Asif, who faces a possible two-year ban, and his lawyer have questioned the discrepancy in the readings of the two samples. The second sample had a nandrolone concentration of 5.4 nanograms per millilitre of urine while the first had 6.2 nanograms. "We have just completed the test on Asif's B sample and it has come back positive," Asif's lawyer Shahid Karim told AFP. "But I can tell you that the quantity of nandrolone has varied, which we can contest. We hope to further this case once we get an official test report from the IPL." According to WADA (World Anti-Doping Agency) regulations, upto two nanograms per millilitre is permissible.
