WADA publishes annually an overview of the analytical results reported by the accredited anti-doping laboratories.

The 2010 Laboratory Statistics includes analyses conducted by the WADA accredited laboratories for in- and out-of-competition testing. There were 35 WADA accredited laboratories in 2010.

In 2010, there was a decrease of 19,601 samples analyzed compared to 2009. A total of 277,928 samples were analyzed in 2009, and 258,267 samples were analyzed in 2010.

There was a decrease in the number of Adverse Analytical Findings and Atypical Findings from 5,610 in 2009 to 4,820 in 2010. There was a slight decrease in Adverse Analytical Findings (AAFs) and Atypical Findings (ATFs)— from 2.02% in 2009 to 1.87% in 2010.

WADA publishes annually an overview of the analytical results reported by the accredited anti-doping laboratories.

It is important to note that the AAFs and ATFs in this report are not to be confused with adjudicated or sanctioned Anti-Doping Rule Violations (ADRVs).

An AAF is defined in the World Anti-Doping Code (Code) as "a report from a laboratory or other WADA approved entity that, consistent with the International Standard for Laboratories and related Technical Documents, identifies in a sample the presence of a Prohibited Substance or its Metabolites or Markers (including elevated quantities of endogenous substances) or evidence of the use of a Prohibited Method".

These figures may not be identical to sanctioned cases, as the figures given in this report are all subject to the results management process conducted by Anti-Doping Organizations (ADOs), which includes matching with Therapeutic Use Exemptions (TUEs).

In addition, ATFs are defined in the World Anti-Doping Code as "a report from a laboratory or other WADA-approved entity which requires further investigation as provided by the International Standard for Laboratories or related Technical Documents prior to the determination of an AAF”.

ATFs may correspond to multiple measurements performed on the same athlete, such as in cases of longitudinal studies.

Therefore, the number of AAFs and ATFs reported by laboratories may not correspond with the number of cases sanctioned (ADRVs) by ADOs.
