Dopningsprofiler

Dopningsprofiler, often referred to as athlete biological passports (ABP), are a system used in sports to monitor biological markers in an athlete's body over time. The primary goal is to detect doping indirectly by identifying abnormal fluctuations or patterns in these markers, rather than directly detecting a prohibited substance. This approach aims to combat the use of doping substances that are difficult to detect through traditional urine or blood tests, such as those that can be endogenous (naturally occurring) or have short detection windows.

The ABP system typically involves the collection of blood and urine samples from athletes at various times, both in and out of competition. These samples are analyzed for a range of biomarkers, which can include hematological markers (related to red blood cells and oxygen transport), steroid markers (related to hormones), and other physiological indicators. The collected data is then used to establish an individual profile for each athlete.

This profile serves as a baseline against which future results are compared. Significant deviations from an athlete's established normal range, or a pattern of fluctuations indicative of doping, can trigger an investigation. This indirect method of detection is considered a powerful tool in the fight against doping, as it can identify the effects of doping even when the specific substance is not detected. The implementation and interpretation of dopningsprofiler are managed by anti-doping organizations.
