• Seat patient with head back
and eyes upward toward the
ceiling and away from the eye
being tested. (A).
• IMPORTANT: Do NOT pull
the eyelid away from the
eye; moving the lid down
will break the tear lake and
make collection difficult.
• Ask the patient to blink 3 times,
then move the pen into place.
• Lower the pen allowing the
bottom of the tip to come into
contact with the lower eyelid
and the line of moisture along
the inner eyelid margin (B).
• Move the tip beyond the
eyelashes near the canthus
(C & D).
• Avoid touching the sclera.
• Press down lightly with the pen
on the lower eyelid to collect
tears (E).
• Fluid is wicked upwards from
the underside of the tip of the
test card.
• Allow patient to blink normally.
• If there is not enough tear to
collect immediately, do not
peck.
• Gently press down on the
lower eyelid with the tip of the
pen. Without removing it from
the lid margin, slide the pen
along the outer one-third of the
lid margin until a tear sample is
obtained (F).
• Poor tear collection technique
can result in Below Range
readings and the test should be
repeated with a new test card.

• Re-dock pen and allow to
charge for 5 minutes. A battery
icon should appear to show
pen is properly docked.
• Remove pen from magnet. You
should hear several “clicks”.
• Enter correct calibration code,
printed on top of test card, into
reader after docking pen during
test (C).
• Test ECC, if reading is 334 ±3
the pen is working correctly
and should now be charged
for 1 hour.
• If error returns, remove pen
from reader again and reset
pen (refer to next section).
• When “clicks” stop, re-dock
pen in reader cradle and allow
pen to fully charge.
• Test using an ECC, if reading
is 334 ±3 the pen is working
correctly.

OR “ABOVE RANGE”
DISPLAYED DURING
PATIENT TESTS
• Store control solutions at room
temperature near the reader,
and test cards in test card tray,
to avoid damage.
• Leave system turned on 24
hours a day, 7 days a week.
This ensures warm-up time
never disrupts testing.
• Ensure that all guidelines listed
in the previous section are
being followed.
• Do not test patients if they have
used therapeutic eye drops
within the last 2 hours.
• Do not test patients if you have
administered anesthetic or
dilating eye drops within the last
15 minutes.
• For further guidance regarding
tear collection refer to the
TearLab Collection Guide on
the reverse side or view the
