The Markers

The Ruma Markers used by us are polyethylene glycols – also called macrogols – which only pass through the body due to their specific properties and are excreted unchanged through the urinary bladder. We make use of this complete lack of any side effects to mark the urine sample of the test subject without any risk or interactions with other substances and thus to prove the identity of the urine donor.
At present, we use 6 different marker substances, which have very different characteristics in the analysis. As neither the test subject nor the doctor knows about the marker that has been administered, even any potential swapping of the already marked urine sample is detected safely.
Under normal circumstances the marker requires 30 minutes to reach the bladder naturally. In rare cases, 1:250,000, 45 minutes might be required for delayed urination. This will lead to a minimum time that must elapse till the submission of urine sample. Longer waiting periods, even lasting many hours, are also possible. The laboratory requires only the first urine sample after administering the marker.
