Fingernail test developed for bone disease

LIMERICK, England, Jul 11, 2005 (United Press International via COMTEX) -- British researchers have devised a way of testing for osteoporosis by scanning a patient's fingernail for the presence of a bone bonding substance.

The substance, disulphide, is found in both fingernails and bones. It helps give bones and nails strength. The researchers, including University of Limerick experts, told the BBC low levels in fingernails indicate low levels in bones.

The test would offer an inexpensive and simple method of determining the need for more detailed tests.

Osteoporosis -- a weakening of one's bones -- affects about one in three women and one in 12 men.

The idea has been nominated for the Medical Futures -- Innovation Awards, due to be announced later this year.
