Answer:
Explanation:
The polymerase chain reaction is a routine laboratory technique used to amplify small samples of DNA into larger quantities that can be detected and analysed. For patient diagnosis, a viral RNA or DNA sample is taken by swab or blood draw, before being sent to a specialist laboratory for analysis.
For RNA viruses, such as SARS-CoV-2, the polymerase chain reaction is preceded by an additional step to produce a complementary DNA template (cDNA) from RNA,
by the addition of a reverse transcriptase enzyme (hence, Reverse Transcription-PCR (RT-PCR)).
PCR then begins by the addition of short DNA sequences known as primers, which bind the viral DNA strands. The double-stranded section of DNA is then recognised and bound by a thermostable polymerase enzyme which acts as a molecular photocopier to extend the sequence and produce a full, complementary strand.
Answer:
Depending on the situation, the doctor may recommend a molecular test to confirm the negative result of the antigen test.
