The BWF held the draws for the Rio Games on Tuesday and included Vladimir Malkov and Natalia Perminova in the men's and women's singles as well as the men's doubles partnership of Vladimir Ivanov and Ivan Sozonov.
"We have had a rigid drug-testing programme, especially leading up to Rio 2016 and all four Russian athletes have been tested in and out of competition and their samples have been analysed outside of Russia," Secretary General Thomas Lund said during the draw.
"We believe the information that we have provided on these athletes lives up to the criteria for participation in the Badminton Competition at Rio 2016, but it is left for the IOC to validate.
"We have chosen to keep them in the draw, pending that validation."
The badminton competition at the Rio Olympics takes place from Aug. 11-20.
