3.0 INTRODUCTION
Jaundice is a condition characterized by yellowing of the skin and eyes that is caused by an excess of bilirubin in the
blood. Bilirubin is a normal waste product resulting from the breakdown of red blood cells and is removed from the
body by the liver. Prior to birth, bilirubin in an infant is processed by the mother’s liver and excreted. After birth, an
infant must eliminate bilirubin without the mother’s help. It may take the infant’s system several days to begin
eliminating bilirubin from the blood faster than it is produced. Infants who are born prematurely, who are underfed, or
who belong to certain ethnic groups are at increased risk of developing jaundice. The initial screening of jaundice is
the observation of yellow skin. This is a subjective determination prone to errors due to differing skin colors and
gestational ages. Bilirubin levels normally peak in full-term infants 4 to 5 days after birth and may peak later in
premature infants. If the infant’s serum bilirubin levels continue to rise the infant is at risk for kernicterus (the deposit
of bilirubin in the brain at toxic levels which can cause permanent neurologic impairment).
4.0 PURPOSE OF THE DEVICE
The BiliChek® Non-Invasive Bilirubin Analyzer is a non-invasive transcutaneous bilirubinometer, which predicts total
serum bilirubin levels before, during, and post phototherapy in neonates without regard to gender, gestational age, race,
or bodyweight. Neonates whose BiliChek test results are indicative of hyperbilirubinemia must be evaluated by their
physician(s) for appropriate patient management. The BiliChek provides a numerical measurement of predicted
bilirubin count in mg/dL or µmol/L within a clinically beneficial range that has been correlated with total serum
bilirubin concentration measured by High Pressure Liquid Chromotography (HPLC). The device is used by Health
Care Professionals to assist clinicians in monitoring the status of neonates for the development of hyperbilirubinemia.
5.0 THEORY OF OPERATION
The BiliChek works by directing white light into the skin of the newborn and measuring the intensity of the specific
wavelengths that are returned. By knowing the spectral properties of the components within the skin, one can subtract
out the interfering components and determine the concentration of bilirubin.
Each photon has a characteristic wavelength. As light enters skin tissue it can collide with the structural components
such as collagen fibers. When a collision occurs, the photon loses energy and the direction of travel is changed. This
is called a scattering event. If enough of these scattering events occur, the photon completely loses its energy and is
absorbed. If a photon is scattered such that it is re-emitted from the skin, it is reflected.
Photons with longer wavelengths (in the red region of the spectrum) are scattered less than photons with shorter
wavelengths (in the blue region of the spectrum). This phenomenon is called wavelength-dependent scattering and
explains why the skin appears red when you shine a bright light through it. It is also one of the reasons why the
optical properties of the newborn’s skin changes with advancing gestational and post-natal age. As the skin matures,
it becomes thicker and there is greater keratinization of the cell membranes which increases the scattering of
incident light.
Photons of specific wavelengths are also preferentially absorbed by certain molecules. By plotting the absorption
against the wavelength one can visualize characteristic absorption spectra of the particular molecules. For example,
melanin has a near-linear absorption spectrum in the visible spectrum and, like the scattering phenomenon, there is
greater absorption of photons with shorter wavelengths than in the red region of the spectrum. Conversely,
hemoglobin is a much more complicated absorber which is compounded by the fact that oxyhemoglobin and
deoxyhemoglobin have different profiles. The peak absorption of photons by bilirubin occurs at a wavelength of
460nm. This is in the blue portion of the spectrum and is the reason why blue lights are sometimes preferred for
phototherapy. It is also in a region of the spectrum at which hemoglobin absorption is relatively low.

ENGLISH
The light reflected from the skin of neonates and collected by the BiliChek is analyzed with a highly sophisticated,
proprietary algorithm to generate a serum bilirubin measurement. The major skin components (figure 1) which impact
the spectral reflectance in newborns are (1) dermal maturity, (2) melanin, (3) hemoglobin, and (4) bilirubin. The
intensity of the reflected light is converted to absorbance units, Optical Density (OD), for analysis. The total OD at
each measured wavelength is equal to the sum of the component ODs. This is represented mathematically as:
OD
total
= OD
derm
+ OD
mel
+ OD
heme
+ OD
bili
By utilizing known spectral characteristics of each component, the contribution to the total OD can be sequentially
subtracted until bilirubin is all that is remaining.
FIGURE 1
Non-Invasive Skin Spectral Components1

