Range table The operator can view the concentration ranges, reflectance values,
wavelengths and compensation data for each test parameter. The operator
gains access to the range and reflectance values by using the password that is
supplied with the analyzer.
The wavelength data (W) that are displayed are fixed values. These values
cannot be changed.
The compensation data (C) designate factors for the compensation of the
intrinsic urine color, for example, 0 means no color compensations. Higher
numbers mean stronger compensation.
Changing ranges leads to result reports which differ from the default
concentration ranges as shown in:
The concentration ranges and reflectance values can be reset to the default
values using the <Default> button.

Changing reflectance values leads to different evaluation sensitivities of the
respective test parameters. Lowering the reflectance value of the negative (NEG)
range leads to a decrease of the sensitivity of the test evaluation, and vice versa. In
this way, the sensitivity can be adjusted to the requirements of the individual
laboratory.
The correctness of results obtained after the user has altered the ranges or
reflectance values is not warranted by Roche Diagnostics. The user is responsible
for validating the consistency of results after changes have been made.
