The World Anti-Doping Agency (WADA) have suspended the accreditation of the Doha Doping Analysis Laboratory for a four-month period.
The suspension comes ahead of the Association of National Olympic Committees (ANOC) General Assembly, due to begin here tomorrow.
A statement from the organisation revealed the Laboratory was suspended as a "direct result of the more stringent quality assessment procedures enacted by WADA to ensure laboratories maintain the highest standards".
The Laboratory had only been officially accredited by WADA in August 2015.
WADA are able to suspend the Laboratory’s accreditation should it not meet requirements set out by the International Standard for Laboratories (ISL).
The monitoring process is conducted in conjunction with International Organisation for Standardisation (ISO) by independent national accreditation bodies.
The Laboratory is located close to the Aspire Academy and Aster Medical Centre, visited by International Olympic Committee (IOC) President Thomas Bach today.
During the suspension, which came into force on November 7, the Laboratory is prohibited from carrying out any anti-doping activities including all analyses of urine and blood samples
Samples are therefore required to be transported securely to another WADA-accredited laboratory.
The Doha Laboratory are able to appeal the decision to the Court of Arbitration for Sport within 21 days.
During the suspension the Laboratory will have to address all non-conformities identified by the laboratory expert group or WADA.
They will be able to apply for reinstatement prior to the expiry of the four month period should they address the issues, but WADA could extend the sanction by a further six months should they not be addressed.
The Laboratory must notify relevant authorities of the suspension, with samples not yet analysed and those undergoing procedures, needing to be securely transported to another WADA accredited laboratory in no longer that 14 days following the date of this decision.
Doha are now one of five laboratories to be suspended by the WADA.
They are Almaty, Bloemfontein, Lisbon and Madrid.
The laboratory in Moscow, meanwhile, has had its accreditation revoked following allegations of state-sponsored doping in Russia.
