Low Results
Observation
Probable cause
Action
Incubation temperature < 37ºC
Low cuvette tray temperature
Contact Technical Support
Low ambient temperature
Increase the ambient temp to > 15 ºC
High calibrator absorbance
results
Incorrect preparation of the calibrator
dilution
Use a calibrator reconstituted
correctly
Low blank reagent absorbance
Verify the blank reagent
Inadequate samples
Insufficient sample and control volumes Use a minimum volume of 200 µl
Presence of bubbles or fibrin in the
sample tubes
Use samples free of bubbles and/or
fibrin
Absence of the sample in the assigned
position
Place the samples in the correct
positions
Deteriorated reagent
Inadequate reagent preparation
Prepare new reagent
Refilled reagent not homogenized, or
not checked
Mix the reagent gently and verify the
blank. Avoid foaming
Physical and/or chemical deterioration
of the reagent
Prepare new reagent and verify the
blank
Incorrect information in the
configuration of the calibrator
Calibrator concentration configured
incorrectly
Configure the calibrator concentration
correctly
Insufficient reagent volume or
bubbles into the reagent bottle
Reagent volume less than 2 ml or more
than 55 ml
Refill the reagent bottle or change it
without any bubbles
Inadequate purge of the hydraulic
system
Purge the diluter Purge the washer
Incorrect aspiration or
dispensing of samples and
reagents
Losses in the diluter circuit connections
Adjust connections and purge the
diluter
Obstruction of the TIP
Purge the diluter Run a TIP cleaning
Bubbles in the tubing or diluter
Adjust connections and run a TIP
cleaning
Sensing failure
See error solving 109
Erratic Results
Observation
Probable cause
Action
Incorrect information in the
method configuration
Incorrect type of reaction chosen for
each method
Select the correct type of reaction
Method parameters configured
incorrectly
Configure the parameters adequately
Incorrect calibration
Calibrator concentration configured
incorrectly
Configure the calibrator cc correctly
Inadequate samples
Sample volumes less than 200 µl
Use a minimum volume of 200 µl
