What is difference between RT-PCR and Covid test?
Rapid, accurate tests are essential to contain a highly contagious virus like SARS-CoV-2. PCR tests are accurate but can take a long time to produce results. Antigen tests, the other major type of coronavirus test, while much faster, are less accurate.
How much does PCR test cost Singapore?

Is RT-PCR and swab test the same?
Swab and PCR are inseparable test methods to diagnose Covid-19. Swab is a way to obtain examination material (sample). Swab is done on the nasopharynx and / or oropharynx. This collection is done by rubbing the nasopharyngeal cavity and / or oropharynx using a tool such as a special cotton swab.
Is RT-PCR the same as PCR Covid?
What is PCR and how is it different from real time RT–PCR? RT–PCR is a variation of PCR, or polymerase chain reaction. The two techniques use the same process except that RT–PCR has an added step of reverse transcription of RNA to DNA, or RT, to allow for amplification.
What is difference between RT-PCR and rapid PCR?
“Unlike the PCR test, the antigen test can only determine if you have an active virus in your body. The rapid test can't detect small amounts of the virus or asymptomatic cases as accurately as the PCR test can,” Heather said. The rapid test is less accurate and there is a greater chance for a false negative.
What are the steps of RT-PCR?
Traditionally RT-PCR involves two steps: the RT reaction and PCR amplification. RNA is first reverse transcribed into cDNA using a reverse transcriptase as described here, the resulting cDNA is used as templates for subsequent PCR amplification using primers specific for one or more genes.
