Barry was concerned about what it might not find, considering Botha admitted he received a cortisone injection recently. Botha recently complained of an arm injury which threatened his involvement in the Parker fight so Lonergan gave him approval to receive a cortisone injection.
"I'm relaxed about it,'' Lonergan says. "Athletes take cortisone to lubricate joints and take pain away from joints. It's a common thing to do. From that point of view, I shrugged my shoulders.''
Barry, on the other hand, gave one of his intense stares. After all, Botha was stripped of the IBF heavyweight title he won in 1995 for having nandrolone in his system - he said he took it inadvertently, blindly trusting people in his camp to give him the right things, becoming the first boxer to test positive - and allegations of a failed test were also levelled at him by Khoder Nasser after his controversial defeat to Sonny Bill Williams in February.
"You don't have to be a rocket scientist to work out he is a very experienced guy in and out of the ring,'' Barry says of the South African. "He knows all the tricks. I'm sure he's told this story many, many times in the past and got away with it many, many times in the past.''
He also wasn't impressed Lonergan hadn't informed him. Lonergan wasn't bothered.
"Do I think he's taking cortisone as a masking agent?'' he ponders. "I don't know. Probably not. Do I think Kevin Barry gets paranoid about a whole lot of things? Yeah.
"It all comes down to Thursday night. Performance enhancing drugs or not, I think Joseph Parker will knock Francois Botha out regardless of whether he has anything in his system and, in my opinion, I don't think he does.''
Parker was almost a bystander throughout the 45-minute sideshow. Botha was the centre of attention as soon as he burst through the doors of Duco's offices in central Auckland and immediately called out 'Baby Joseph', as he's been referring to him all week.
Parker grinned and replied, 'Hey, Granddad'. It was about his only meaningful contribution.
"I am learning a lot off him,'' Parker says looking at Botha. "I'm grateful I am in the situation I am in at the moment in my boxing career.
"I need to learn because, if I don't back myself up, then I will let someone run all over me. But the Buffalo, everything he says is funny to me. He's a real character. We are good friends but, in the ring, different story.''
Botha thought today's public drugs test would prove he's clean and ensure Thursday's fight was about nothing more than boxing. Little in the world of professional boxing is like that and suspicion follows Botha wherever he fights.
"Listen to me, man, I have permission to do this,'' he says. "This is not a title fight. I don't have to a doping test but I'm willing to do a test to show you I am clean. I have nothing to hide.''
