The Mitchell drive-through and Garran walk-in clinics are both still at capacity as of 12pm while the remaining testing clinics are closed due to "unavoidable supply issues", according to ACT Health.
The only two remaining clinics reached their limits early in the morning at 9am and lines had not eased into the day.
The Kambah drive-through clinic and the Nicholls and Holt walk-in clinics are closed.
The Mitchell drive-through and Garran walk-in clinics will remain open. Mitchell is open from 8am to 10pm, and the Garran testing clinic is open between 7.30am and 9pm.
It's advised to try later in the day to get tested.
"Shortages are being experienced across the country whilst demand for COVID-19 testing remains high," ACT Health said.
Canberrans are advised to only get tested if they need to. This includes people with COVID-19 symptoms, or those who have been instructed by ACT Health to get a test.
It also includes anyone at high or moderate risk of being exposed to the virus, such as household contacts or Canberrans who have spent a long time with someone who has tested positive.
Positive rapid antigen tests only need to be confirmed with a PCR test in some circumstances, ACT Health said.
This includes those over the age of 65 years, Aboriginal or Torres Strait Islander people aged over 55 years, anyone 20 weeks or more pregnant; un- or partially-vaccinated people over the age of 16; and anyone identified by a health professional as significantly immunosuppressed.
The Canberra Times has asked ACT Health to outline which supplies are affected.
More to come.
