include skin color, age, or measurement site. The bias
relative to serum bilirubin differs between hospital versus physicians’
office sites (see Appendixes A and B). Different action levels may be
appropriate for hospital versus physicians’ offices. Careful selection of
action levels should be made so that false negatives do not prevent
appropriate follow up measures.
Calibration
There is no user calibration of this device. The system does include a
checker that measures the intensity of light from the device to ensure the
light output is acceptable for proper use.
Processing of Measured Values
The Jaundice Meter (JM-103) determines the yellowness of the
subcutaneous tissue by measuring the difference in the optical densities
for light in the blue and green wavelength regions. The optical density
difference has been shown to have a linear correlation with serum
bilirubin concentration. The device computes an estimated bilirubin
concentration based on this linear correlation and provides the value on
the display.

NOTE:
At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE:
These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from
structures, objects, and people.
a. Field strengths from fixed transmitters, such as base stations for radio,
cellular/cordless telephones, land-mobile radios, amateur radio, AM and FM
radio broadcast, and TV broadcast cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment due to fixed-RF
transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the unit is used exceeds the
applicable RF compliance level, observe the unit to verify normal operation.
If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the unit.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be < 3
V/m.
