A quick and inexpensive test for osteoporosis risk

As life expectancy increases worldwide, age-associated diseases such as osteoporosis are having an increasing impact. Although early detection could help physicians intervene as soon as possible -- when treatment might offer the greatest benefit -- this type of detection is not yet possible with current osteoporosis diagnostic tests. Now, researchers have developed a biosensor that could someday help identify those most at risk for osteoporosis using less than a drop of blood.
