CALGARY -- Alberta Health Services says many of its laboratory collection sites remain closed after others opened in mid-June.

Lab services at North Hill Centre, Bankview, Glenmore Landing and Gulf Canada Square remain closed and AHS says it has implemented major changes to a number of labs that opened on June 16.

AHS has implemented patient screening, physical distancing, use of PPE and masks and a reduction of walk-in options in favour of pre-booked appointments.

“We recognize that these are difficult, stressful times, and the healthcare changes resulting from the pandemic have been challenging for patients,” AHS said in a statement.

“Our number one priority remains to protect the health of Albertans as we continue to provide safe, efficient lab services."
