Both parties have agreed a deal which will come into force immediately.

It has been described by the ITA as a "very important step in the FIL's anti-doping efforts" which marks a "decisive stance in support of clean sport".

The ITA will manage all aspects of the luge anti-doping programme with the FIL delegating alleged violations to them on a case-by-case basis.

They have promised a "robust" programme in full compliance with the World Anti-Doping Code, leading up to the Beijing 2022 Winter Olympics.

The FIL will still deliver anti-doping education and be in charge of long-term storage and reanalysis.

"We at the FIL are happy about the collaboration and our contract with the ITA," a joint statement from FIL President Josef Fendt and FIL secretary general Einars Fogelis said.

"We trust the ITA's expertise and we are certain that there can be no doubt about how seriously the FIL deals with its anti-doping matters. 

"We look forward to the long-term professional handling of the FIL's anti-doping matters through our collaboration with the ITA."

The ITA was formed last year, claiming to act independently of any sports organisation or national interest.

Its establishment was billed as a key step in the global fight for clean sport.

Several International Federations have since handed their anti-doping functions to the organisation, with membership now standing at more than 40.

"The ITA is grateful for the trust placed in the ITA and will work hard to provide FIL with top-class services," said ITA director general Benjamin Cohen.  

"FIL's athletes and community should feel absolutely confident that all appropriate measures are taken to ensure that athletes can compete in a healthy and clean environment with fair competitions."
