The Indian Council for Medical Research (ICMR) asked state governments to return the rapid antibody testing kits that India had procured from China over inaccurate results, China has questioned the handling of the testing kits by Indian agencies.

ICMR, India’s nodal body monitoring Covid-19 in India, has asked the state governments to return the rapid antibody test kits. Beijing has now expressed concern and questioned the handling of the kits.

“We have also learned that there are strict requirements for the storage, transportation and use of COVID-19 antibody rapid test kits. Any operation which is not carried out by professionals in accordance with the product specifications will lead to testing accuracy variations,” Counselor Ji Rong, spokesperson of the Chinese embassy in New Delhi said on Monday.

ICMR has said that the rapid antibody tests showed a wide variation in results, which is against the assurances given by the manufacturers. States have been advised to return the kits to these companies.

The Chinese ambassador added, “ICMR made it clear that rapid antibody test kits should only be used for surveillance purposes instead of replacing RT-PCR test to diagnose and confirm the cases, and States are advised to strictly abide by the methods and purpose of the usage according to ICMR’s clear instructions.”

In a statement, ICMR once again said that it advocates the swab RT-PCR test for coronavirus testing as it “is the best way to test and identify the Covid positive case”.

Citing statements issues by the two medical companies, Ji Rong defended the two Chinese companies saying, “We have noticed that Guangzhou Wondfo Biotech and Zhuhai Livzon Diagnostics already issued statements on this issue. They both stressed that their COVID-19 antibody rapid test kits had obtained the certification from the National Medical Products Administration of China (NMPA), meet the quality standards of China and exported countries, and have also been validated and approved by ICMR through National Institute of Virology (NIV), Pune and considered as satisfactory products.”
