The aim of testing is to protect clean athletes through the detection and deterrence of doping.


Any athlete under the testing jurisdiction of UIM may be tested at any time, with no advance notice, in- or out-of-competition, and be required to provide a urine, blood sample or blood for a Dried Blood Spot (DBS) analysis.


Sample Collection Process


  1. Athlete Selection: An athlete can be selected for testing at any time and any place.
  2. Notification: A Doping Control Officer (DCO) or chaperone will notify the athlete of their selection and outline their rights and responsibilities.
  3. Reporting to the Doping Control Station: The athlete should report to the doping control station immediately after being notified. The DCO may allow a delay in reporting for a valid reason.
  4. Sample Collection Equipment: The athlete is given a choice of individually sealed sample collection vessels and kits to choose from.
  5. They must inspect the equipment and verify the sample code numbers.
  6. Collecting the sample:


  • For a urine sample:
    • Providing the sample: The athlete will be asked to provide the sample under the direct observation of a DCO or witnessing chaperone of the same gender.
    • Volume: A minimum 90mL is required for urine samples. If the first sample is not 90mL, the athlete may be asked to wait and provide an additional sample.
    • Splitting the sample: The athlete will split their sample into A and B bottles.
    • Sealing the samples: The athlete will seal the A and B bottles in accordance with the DCO’s instructions.
    • Measuring specific gravity: The DCO will measure the specific gravity of the sample to ensure it is not too dilute to analyze. If it is too dilute, the athlete may be asked to provide additional samples.


  • For a blood sample:
    • The athlete will be asked to remain seated and relaxed for at least 10 minutes before undergoing venipuncture (only for the Athlete Biological Passport (ABP) blood samples).
    • The Blood Collection Officer (BCO) will ask for the athlete’s non-dominant arm, apply a tourniquet to the upper arm, and clean the skin at the puncture site.
    • The BCO will draw blood from the athlete and fill each Vacutainer blood tube with the required volume of blood.
    • The BCO will place the Vacutainer tubes into the A and B kits (only one vial may be necessary if the blood sample is collected as part of an ABP program).
