"The World Anti-Doping Regulations and ISTI standards clearly state that the blood inspectors should first comply with the mandatory legal provisions of the country in which the blood collection is conducted," Sun continued.

"The blood inspector had her nurse practice registration for a hospital in Shanghai, so how could she illegally collect my blood in Hangzhou?" Sun asked.

"The most critical part was that she only showed me an expired nursing qualification certificate, rather than a valid one, and she also had no nursing professional certificate."

"I am very curious to know how the relevant medical and health institutions in Shanghai will deal with the illegal acts of the blood inspector," Sun continued.

Earlier, one of the three IDTM doping control testers in the Sun Yang case admitted he was not a trained professional Doping Control Assistant (DCA), but a construction worker.

The DCA, who insisted on anonymity, said "he had never been trained as doping control officer", adding that he was providing temporary help requested by his middle school classmate on November 15, 2018 and knew about the doping test.

"I am always busy with my construction work. I sent my testimony in a written letter to CAS and WADA and was ready to give my words at a video conference before the public hearing, but no one contacted me," said the DCA. Enditem
