Asif, who tested positive for a performance-enhancing drug Nandrlone during the IPL, would come to know whether he faces more disciplinary action or not only after the 'B' sample test.
The Dawn quoted Asif's lawyer Shahid Karim as saying that they have hired a British sports medicine specialist, Dr Graham to ensure that the test is conducted under specifications of the World Anti-Doping Agency (WADA) rules.
"We have obtained the best possible help to assist us in the case as Asif is adamant he is innocent," Karim said.
Although the pacer - who spent 19-days in detention in Dubai airport for carrying a banned substance while returning home from India after playing in the IPL - has a tainted past, he said he was mentally prepared to face every situation and insisted that he never did anything wrong in his career.
"We are having the 'B' sample test for the reconfirmation. And we have to be present there. Inshallah! I will be cleared," said Asif.
Asif is presently suspended by the Pakistan Cricket Board and was not selected in next month's Champions Trophy squad, but he maintained he would come out clean and earn his place back in the national team.
