Swiss army device?

Researchers at Harvard University have developed a handheld device aimed at people living in poor regions. 

The device can:
- monitor diabetes
- detect malaria
- analyse drinking water
- test water for metals e.g. lead and zinc
- look at sodium levels in urine
- search for malaria antigens in blood samples
- send information to a computer to anywhere in the world using a mobile phone

The device is being tested in India and was developed to resemble glucose monitoring units which are used widely and are recognised by many healthcare professionals.

The device weighs around 57grams and costs around $25 and has been reported as simple to use.
