From the results obtained from the method calibration, quality controls, and patient samples tested, decide
which of the following conditions best describe the problem encountered and run the checks and actions
associated with each case:
-
High results
-
Low results
-
Erratic results
-
Only one affected sample for all the methods
-
Only one affected method for all the samples
High results
Observation
Probable cause
Action
Incubation temperature > 37ºC
High cuvette tray temperature
Contact Technical Support
High ambient temperature
Reduce the ambient temp to < 25 ºC
Low calibrator absorbance
results
Incorrect preparation of the calibrator
dilution
Use a calibrator reconstituted
correctly
Presence of bubbles or fibrin in the
calibrator tube
Use a calibrator free of bubbles
and/or fibrin
High blank reagent absorbance
Verify the blank reagent
Insufficient calibrator volume
Use a minimum volume of 200 µl
Samples concentrated by
evaporation
Insufficient sample and control volumes Use a minimum volume of 200 µl
Inadequate sample and control storage Use fresh samples and controls
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
Incorrect information in the cc
of the calibrator
Calibrator concentration configured
incorrectly
Configure the calibrator concentration
correctly
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
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