Each of these components have also been considered in the development of the algorithm by which the BiliChek
computes the bilirubin measurement. By measuring the intensity of the reflected light at more than 100 individual
wavelength bands across the visible spectrum, a spectral analysis can be performed. By normalizing against a
reference standard, the BiliCal™, the variations over time of the bulb and the photo-detectors are eliminated. The peak
absorption of the bilirubin at approximately 460nm is measured by subtracting the absorption of the other components
from the total skin absorption. This is represented by the equation below.
OD
bili
= OD
total
- OD
mel
- OD
heme
- OD
derm
The absorption of light by a molecule is proportional to its concentration. Therefore, the absorption of bilirubin, as
calculated above, is proportional to the concentration of bilirubin in the subcutaneous capillary beds and subcutaneous
tissue. By subtracting the contribution of the aforementioned components, the bilirubin absorbance can be quantified and
is correlated to the laboratory total serum bilirubin levels.

Protecting a Measurement Site
Exposure of a neonate to phototherapy creates changes in the skin due to the therapuetic affects of phototherapy lights.
If a small portion of the newborn skin is protected from the therapeutic affects of phototherapy lights, the relationship
between the skin bilirubin in the protected skin site and blood bilirubin is likely to be maintained. The accuracy of the
BiliChek® transcutaneous bilirubin measurement taken from a protected site during and after phototherapy has been
determined in a controlled clinical study. The recommendations in the User Instructions are based on the results of this
study.

NOTES
Certain medical conditions and medications are known to disrupt bilirubin-albumin carrying capacity and binding.
These factors may alter the transcutaneous bilirubin measurement by increasing or decreasing the bilirubin deposition
in the skin especially at high total serum bilirubin concentrations (>15 mg/dL or 255 µmol/L). Therefore, additional
caution should be used in interpreting the BiliChek measurement in patients with serious illnesses or complications
such as septicemia, PDA, IVH, and RDS. In these patients, a separate serum bilirubin measurement should be
considered if the BiliChek indicates elevated bilirubin levels.
There is limited data on use of the BiliChek on patients under intensive phototherapy (>30 µW/cm2/nm or 1.5 m
Wcm2), double-sided phototherapy, or after exchange transfusions. Caution should be used in interpreting BiliChek

9.2 Charger Base
The charger base contains two wells, A and B, which recharge the battery pack in the BiliChek® and a spare battery pack,
respectively. The two small lights on the front of the charger base (Battery Status Indicators or BSI) indicate the operation
of the battery charger and battery charge status.
THE CHARGER BASE
•The BiliChek is placed in the left hand well “A” with the display window facing the operator.
•The spare battery pack is placed in the right hand well “B” with the latch up and facing the operator.
CAUTION: The BiliChek unit will not fit in well “B” of the charger base. The battery pack
can fit into well “A”, but may not make correct connection to the charger base.
•In order to maintain optimal battery performance and battery life, the battery packs should periodically be fully
drained of power. The charger base has the ability to manually drain the battery by using the “Charge/Deep
Discharge” switch located on the bottom of the charger base. It is recommended by the manufacturer to discharge
each battery pack every month. To drain a battery pack of power, place the Deep Discharge switch in the
“right” ( ) position and place the BiliChek battery pack in well B of the charger base. The discharge/recharge
cycle will take approximately 4.6 to 9.2 hours depending on the amount of charge in the battery pack. The green
light will illuminate when the battery pack has completely discharged and recharged. After both battery packs have
been discharged and recharged, place the Deep Discharge switch in the “left” position ( ).
NOTE: Only the battery pack in Well B will be deep discharged and recharged.
CAUTION: Leaving the Deep Discharge switch in the “right” position at all times will drain
the battery pack before every recharge. This will increase the duration of the
recharging cycle and may reduce the overall life of the battery packs.
NOTE: If a battery pack is moved or bumped during the deep discharge cycle this may cause the deep
discharge cycle to begin again.

