Healthy Living: Smartphones and Your Health

Almost seven-billion of us use one.

Tonight in Healthy Living, researchers say that the phone you talk, text, and tweet with could one day do much more for your health.  
Researchers at UCLA created various attachments that fit on smart phones. One can perform an HIV screening. 
Another detects allergens in food. A special tube measures allergens optically with the phone's camera. Other attachments measure the presence of E-coli in food, blood cell counts, and blood sugar levels.
Cell phones are less expensive than a large lab and can be used in the field with immediate results. 

They're not on the market yet, but once they are available researchers believe it will be particularly beneficial to doctors and patients in developing countries who don't have access to advanced laboratories.
