The suspension, which took effect on Nov. 7, prohibits the laboratory from carrying out any anti-doping activities including all analyses of urine and blood samples.
During the ban, samples must be sent to another WADA-accredited laboratory, "ensuring that athletes can have full confidence in continued high quality sample analysis and the wider anti-doping system."
The Doha laboratory has 21 days to appeal the decision to the Court of Arbitration for Sport.
