In a statement, President Lionel Aingimea said this means all tests done on positive and negative samples were all correct.
The President strongly emphasised that no-one on island is positive for the virus.
The positive samples used in the validation testing process were brought in from overseas and contained in a safe enclosure until validation testing for the machines was carried out.
All those samples are harmless and since been removed for the proper testing on crew and quarantine residents which commenced at the weekend.
