Incheon 2014 has revealed it will carry out 1,920 doping tests at this month's Asian Games - a record number for the continental multisport event.
The South Korean Organising Committee has said it will test 1,600 urine samples and 160 blood samples, as well as conducting 160 tests for erythropoietin use, a form of blood doping designed to boost the number of red blood cells.
Of the total, 1,621 will be in-competition tests and 299 will be random, out-of-competition tests.
All medallists and record breakers will also be subject to tests.
The figures surpass the number of tests at past editions of the Asian Games, with Guangzhou 2010 holding the previous record of 1,500 tests.
"Most of the tests will be done on medallists," said Park Joo-hee, head of the Incheon 2014 doping control team.
"But even those who get knocked out of their events early won't be able to let their guard down."
A total of 582 drugs testers will be present at the 45 sports venues and two Athletes' Villages in Incheon and Chungju, and samples will be analysed within 24 hours of reaching the doping control centre at the Korea Institute of Science and Technology.
All results will be sent directly to the Olympic Council of Asia, bypassing Incheon 2014 and the Korean Olympic Committee.
A "no needle" policy, which was first enforced by the International Olympic Committee at London 2012, will also be in place at the Asian Games barring athletes from possessing syringes that could be used for doping.
Meanwhile, World Anti-Doping Agency officials are expected to visit the event to promote anti-doping policies, and Park said prevention is better than cure.
"The ultimate purpose of anti-doping policies isn't to nab cheaters," she added.
"It's to ensure athletes do not resort to performance-enhancing drugs."
The Incheon 2014 Asian Games will take place from September 19 to October 4.
