Two more COVID-19 patients have died in the North, with 103 more cases confirmed since yesterday.
Some 30 patients have now died from the virus in Northern Ireland, with 689 confirmed cases.
It brings the death toll on the island of Ireland to 115, with a total of 4,136 confirmed cases of the virus north and south.
The HSE has carried out up to five times more COVID-19 tests than officials in the North.
It comes as the UK confirmed its worst daily death toll since the crisis began – with 563 more people confirmed dead this afternoon.
Some 2,352 people have now died in the UK since the outbreak began.
- England: 2,137
- Wales: 98
- Scotland: 76
- Northern Ireland: 30
Nearly 30,000 people had tested positive for the virus in England by Tuesday morning – a rise of over 4,000 on the day before.
The UK Government has been criticised for the amount of testing that is being carried out – after it emerged that around 8,000 a day are being administered.
Frontline health staff have warned that they are being forced to self-isolate when needed most because there are no tests available to clear them to return to work.
So far around 2,000 of 500,000 frontline NHS staff have been tested.
Cabinet Office Minister Michael Gove has blamed a shortage in reagents needed for the tests for the low level of testing.
However, the UK Chemical Industries Association has said it is not aware of any shortage.
This afternoon, the Taoiseach Leo Varadkar pointed to the same issue as the reason for the long waiting times for testing in Ireland.
