Error Code – Definitions
Antigen Excess
A chemistry failed antigen excess test for immunoprotein reagents. This flag may
indicate a contaminated cartridge.
Bad K/NA Value
K or NA are required to calculate a CALC result. Should one or the other fail or have
an error, CALC cannot be calculated and this error is reported. Check your K and NA
values for any error conditions.
K is required to calculate a urine NA result. If K value has an error, urine NA cannot
be calculated.
Blank Absorbance High/Low
The mean absorbance measured during the reagent blank spin cycle (read window)
exceeds expected limits. The units are measured in absorbance and will characterize
reagent quality. This flag may indicate an issue with the reagent cartridge, reaction
cuvette cleanliness or sample integrity if chemistry is sample blanked.
Blank Noise (Mean Deviation)
The average difference between the absorbance readings and the line of regression is
greater than allowed. This is a check for a constant rate during the blank spin cycle.
The flag may indicate possible issues with a photometer reading.
Blank Outlier (Maximum Deviation)
A single blank absorbance data point obtained during the reagent blank read window
deviates more than allowed from the line of regression. The units are measured in delta
absorbance. Blank Maximum Deviation is a check for a constant rate during the blank
spin cycles. This flag may indicate possible issues with a photometer reading.
Blank Rate High/Low
Rate measured during blank timing period is not within specifications. Units are
measured in delta absorbance/minute. This flag may indicate an issue with reagent
contamination, reaction cuvette cleanliness or sample integrity.
Calculation Complete
Special Calculation was calculated with no result errors.
Calculation Incomplete
Not all tests required for the special calculation have valid results. Check results for
the tests in question and rerun if necessary.
Calibration Failed
Calibration was scheduled but failed one or more acceptance limits.
