Converting factors for diagnostic parameters

In our lab reports the test results as well as the norm values are listed in internationally valid SI - units. When assessing follow - up test results you possibly want to compare different values by using identical measuring units. Conversion factors for those parameters for which we have adapted the measuring unit are listed below.

To convert from one measuring unit to the other the measured value must be multiplied with the corresponding conversion factor(i. e. bilirubin in mg/dl x 17.104 = bilirubin in µmol/l).
