The negative Covid-19 test is a new health protocol that every traveller should possess whether he travels for business or pleasure.
The PCR test is considered the golden standard of coronavirus testing, as it possesses very high sensitivity and can detect the virus in a sample—even after levels have dropped below contagious levels.
This is the reason why many countries and airlines require PCR tests in order to be allowed entry.
It helps stop the spread of the virus and can offer peace of mind to travellers going back to their families.
Why Do We Need Covid Testing?
If you’re a business owner, you know how difficult it is to keep track of COVID-19 regulations.
Not only do you have to keep your employees and clients safe, but you also need to be prepared for staff shortages in case of an outbreak.
Being prepared is the only solution to make it work during the coronavirus pandemic.
Covid testing is now a necessity for normal life in the UK, and businesses and health officials are investing heavily in Covid tests (antigen and PCR).
Given the big percentage of unvaccinated people in the country, which threatens herd immunity, the pandemic’s recovery will most likely take a while.
That’s why businesses and health officials in Scotland are counting on PCR testing to help them maintain a safe and healthy working environment.
What Is PCR Testing?
PCR screening for COVID-19 is a molecular diagnostic that looks for genetic information RNA of SARS-CoV-2 in your upper respiratory samples.
Small quantities of RNA from collected samples are amplified into deoxyribonucleic acid (DNA).
They are further duplicated until SARS-CoV-2 is recognisable if present, using the PCR technique.
Since its approval in February 2020, the PCR test in Scotland has been the standard method for detecting COVID-19 because of its high level of accuracy.
Rapid tests like antigen may miss early indications of infection, and that is why they are considered less efective.
How Does The PCR Testing in Scotland Work?
Unlike many other diagnostic procedures, the PCR test in Scotland may detect illness even in the primary stage of infection.
It is effective even when there are not enough infectious coronavirus protein fragments in the sample, or your body hasn’t had enough time to generate an antibody response.
The PCR testing process is comprised of 3 steps:
A swab of your nose is taken by a healthcare expert. A swab is a long, flexible stick with a soft tip that enters your nose.
The swab is then sealed in a tube and shipped to a laboratory after collection for further analysis.
When a laboratory scientist obtains a sample, he or she isolates (extracts) genetic code from the remaining of the sample’s contents.
The PCR stage is subsequently completed with the help of various compounds and enzymes and PCR equipment known as a thermal cycler.
The test tube’s quantity of specified genetic information grows (amplifies) with each heating and cooling cycle.
After several rounds, the test tube contains millions of copies of a tiny piece of the SARS-CoV-2 virus’s genetic code.
If SARS-CoV-2 is present in the sample, one of the compounds in the tube emits a bright light.
The PCR instrument can recognise signal after it has been amplified enough. Scientists read the movement as a positive test result using specific software.
How Long Does PCR Test Result Take?
Although you should obtain your test results as soon as 24 hours after collecting your sample, it may take several days regardless of how long it needs for the collected sample to arrive at the facility.
In Scotland, the PCR test is mostly preferred by travellers and businesses that operate with a large number of people.
What Are The Other Options For COVID Testing in Scotland?
The second option is to secure rapid antigen testing. This is useful for detecting an active COVID infection in asymptomatic individuals.
This method enables organisations to rapidly identify people who are not showing any signs of the disease.
The results are usually available within 15 minutes, making it ideal for business testing.
Fortunately, this type of rapid test is also widely accepted by the Scottish government, making it easier for small businesses to maintain a safe and healthy work environment.
You must have the right tools and protocols to keep your employees and customers safe.
Before making big investments in COVID testing for your business, it is very important to understand how it works.
But even more important is to fallow the protective measures and government advise on how to protect yourself and your employees during this taught times.
As a company, using the PCR test will ensure that your employees are safe and can return to work after isolation.
A PCR-based COVID test provides fast and reliable results, which is essential for your employees’ well-being.
