Athlete Biological Passport

The Athlete Biological Passport (ABP) is a monitoring system used in sports to detect doping. Instead of directly testing for banned substances, the ABP tracks an athlete's biological markers over time, looking for unusual changes that may indicate drug use. By analyzing blood samples, authorities can identify variations in parameters like red blood cell count or hormone levels. If these markers deviate significantly from an athlete's established baseline, it raises a red flag for potential doping. This approach allows for more sophisticated detection of performance-enhancing drugs without relying solely on conventional drug testing methods.
