Uefa will retrospectively study 900 doping samples given since 2008 as it attempts to combat use of performance-enhancing drugs in European football, the BBC reports.
Though it will not lead to future punishments, the governing body intends to identify the scale of steroid use.
Uefa will also carry out blood testing in more competitions from 2013-14, and consider using biological passports.
A proposal for 10-match European bans for players and officials found guilty of racism has also been ratified.
For racist incidents involving spectators, a partial stadium closure for the first offence and a full stadium closure for a second, coupled with a fine of 50,000 euros (£42,800), will be applied.
The new measures were on the agenda at Uefa’s executive committee meeting, held in London prior to Saturday’s Champions League final between Borussia Dortmund and Bayern Munich.
