8.—(1) For the purposes of these Regulations, where an individual undergoes an approved test or tests consisting only of a polymerase chain reaction test or tests, the individual’s test result is treated as negative for SARS-CoV-2 only if —
(a)
the test result from the sole polymerase chain reaction test the individual undergoes shows no presence of SARS‑CoV‑2 in that individual; or
(b)
the test result from the last polymerase chain reaction test the individual undergoes shows no presence of SARS‑CoV‑2 in that individual, after the individual undergoes further polymerase chain reaction tests and the test results of those tests are uncertain or invalid except the last.
(2) For the purposes of these Regulations, where an individual undergoes an approved test or tests consisting only of an antigen rapid test or tests, the individual’s test result is treated as negative for SARS‑CoV‑2 only if —
(a)
the antigen rapid test result from the sole antigen rapid test the individual undergoes shows no presence of SARS‑CoV‑2 in that individual; or
(b)
the test result from the last antigen rapid test the individual undergoes shows no presence of SARS‑CoV‑2 in that individual, after the individual undergoes not more than 2 antigen rapid tests and the test result of one of them is uncertain or invalid.
(3) For the purposes of these Regulations, where an individual undergoes a series of approved tests consisting of polymerase chain reaction tests and antigen rapid tests, the individual’s test result is treated as negative for SARS‑CoV-2 only if —
(a)
the test results of the first and second antigen rapid tests are each uncertain or invalid, another respiratory specimen from the individual is then subjected to a polymerase chain reaction test, and —
(i)
the test result from that polymerase chain reaction test the individual undergoes shows no presence of SARS‑CoV-2 in that individual; or
(ii)
the test result from the last polymerase chain reaction test the individual undergoes shows no presence of SARS-CoV-2 in that individual, after the individual undergoes further polymerase chain reaction tests and the test results of those tests are uncertain or invalid except the last; or
(b)
the test result of an antigen rapid test shows the presence of SARS‑CoV-2 in that individual, another respiratory specimen from the individual is then subjected to a polymerase chain reaction test, and —
(i)
the test result from that polymerase chain reaction test the individual undergoes shows no presence of SARS‑CoV-2 in that individual; or
(ii)
the test result from the last polymerase chain reaction test the individual undergoes shows no presence of SARS‑CoV-2 in that individual, after the individual undergoes further polymerase chain reaction tests and the test results of those tests are uncertain or invalid except the last.
(4) Despite paragraphs (1), (2) and (3), a result of an antigen rapid test for the presence of SARS‑CoV-2 applied to an individual’s respiratory specimen must be disregarded for the purposes of these Regulations if —
(a)
the relevant sampling activity taking the respiratory specimen from the individual was not carried out in Singapore by or under the direction of an approved test provider; or
(b)
the approved test was not carried out by or under the direction of an approved test provider.
