The University of Regina announced today that nearly 270 people may have been exposed to someone else's blood.
The improper blood tests were conducted between 2006 and 2012. They were done on students, research participants, and on clients of the department. The tests measured a person's blood lactate levels.
The university's kinesiology department admits it's guilty of using improper blood testing procedures.
Harold Riemer, Dean of Kinesiology and Health Studies, said each time a new person was tested, the needle was replaced. However, the holder was only swabbed down with alcohol and then used again.
Riemer said that used to be a standard practice, but it isn't anymore.
"As long as I'm dean here, we will put practises in place to make sure we are reviewing what we are doing in our labs on a regular basis that could endanger students," Riemer said. "We have an obligation to do that."
The university stopped using the multi-use devices in January after the First Nations University of Canada in Prince Albert was found to be using outdated protocols.
Maurice Hennick with the Regina Qu'Appelle Health Region said it's unlikely someone has been exposed to a blood disease such as HIV or hepatitis.
"We are at far more risk of encountering a lightning strike or even being run over by a motor vehicle than encountering a scenario such as this," Hennick said.
Some students, including Matt Taylor, are still skeptical.
"You'd expect them to follow proper procedures and ensure that things are sanitary," Taylor said. "But as far as releasing the statement, at least they're taking responsibility for it. They're not hiding."
Since the university didn't keep the name of the participants, it's sending out letters to a possible 645 people who may have been affected.
It's asking anyone with concerns to go see their family doctor.
