Biosignia Inc. has introduced the Know Your Number service.

The service gathers blood test information and other information about employees, then produces a report estimating how likely the employees are to develop conditions, such as diabetes and stroke, according to Biosignia, Research Triangle Park, N.C.

Employees who are at risk of developing serious health problems can use the results to change their behavior in ways that might help them improve their odds, Biosignia says.