•The unit will perform a self-test, momentarily displaying all LCD indicators,
Measurement Status Indicator, software revision, configuration screen and end at
the home screen.
NOTE: Press and hold F1 to illuminate the back light of the display window. This option is not
available in the Set-up Mode.
NOTE: The home screen will remain until the TRIGGER button is pressed or the user Set-up Mode is
entered.
CALIBRATION
•Press and release the TRIGGER button to start calibration.
•Three dashes (---) will flash in the display window and the MSI will be amber if
a BiliCal Tip is in place, indicating the system is ready to calibrate. If a
BiliCal Tip is not in place the MSI will be red. Attach a BiliCal Tip before
continuing.
•Press and release the TRIGGER button. The dashed lines will stop
flashing indicating that the system is calibrating.
•When calibration is complete the MSI will be amber, you will hear a beep (if the
audio is on), and the display window will read “005”.
NOTE: If a problem occurs during calibration an error message will be displayed. Refer to the
Troubleshooting Section of the manual for instruction.
NOTE: To exit during calibration or measurement, press F1 and F2 to return to the home screen.
The user will then need to repeat the procedure.
NOTE: This unit is equipped with a Critical Power-Off feature. After completing the calibration, the
unit will sound an alarm if no measurement is performed within a preset period of time. The
unit will power-off 20 seconds later if F1 or F2 is not pressed. If the unit automatically shuts
off, it is necessary to perform another calibration after restarting.

12.2 Completing a Patient Test -- Performing the Patient Test
TAKING A MEASUREMENT
•After performing the calibration, pull on the BiliCal™ tab and peel away the protective
covering and calibration material from the BiliCal Individual Calibration Tip and
dispose. The display should be blinking “005” indicating that 5 measurements need to be
made.
•Press and release the TRIGGER button. The unit is now activated and ready to
take a measurement. Gently press the BiliCal Tip against the infant’s forehead. The
Measurement Status Indicator (MSI) on the display will change from amber to green
when proper pressure is applied. Do not continue to increase pressure, this will result in
an E04 error message.
•The display will read “005” and will stop blinking when proper pressure has been
applied. The measurement should take less than 2 seconds. At the end of the
measurement, a beep will sound (if audio is on) and the display will change to “004”.
•Lift the BiliCal Tip off the center of the infant’s forehead between each
measurement. Press and release the trigger button before reapplying the BiliCal Tip on
the infant’s forehead for each measurement. The current measurement being taken will
be indicated on the display (005...003...001) and the unit will beep one time (if the audio
is on) for each measurement successfully completed.
•Upon completion of the five measurements, a beep sounds (if the audio is on) and the
test results are displayed with the current time and date.
•Remove and dispose of the BiliCal Individual Calibration Tip.
•Place the Protective Cover onto the BiliChek per manufacturer’s recommendation. (If
the protective cap is lost a BiliCal may be used to protect the fiberoptic probe.)
•The Hand-Held Unit will turn off automatically.
TECHNIQUE TIP:
To assist the user with applying proper pressure while performing a patient measurement, a Measurement Status Indicator
(MSI) has been included in the display. The following are the MSI color coding indicators:
•The MSI will be red until the user applies a BiliCal Individual Calibration Tip or during an error message.
•The MSI is amber when the user performs a calibration.
•The MSI is amber when the user begins a measurement.
•The MSI turns green when proper pressure is applied during a patient measurement.
•The MSI will return to amber if excessive pressure is applied.
•If during a measurement the user moves out of the “pressure zone” the MSI turns red and an E04 error is
displayed. Press and release F1 and F2 at the same time to retake the measurement. All previous successful
measurements are saved.
TECHNIQUE TIP:
Be sure to hold the BiliCal Individual Calibration Tip flat against the patient’s forehead and in place until the test is complete.
By visualizing the skin pressed flat all around the clear ring, the user can ensure the Disposable Tip is flat against the skin
surface. Once proper pressure is applied, the display will stop blinking and the MSI will turn green. If the BiliChek is moving
during a measurement, the error code E04 is displayed.
NOTE: A single tone indicates a successful reading (if the audio is on). A double tone indicates that the
reading was not successful, and an error code is displayed.
NOTE: If an error code is displayed, you do not need to calibrate the unit again. After an error is
displayed, press and release F1 and F2 at the same time to return to the previous measurement
screen. Reapply the tip to the baby’s forehead and take another measurement.
WARNING: It is critical to calibrate the unit and apply a new BiliCal Individual Calibration Tip immediately
prior to performing a test. Inaccurate test results will occur if this is not done. Removal of the tip after calibration
and prior to a patient measurement will result in loss of calibration. The entire calibration sequence must be
repeated with a new BiliCal Tip.
