Dr. Julia Kryzanowski (kriz-ah-NOW'-skee), deputy medical officer for the health region, says there were some cases of latent TB in the 240 tests.
The university contacted 589 students who share the same classes with a student who fell ill with the infectious disease.
Kryzanowski emphasizes that the latent carriers didn't necessarily catch it from the student.
There is a 10 per cent lifetime risk if the inactive strain is left untreated, although those who carry it are not infectious.
Anyone still wanting to be tested over the next two weeks can make arrangements with TB Control Services.
Students who have left for the holiday break can make alternate arrangements in their own communities.
Symptoms include coughing, fever, night sweats and unexplained weight loss.
"For those students who had a positive test ... they will be assessed for their risk of infection and their risk of developing active tuberculosis disease, and then they will be offered treatment for their latent TB infection," Kryzanowski said Monday.
She added the skin test cannot determine where the infection was picked up.
"We do have students who were not born in Canada, who ... grew up in a country where they have higher incidence rates of tuberculosis, so therefore that student would be expected to have a higher baseline risk of a positive tuberculosis skin test."
