Different Methods of Rapid Covid Testing

There are several methods used for covid testing. Although some of them are considered more authentic than others, every method is valid and gives accurate results. All the different testing methods are divided into two main categories mentioned below.

Viral Tests

Viral tests detect the presence of the virus (Sars-CoV-2) that causes Covid-19. The samples used for viral testing are taken from the nose or mouth of a person. They are further grouped into two kinds;

  • Laboratory tests

Laboratory tests take up days to give the results. Usually, they give authentic results, but some tests may require further tests for confirmation too. The RT-PCR (Reverse transcription Polymerase Chain Reaction) and several other types of NAATs fall under the laboratory testing category.

  • Rapid tests

These tests do not require much time. They can be finished within minutes, and people can get the results right then. The different tests types of rapid tests include Antigen tests and some NAATs.

  • Antibody Tests

This test detects the presence of antibodies (the proteins that the immune system of a human body develops in order to fight off infections and protect the body from the same disease in the future) in a person’s blood.

Antibody tests are not to meant to diagnose a current infection or disease; they help learn the immunity system and only tell whether the person has been affected by the virus in the past or not. Therefore, they are not recommended if a person is currently suffering due to Covid-19.

PCR Covid Testing

The PCR (Polymerase Chain Reaction) Covid test is a molecular test that is a type of laboratory examination and falls under the category of viral tests. It is one of the most accurate and reliable methods of Covid testing. It basically detects the presence of Ribonucleic Acid (RNA) and of SARS-CoV-2 (the virus that causes Covid-19) in the sample taken from your upper respiratory tract. In order to understand the whole procedure of PCR testing, keep reading.

The Procedure of PCR Covid Testing

There are a few steps that explain the proper method of this test.

  • Sample collection

The process starts when a healthcare professional collects respiratory material as a sample from your nose. They do it with the help of a swab, which is a flexible stick sent down your nose or even further. It depends on what kind of swab the healthcare provider uses. If they use a nasal swab, it will immediately collect the sample from your nose. However, if they choose to use a nasopharyngeal swab, that would require going further into your nasal cavity to collect the sample for the test. Whatever type of swab is used, the test can be performed alright with it. Once the sample is collected, the swab is covered with a tube and sent to a laboratory to continue the procedure further.

  • Extraction

When the collected sample is handed over to a laboratory member, they proceed to extract genetic material from the rest of the content present in it.

  • Amplification of genetic material

This final step requires the use of several tools like some particular chemicals, enzymes, and a thermal cycler (the PCR machine). Here, the extracted genetic material passes through a number of heating and cooling cycles first. These cycles are supposed to amplify (increase) the amount of genetic material in the test tube. As a result of which, several million clones of the genetic material of SARS-CoV-2 can be found in the tube.

From the many chemicals present in the tube, one develops a fluorescent light and signals the presence of SARS-CoV-2 in the sample. The PCR machine then detects the signal after enough amplification of the virus's genetic material. Healthcare professionals then verify the test result as positive with the help of software. The test being positive means that the SARS-CoV-2 is present in the sample.

The test results of this testing procedure take a day at least. Sometimes, the result comes out within a day too, but usually, it takes more than that. However, it may take more time but will always give you authentic and reliable results that need no confirmatory tests.

The PCR Covid test Houston gives an accurate result because it detects even the most minute bit of virus material if present. It concludes the fact that this test can signal the presence of SARS-CoV-2 even after you have fully recovered from the virus. And sometimes, that can cause a problem too. You may have recovered and cannot spread the virus around, but if you are hinted Covid-positive, you need to consult a healthcare professional and discuss that with him.


RT-PCR Covid Testing

This testing method is almost as same as the PCR method. The only difference between both is an addition of ‘Reverse Transcription Step’ in the RT-PCR procedure. A special type of enzyme called ‘Reverse Transcriptase Enzyme’ is used to carry out this additional step and bring the result of the test.

The time frame that the RT-PCR Covid test result requires ranges from 1-3 days.  Apart from all this, both the methods are identical and provide equally accurate results.
