State health officials plan to test about 250 people for tuberculosis because of a former University of Alabama student who is being treated for the infectious disease.

The agency and the university say they're contacting about 160 people who are now on campus and about 90 more who have left since spring.

The Tuscaloosa News (http://bit.ly/1WPWa9Y ) reports the testing in a precaution for people believed to have had contact with the infected student, who isn't enrolled in classes and is undergoing treatment in another state.

State tuberculosis control director Pam Barrett says people who are on campus in Tuscaloosa will start undergoing blood tests Tuesday.

Anyone who tests positive will get chest X-rays to determine if they have an active case of the pulmonary disease.
