Overseas Travel: PCR Tests Are Here To Stay For The Foreseeable Future


Travellers are facing more restrictions nowadays due to the outbreak of Covid-19. There are new rules regarding when and where they can go and what documents are needed in order to be allowed entry.

When travelling abroad, they need to find an authorised lab and get tested; otherwise, they risk being denied boarding as most airlines will require travellers to show a negative Covid-19 test when they check-in for a flight. 

Whether travelling to or from the UK, you’ll need to present a negative test to get the boarding pass.

If you can’t make it to the clinic, you can take a self-test at home. Just make sure you follow all of the guidelines and don’t try to use an over-the-counter test.

You can get a PCR test in Edinburgh or any other big city in the UK at a testing facility, laboratory or inside the airport.

The PCR technology is considered the most reliable and widely accepted way to get tested for COVID-19.

Why You Should Get Tested For Covid-19?

In today’s circumstances, testing is essential for limiting and controlling the COVID-19 outbreak.

This can be done by diagnosing affected individuals and preventing the spread of COVID-19 from person to person.

Understanding who has been infected is particularly vital since people who have COVID-19 immunity need to operate safely in critical areas like medical services, community security, and the hospitality and travel industry.

Some of the tests are more sensitive than others. If you’re traveling abroad, consider using the PCR test if it’s available when you’re traveling.

How Is The PCR Test Performed?

A PCR test involves three key phases. Each stage happens at various temperatures: 

1. Denaturation

When the double DNA is heated to 94 degrees Celsius (201.2 degrees Fahrenheit), it melts and splits into two strands of single-stranded DNA.

2. Annealing

The primers couple up with the single-stranded “template” (the template is the segment of DNA to be replicated) at average temperatures, approximately 54 degrees Celsius (129.2 Fahrenheit).

The enzyme connects to the small fundamental measure of double-stranded DNA (the combined primer and template) and duplicates the template.

3. Extension

The enzyme operates best around 72 degrees Celsius (161.6 degrees Fahrenheit), and DNA basic principles corresponding to the template are attached to the primer, resulting in a double-stranded DNA coenzyme.

How To Protect Yourself

It’s important to remember that just because you’ve been vaccinated or had a recent negative test result doesn’t imply you’re safe and can travel anywhere.

To help prevent the spread of COVID-19, follow these 3 basic steps:

1. Stay in The House and Observe Your Health. 

Avoid contact with others, particularly those at a higher risk of getting ill, such as adults and those with medical conditions.

If you’ve had contact with somebody who has COVID-19, stay in the house and get a Covid test if you start developing symptoms.

2. Consider the Persons You’ve Lately Encountered. 

If you’ve been diagnosed with COVID-19, a public health professional may contact you to enquire about your health, discuss who you’ve been around, and enquire about where you spent time when you may have spread the virus to others.

3. Take the Medical Department’s Call. 

Interactions with medical department personnel are kept private. This ensures that your medical and personal data will be kept secure and discussed only with your health professional.

COVID-19 testing is the only way to determine if you are infected with the coronavirus and stop any further transmission.

It is important to get tested in order to protect your family and those with whom you come into contact. Tests such as the PCR test can effectively detect and diagnose the virus. 

What If You Get A Positive Result?

People should undergo a PCR test if they are experiencing symptoms. Vaccination is a precaution and should not be perceived as panacea.

Given different variants and mutations it is hard to tell haw effective is the vaccine against this constantly evolving virus.

It is important to self-isolate yourself in case the result comes positive, as this is the only way to protect others.

If you do get infected, you should seek medical attention. If you have mild symptoms, you can treat the illness at home. 

Symptoms of COVID-19 virus infections may appear two to fourteen days after an exposure.

So it is important to remember that even if you do not exhibit any symptoms, you still can be infectious and transmit the virus to others. 


If you are planning on travelling and do require a Covid-19 test for this purpose, it is recommended that you book a PCR test in advance and make sure to follow the most updated regulations on travel during Covid-19.

Whether you’re travelling to another country for business or pleasure, you’ll be glad you took the precaution.
