Meanwhile, the Badminton Association of India on Wednesday clarified that the COVID-19 tests conducted at the Odisha Open are being done according to the protocols set by the Badminton World Federation through a designated lab and there was no reason to question the authenticity of the reports.
BAI came out with the clarification after some players claimed that tests conducted by private labs in the Odisha Open were coming out negative while ICMR testing are turning out positives.
BAI rubbished the claims, saying the lab which is conducting the tests for participants in the Odisha Open is an ICMR Lab run directly by the Government of India and boasts of the highest level of precision in its protocols.
"This is the third and last tournament of the India leg and as per BWF protocol, the host country designated the lab and in this case ICMR lab was appointed which is the country's best.
"As per protocol, BWF upholds the findings of this lab only. Similar process was followed at the India Open and Syed Modi International and no exception was made at the Odisha Open as well," BAI Secretary Ajay K Singhania said in a statement.
