Travelers Plans How to Travelers Plans in The World
With the ongoing pandemic, the requirement of a negative COVID-19 test report has become mandatory while traveling. The most commonly used test methods are RT-PCR and PCR tests. Both are molecular tests and detect the presence of the virus in the body. However, there are some differences between the two tests. This article will discuss the differences between RT-PCR and PCR tests and which one to choose for traveling.
What is RT-PCR?
RT-PCR stands for Reverse Transcription Polymerase Chain Reaction. This test is considered the gold standard for COVID-19 diagnosis. This test detects the presence of the virus’s genetic material in the body. In this test, a nasal or throat swab is collected from the patient, and the genetic material of the virus is extracted. Then, the genetic material is reverse transcribed into complementary DNA, and the PCR amplification is performed. The amplified DNA is then analyzed to determine the presence of the virus in the sample.
What is PCR?
PCR stands for Polymerase Chain Reaction. This test is also used to detect the presence of the virus in the body. In this test, a nasal or throat swab is collected from the patient, and the genetic material of the virus is extracted. Then, the PCR amplification is performed to amplify the viral genetic material. The amplified genetic material is then analyzed to determine the presence of the virus in the sample.
What are the Differences Between RT-PCR and PCR Tests?
The main difference between RT-PCR and PCR tests is the step of reverse transcription. In RT-PCR, the viral RNA is reverse transcribed into complementary DNA, which is then amplified. In PCR, the viral RNA is directly amplified. Another difference is the sensitivity of the tests. RT-PCR is more sensitive than PCR, and it can detect the virus even in low levels. PCR is less sensitive than RT-PCR and may not detect the virus in low levels.
Which Test Should You Choose for Travel?
The choice of test depends on the travel requirements. Some countries require an RT-PCR test report, while others accept PCR test reports. It is important to check the travel requirements before booking the test. However, if there are no specific requirements, it is advisable to choose an RT-PCR test as it is more sensitive than PCR and can detect the virus even in low levels.
