NOTICE
Incorrect patient results due to inappropriate sample collection
Squeezing the puncture site adds tissue fluid to the blood sample and may lead to the
premature onset of clotting despite sufficient heparinization of the sample collection
containers. This may lead to errors and discrepancies in the measurement values.
r Do not squeeze the puncture site before collecting your sample.
r Use the correct sample container for your measurement. Roche recommends using the
Roche MICROSAMPLER PROTECT for blood collection.
WARNING
Incorrect tHb and bilirubin results due to inappropriate sample handling
tHb and bilirubin concentrations in whole blood samples are sensitive to light. Light
absorption in whole blood samples may lead to incorrect results, which may endanger
patient lives.
r Immediately measure your whole blood sample after collecting it.
r If you cannot measure your whole blood sample immediately after collecting it, wrap
aluminum foil around your sample collection container.
