Players from Connacht and Ulster came through their second tests a fortnight ago and 153 players and staff from Leinster and Munster have now also passed a second round.
A total of 560 tests have now been conducted across Irish professional players and staff with zero positive tests reported.
The provinces have now all been cleared to enter the next phase of their return to rugby, which includes a graduated return to contact training.
The players and staff will continue to undergo daily medical screening and assessment and will be tested again ahead of the scheduled resumption of the Pro14 next month.
Across the Irish sea, there have been 15 positive cases out of 3,402 tests in the Premiership .
