Testing Procedures in Anti-Doping

Anti-doping testing procedures are the backbone of clean sport. The World Anti-Doping Agency (WADA) defines uniform standards that are implemented in cycling by the UCI and national anti-doping agencies. Modern testing procedures combine biological passports, targeted controls and innovative detection methods.

Fundamentals of Anti-Doping Testing Procedures

Anti-doping testing procedures in cycling follow the strict guidelines of the WADA Code and serve to protect clean athletes and the integrity of sport. The procedures include various types of tests that are conducted both during and outside of competitions.

Objectives of Doping Controls

The testing procedures pursue several central objectives:

  1. Deterrence - Deter potential doping offenders through close-knit controls
  2. Prevention - Prevent doping through transparent procedures
  3. Detection - Identify violations of anti-doping rules
  4. Fairness - Ensure fair competition conditions for all athletes
  5. Health Protection - Protect athletes from dangerous substances

Types of Doping Controls

Anti-doping testing procedures distinguish between different types of controls, each serving specific purposes.

Competition Controls

Competition controls (In-Competition Testing) take place during or immediately after races. At major cycling races like the Tour de France, several riders are tested daily.

Special Features:

  • Control takes place within 12 hours after race end
  • Winners and top finishers are generally tested
  • Additional random selection of other riders
  • Higher probability of stimulant detection

Training Controls

Training controls (Out-of-Competition Testing) are unannounced tests outside of competitions. These are considered particularly effective, as many doping substances are primarily used during training phases.

Characteristics:

  • No advance notice possible
  • Conducted at any time of day, including early morning
  • Athletes must report location via ADAMS system
  • Extended analysis spectrum possible

Targeted Controls

Targeted Testing is based on suspicions, tips or conspicuous parameters in the Biological Passport.

Triggers for targeted controls:

  • Conspicuous values in the Biological Passport
  • Tips from whistleblowers
  • Suspicious performance improvements
  • Connections to known doping networks
  • Anomalies in previous test results

Process of a Doping Control

The process follows standardized international protocols to ensure the integrity of samples and the rights of athletes.

Step 1: Selection and Notification

The athlete is notified by a doping control officer (DCO). The notification must be made in person and is binding from this moment.

Important Rules:

  • Athlete must identify themselves immediately
  • Control cannot be postponed
  • Accompanying person may be called in
  • Athlete remains under constant observation
  • Fluid intake only allowed under supervision

Step 2: Going to the Control Station

The DCO accompanies the athlete to the doping control station. At competitions, this is usually located in close proximity to the finish area.

Step 3: Identity Verification and Form Check

At the control station, identity is verified and the official form is filled out.

✓ Name and date of birth
✓ Sport and discipline
✓ Competition or training control
✓ Medication intake (last 7 days)
✓ Dietary supplements
✓ Accompanying person (if present)
✓ Date and time of notification
✓ Athlete's signature

Step 4: Selection of Sample Container

The athlete selects one from several sealed sample container sets themselves. This prevents manipulation.

Components of a sample set:

  • A-sample container (for initial analysis)
  • B-sample container (for possible re-test)
  • Sealed packaging with number code
  • Documentation form with identical number

Step 5: Sample Collection

The actual sample collection takes place under direct observation to exclude manipulation.

Urine Sample:

  • Minimum amount: 90 ml
  • Observation of collection (same-gender DCO)
  • Athlete can provide multiple partial samples until minimum amount is reached
  • pH value and specific gravity are measured immediately

Blood Sample:

  • Collection by qualified medical personnel
  • Usual volume: 2-3 tubes of 3-6 ml each
  • For blood passport and substance detection
  • Storage at controlled temperature

Step 6: Sealing and Documentation

The athlete seals the samples themselves and verifies the code numbers.

  1. Division of urine sample into A and B sample
  2. Closure with security seal
  3. Verification of code numbers for match
  4. Signature on documentation form
  5. Receipt of a copy for personal records

Step 7: Transport to Laboratory

The samples are transported in special cooling containers to a WADA-accredited laboratory.

Transport Standards:

  • Protected from manipulation
  • Temperature control (blood samples: 2-8°C)
  • Documented chain of custody
  • Maximum 36 hours until laboratory arrival

Analysis Techniques

WADA-accredited laboratories use state-of-the-art analysis techniques to detect prohibited substances.

Frequently Asked Questions About Testing Procedures

Can I refuse a doping control?

No. Refusing a control is treated like a positive doping finding and leads to a ban of 2-4 years.

What happens with a positive A-sample finding?

The athlete is informed and can request analysis of the B-sample. If the B-sample confirms the finding, a disciplinary procedure follows.

Do I have to be observed during the control?

Yes, during urine collection there is direct visual observation by a same-gender DCO to exclude manipulation.

What are Therapeutic Use Exemptions (TUE)?

Medical exemptions for athletes who need prohibited substances for health reasons. Must be applied for and approved in advance.

How long are my samples stored?

Urine and blood samples are stored for up to 10 years at -20°C for possible re-testing with improved methods.
