If you are planning to travel from India to the United States of America, you need to comply with the pre-travel requirements set by the authorities. One of the primary requirements is to undergo a COVID-19 test and provide proof of a negative result. The Centers for Disease Control and Prevention (CDC) has specified that the only acceptable test for this purpose is the real-time polymerase chain reaction (Rt PCR) test. In this article, we will discuss the basics of the Rt PCR test and its importance in ensuring safe travel during the COVID-19 pandemic.
What is Rt PCR Test?
The Rt PCR test is a diagnostic test that detects the genetic material (RNA) of the SARS-CoV-2 virus, which causes COVID-19. This test is considered the gold standard for COVID-19 detection and is widely used across the world. It is a highly sensitive and specific test that can detect even small amounts of the virus in a sample.
How is the Test performed?
The Rt PCR test requires a nasal or oral swab to collect a sample from the patient. The sample is then sent to a laboratory for analysis. In the laboratory, the RNA from the sample is extracted and converted to DNA using a process called reverse transcription. The DNA is then amplified using a technique called polymerase chain reaction (PCR), which creates millions of copies of the DNA. The amplified DNA is then analyzed to detect the presence of the virus.
Why is Rt PCR Test important for Travel to USA?
The United States has imposed strict travel restrictions to control the spread of COVID-19. According to the current guidelines, all passengers arriving from a foreign country, including India, must provide proof of a negative COVID-19 test result taken no more than three days before the flight's departure. The only acceptable test for this purpose is the Rt PCR test. Passengers who fail to provide the required documentation may be denied boarding.
Where can you get tested in India?
Several government and private laboratories in India offer Rt PCR testing services for COVID-19. Some of the popular options include:
ICMR-approved testing labs
Apollo Diagnostics
SRL Diagnostics
Thyrocare Technologies
Metropolis Healthcare
It is recommended to consult with your healthcare provider or the airline authorities regarding the specific testing requirements and approved laboratories at your departure airport in India.
How long does it take to get the Test results?
The turnaround time for the Rt PCR test results may vary depending on the laboratory and the volume of tests. It may take anywhere from 24 hours to 72 hours to receive the test results. It is advisable to plan your travel accordingly and book your test well in advance to avoid any last-minute delays or cancellations.
Conclusion
The Rt PCR test is an essential tool in the fight against the COVID-19 pandemic. It is also a mandatory requirement for traveling to the United States from India. By taking the necessary precautions and following the guidelines, we can ensure safe and responsible travel during these challenging times.
