MADISON, WI (WTAQ) - A company that makes medical devices plans to close a factory in Madison by the fall of 2014.

Hologic Incorporated of Bedford Massachusetts told state officials about the shutdown Wednesday – the same day it completed a nearly $4 billion acquisition of GenProbe. That company makes diagnostic tests.

About 130 jobs would be eliminated in the closing of Hologic’s Madison plant.

Layoffs are scheduled to begin at the end of September, and continue for another two years.
