Performing a measurement
Pre-analytical sample handling Allow a standby time of at least 30 or 60 minutes (depending on reagent and sample
tube type) after collection when analyzing whole blood samples. If whole blood
samples are analyzed earlier, low result recovery may occur.
u For correct standby time, refer to the package insert.
Make sure to swivel the tube with whole blood gently before pipetting the sample, to
avoid that blood cells are settling down in the tube.
