Fairfax Media stated Sunday night that Botha's blood tested positive for banned stimulant Phentermine after a sample was taken last Tuesday.
An ASADA spokesman said the body was not in a position to make a formal comment on the issue but typically boxing title fights fell out of their jurisdiction.
Williams deservedly defeated Botha on points at the Brisbane Entertainment Centre last Friday, but was out on his feet in the 10th round when the fight ended despite everyone believing it was a 12-round contest.
Fairfax's report did not mention which body tested him and how the results were returned in five days.
However, International Boxing Federation committee member John Hogg said "I sent Frans for a complete medical which tested him for hepatitis and AIDS etc but that is the only testing required of professional boxers," Hogg told The Courier-Mail.
The report suggests results of a blood sample submitted by the 44-year-old South African in Brisbane last Tuesday under WBA regulations show he had Phentermine - a banned stimulant - in his system.
The drugs test, which has now been forwarded to the WBA's global headquarters in Panama, also detected Benzodiazepine, which suggested Botha was also using a valium-type product.
Williams' manager, Khoder Nasser, was the promoter of the fight night last Friday and did not respond to requests from The Courier-Mail for comment on the doping test claim against Botha.
Hogg said Nasser could have asked Botha to submit to further testing. "But Frans could also rightly refuse,' he said. "Then again, what is the point of testing a fighter on a Tuesday if you only get the result after the fight.
"The only way he would have been tested is if Nasser made him but then which body would Nasser have got to do it?"
Hogg refuted Botha's claims that the South African though his fight was meant to last 12 rounds.
"It was agreed to 10 before the fight and both camps knew it," Hogg said. "I knew about it being reduced to 10 and so did all the officials and ring staff.
"For Botha to suggest he thought it was 12 is ridiculous."
