Over measuring range
The measured absorbance is above the
calibration range of the test Dilute the sample and repeat the
measurement
Under measuring range
The measured absorbance is below the
calibration range of the test
If possible, select a test with a lower
measurement range or use a cuvette
with a longer path length
