Daily testing numbers peaked at 63,600 on December 21 and have declined since then.
“NSW Health continues to be concerned by low rates of testing,” the agency said in a statement released on Tuesday.
“We urge people across the state to come forward for testing with even the mildest of symptoms that could signal COVID-19,such as a runny nose or scratchy throat.
“High testing rates play an important role in helping to contain the spread of the disease,as it gives us the best chance of finding new cases and preventing new chains of transmission from becoming established.”
Testing has fallen across all local government areas in Sydney in recent weeks,with the lowest weekend figures recorded in Burwood,where 25 tests were conducted on Saturday and Sunday,followed by Hunters Hill,with 58 tests.
Northern Beaches continues to have the highest testing numbers,with 768 tests conducted over the weekend.
