Check the Following
• Use clean powder-free gloves during testing and keep your gloved hands
clean.
• Use calibrated pipettes and pipette tips to transfer precisely 50 µL of
control or blood sample into the treatment reagent tube.
• Make sure the pipette tip is filled properly. The accuracy of the test
depends on filling the pipette tip with 50 µL. Excess sample on the outside
of the pipette tip may produce higher test results.
• Always add the control or blood sample to treatment reagent and mix
thoroughly.
• Check the expiration on the test kit box to make sure the test kit materials
have not expired.
• Make sure the analyzer is calibrated properly. Use the calibration button
that came with the test kit you are using.
• When processing controls, check to make sure the code on the main
screen matches the code of the calibration button for the test kit.
• Avoid operating the LeadCare Ultra System in drafts or outside the
specified temperature range (16°C - 30°C / 61°F - 86°F) and specified
humidity range (12 - 80%, Relative Humidity).
• Make sure that the system and the test kit are maintained at a constant
temperature. If you move any part of the system from one place to
another, wait for the analyzer and components to reach a stable
temperature.
NOT
• Do
touch the black bars or the black cross on the sensor. This could
damage or contaminate the sensor.
NOT
• Do
touch the ends of the pipette tips. This could cause
contamination.
• When uncapping the treatment reagent tube, place cap, inside facing up,
on a clean surface.
NOT
• Do
leave the treatment reagent tube uncapped other than to add or
remove sample to/from the treatment reagent tube.
• Make sure the control or blood sample and treatment reagent mixture is
thoroughly mixed before placing onto the sensor.
The control in treatment reagent mixture will remain red after
o
mixing.
A blood sample in treatment reagent will turn brown after mixing.
o
• Make sure the sample mixture is at room temperature before placing onto
the sensors.
• Keep sensor vial closed. Remove sensors from vial only when ready to run
samples.
• If you drop a sensor, do
• Make sure 30 µL of the sample/treatment reagent or control/treatment
reagent mixture is added to the sensor.
NOT
• Do
touch the sensor while the analyzer is running a test.
NOT
use it.
