Mobile phone STD test - killer app or fantasy?
People will soon be able to tell if they have an STD by urinating on a small computer chip and inserting it into a mobile phone or computer, doctors and scientists in Britain claim.
But Australia's foremost sexual health expert is sceptical about the idea, saying it may be a long time before such a product is consumer-ready.
The small devices, similar to pregnancy testing kits, will reportedly be able to give people a home diagnosis within minutes. Millions of pounds have been poured into the project to combat an STD epidemic in Britain, where infections reached a record 482,696 last year.
"Your mobile phone can be your mobile doctor. It diagnoses whether you've got one of a range of STIs, such as chlamydia or gonorrhea and tells you where to go next to get treatment," Dr Tariq Sadiq, the sexual health expert from the University of London who is leading the project, told The Guardian.
Sadiq said young people especially were embarrassed to see their doctor about STDs, which was making the situation worse.
Mobile phones are increasingly being used for health purposes, such as the remote monitoring of elderly people.
The Guardian reported that the developers of the rapid testing devices - which include experts in microbiology and phone operators like O2 - expected them to be sold for a pound each in vending machines in nightclubs, pharmacies and supermarkets.
The research has been given the thumbs up by Professor Noel Gill, the head of HIV and STIs at the British government's Health Protection Agency, who said he hoped the application of new technology would reduce infections among young people. The HPA would coordinate large-scale evaluations of the technology within a network of collaborating STI clinics.
But Professor Basil Donovan, head of the sexual health program at the University of New South Wales' National Centre in HIV Epidemiology & Clinical Research, said he maintained a "healthy scepticism" about the project.
"If they say that's what they're aspiring to that would be terrific, but unfortunately there's no such test yet - at this stage it's just fantasy," Professor Donovan said in a phone interview.
"There was a paper published just a couple of weeks ago where they looked at all of the commercially available home testing kits for chlamydia and they were just a joke - if someone had chlamydia there was only a 10 per cent chance that the test would show it up."
But Professor Donovan said he believed it was a "great idea", concurring with Dr Sadiq that a big problem with current STD testing was that "it's too embarrassing and too expensive to test everyone all the time".
"I think in our lifetime it will happen and at the moment there are rapid home tests available for some conditions like HIV that are actually quite good," he said.
Professor Adrian Mindel, sexual health medicine expert at the University of Sydney and the director of the sexually transmitted infections research centre at Westmead Hospital, said the STD problem could not be solved with technology alone.
"I don't think the issue is the rapid test, it's getting people to do the test that is the issue and that to me is the fundamental barrier rather than the technology," he said.
"People have to identify themselves as being at risk and that is the difficulty at the moment."
Professor Mindel said it was critical to educate young people about STDs, including that the majority of the infections don't have symptoms and the infection may be transmitted even when symptoms aren't present.
