Covid testing singpore is the most precise as well as a reliable way to diagnose a virus with COVID 19 nasal swab PCR. At the time of the test a negative test shows the person as not contracted COVID-19. Having COVID-19 symptoms or being exposed to somebody who tested COVID-19 positive, then the test should be done.

PCR test?

For genetic material such as a virus from a certain organism, a Polymerase Chain Reaction (PCR) test is conducted. The test will detect if a virus occurs when the person is infected. Even when no longer infected, the test may also identify fragments of the virus.

A COVID-19 PCR test?

A COVID-19 PCR test is used to diagnose people currently infected with the coronavirus. The PCR-testation is the golden standard because it is the most exact as well as reliable test. Diagnosing covid testing singpore.

Who should get tested for COVID-19?

  • Symptoms of COVID-19.
  • For 15 minutes or longer, within 6 feet of a person who tested positive for Covid-19.

Working of a covid PCR test

The covid testing singpore PCR test has three main phases:

  1. A swab is used to collect respiratory debris from the nose during sample collection. The long flexible stick of a Swab has a gentle tip in the nose. Nasal swabs as well as nasopharyngeal swabs are two types of nasal swabs that take a sample instantly inside the nasal cavity as well as the nasopharyngeal swabs for collection.
  2. When a laboratory technician gets a sample, they undertake an extraction procedure that isolates genetic material from the sample, including any virus that may be present.
  3. The PCR process uses certain chemicals and a PCR machine known as a thermal cycler, which produces millions of copies of the genetic material for the SARS-CoV-2 virus.

Downsides to a COVID-19 PCR test?

The test can detect very minute amounts of viral material, it can detect SarS-CoV-2 virus fragments even after being recovered from COVID-19. Having had COVID-19 in the past, one may still test positive after covid testing singpore, even if the SARS-CoV-2 virus cannot be transmitted to others.

Finally, the results of covid testing singpore assays should be regarded with caution for the reasons stated. When a real-time RT-PCR negative result is combined with a clinical suspicion for COVID-19, especially when only upper respiratory tract samples were examined.
