German to English Medical Medical (general) Urology, Chemistry

In a typical medical test chart, blood counts are listed, and then at the beginning of the urine diagnostics section it states Urinstatus: erl., followed by different components of urine and their values.
I think this is just a routine test and there is no indication the patient is suffering from any specific condition, I just would like to know what "erl." would stand for in this context.
Thanks!
