Negative: this means the virus could not be found on your swab.

Unclear/Inconclusive: it is not possible to say if you had the virus when the test was done. Unclear/inconclusive results are very rare, they can be caused by a number of factors usually relating to inadequate sampling (for example the laboratory could not detect human DNA on the swab) or a swab sample is provided with excessive mucoid material present which will interfere with the correct operation of a lateral flow test.

Re-swabbing and providing a second sample is recommended if an unclear/inconclusive result is reported initially.

Positive: this means the virus was found on your swab.
