MADRID, Spain (CNN) -- The parents of Madeleine McCann said they're not afraid of DNA tests that press reports have said could link them to their daughter's disappearance.
Madeleine McCann has been missing since early May when she vanished in Portugal.
"There is nothing in those DNA tests related to Kate and I that will show anything other than completely innocent," said Madeleine's father Gerry McCann in an interview with Span's Antena 3 television. "Whether that is enough to eliminate us I don't know, but we will be eliminated. I'm confident of that, because we have done nothing."
They were speaking in their first TV interview since being named suspects in the case in early September.
Although Portuguese officials have not commented publicly on evidence or interviews in the case, authorities reportedly found Madeleine's blood in a car the family rented 25 days after reporting her disappearance. Portuguese TV station SIC, citing police sources, reported that DNA matches to the girl were found in the car.
Portuguese police won't release details of the case, citing the ongoing investigation, and CNN has been unable to independently confirm the information.
The parents, both doctors, returned to their home in Rothley, England, in early September.
Madeleine's parents have said she disappeared from their hotel room in a vacation resort in Portugal's Algarve region on May 3 while they dined in a restaurant nearby.
They deny they had anything to do with their daughter's disappearance.
The McCanns' spokesman, Clarence Mitchell, told CNN the couple did the Antena 3 interview on the advice of private investigators, who have started a new multilingual hotline in Spain. It's part of a renewed effort to find Madeleine, focusing on Spain, Portugal and Morocco.
Her parents scoffed at published reports suggesting they may have sedated their daughter and her twin younger siblings.
"There is absolutely no suggestion that Madeleine or the children were drugged," Gerry McCann said. "And it's outrageous."
"All I'm going to say is, I'm Madeleine's mummy," said Kate McCann. "I know she was taken from that apartment and she's out there and I want her back. That is all.
"Everything else, I'm sorry, is rubbish."
The search for Madeleine has sparked worldwide attention. Richard Branson, chairman of Virgin Group, pledged $200,000 to help the British couple find their young daughter to help clear their name. Soccer star David Beckham offered to raise money for the search. The parents have even met with Pope Benedict XVI in Rome.
But as their search continues, life is not the same, the McCanns said.
"I feel sad, and I feel lonely and life certainly's not as happy without Madeleine," said Kate McCann. "But you know, I still have hope, we still have hope." E-mail to a friend
