KITCHENER -- Cambridge Memorial Hospital announced on Tuesday evening that it had started offering drive-thru testing at its COVID-19 assessment centre.

The hospital's website notes that testing and assessment are still by appointment only.

According to a post on Twitter, the drive-thru at 215 Holiday Inn Dr. is "ideal if you do not have symptoms." For those with symptoms, the hospital recommends booking an appointment for an assessment and swab.

The drive-thru opens at 10 a.m. every day. It runs until 6 p.m. on weekdays and until 3 p.m. on weekends and holidays.

This is the second drive-thru COVID-19 testing centre that's opened in Waterloo Region since the pandemic began. The other, which is run by Grand River Hospital, originally opened on Glasgow Street in Kitchener before moving to the former Charles Street bus terminal.

There are also a pair of testing centres in Waterloo: one on Bathurst Drive, which is run by St. Mary's General Hospital, and one on Westmount Road North.

The assessment centre usual performs around 250 tests on weekdays and between 130 and 150 on weekends. They hope to increase that capacity with drive-thru testing available.

St. Mary's Hospital's testing centre on Bathurst Drive usually completes 90 to 140 tests each day, and can do up to 200 if needed.

The Grand River Hospital's site does about 400 tests on weekdays and 300 on weekends, but can accommodate up to 800 tests per day.

Same-day appointments are likely available at all sites, by appointment only.

As of Tuesday afternoon, the region's testing partners had completed more than 320,000 tests. That works out to more than 54,000 tests per 100,000 people in the region to date.

The region's online COVID-19 dashboard currently shows a positivity rate of 4.2 per cent.
