A doping control laboratory in Madrid has had its accreditation suspended by the World Anti-Doping Agency (WADA).

The news was confirmed on Monday, with WADA announcing the decision had been taken "as a direct result of the WADA Foundation Board's 19 March decision to declare the Spanish Anti-Doping Agency (AEPSAD) non-compliant."

In April, labs in Moscow, Lisbon and Beijing also had their accreditations revoked after they were found to be non-compliant with the International Standard for Laboratories.

Under WADA rules, at least 60 per cent of samples analysed by any lab must have been provided by an anti-doping organisation other than that of the country within which the lab is situated.

During the 12-month period from March 19 2015, 69 per cent of the Madrid lab's samples were received from AEPSAD, prompting WADA's sanction.

"The suspension, which takes effect immediately, prohibits the Laboratory from carrying out any WADA-related anti-doping activities including all analyses of urine and blood samples," a WADA statement read.

"It is also important to note that, in light of the above, Spain's other laboratory in Barcelona (Fundacio Institut Mar D'Investigacions Mediques - IMIM) has maintained its accreditation."
