What is
PCR?

PCR is one of the most important scientific advances of the 20th century

Polymerase chain reaction (PCR) is an efficient and cost-effective way to copy small specific DNA or RNA sequences.

Plants and animals, bacteria and viruses—every organism has its own unique nucleic acid sequences. Using PCR, millions of copies of fragments within these sequences can be made in a short amount of time. It is an innovative yet simple method that serves as an invaluable tool in the field of molecular diagnostics.

Even with minimal amounts of sample, PCR enables reliable diagnosis and monitoring of diseases, providing high sensitivity that may not be possible with other diagnostic methods, like culture or serology. The accuracy, precision, and reliability of PCR are among the reasons it is considered the “gold standard” by many in the diagnostic community.

Real-world applications of the “DNA photocopier”2-6

From diagnostics, research, and prenatal care to agriculture and forensics, PCR techniques are an essential element in the arsenal of today’s scientists.

PCR is most commonly used in diagnosing infections like influenza, COVID-19, Human Immunodeficiency Virus (HIV), Chlamydia trachomatis, and viral hepatitis among others. It has also helped to revolutionize cervical cancer screening, and plays a critical role in ensuring the blood supply stays safe.

Beyond an initial diagnosis, PCR is also used to make personalized healthcare possible.

  • For instance, measuring a person’s viral load (the amount of virus present in a person’s body) allows healthcare professionals to gauge how well a medicine or treatment is working. This is an essential part of managing certain chronic infections, such as HIV or hepatitis B
  • PCR can also play a role in liquid biopsy testing (a simple and non-invasive alternative to surgical biopsies) to identify the presence of specific gene mutations (e.g. EGFR and KRAS) in cancers (e.g. lung and colorectal cancer).

The high sensitivity and broad-spectrum application of PCR make it a leading choice in molecular laboratories. However, there are other important complementary technologies, like next-generation sequencing, that have the potential to unlock new information about the role of nucleic acids in disease.

Safety measure to follow in public if you develop symptoms

If you are experiencing Covid-19 symptoms, you should follow safety measures until you undergo a PCR test and treat the symptoms according to the test results.

Self-isolation is a must to stop spreading the virus to other people. Limit yourself to unnecessary contact if you have trouble breathing.

Practice social distance by staying in a specific room and avoid going outside. Make sure you don’t come in contact with animals as well. 

Wear a facemask when you are around other people while visiting the medical center. Cover your cough and sneezes with tissues and dispose of them in a lined trash can.

Clean your hands more often with an alcohol-based sanitizer or with soap and water. Avoid touching your eyes, nose, and mouth if you are outside and if you did not wash your hands. Use soap and water, preferably to wash your hands.

All high-traffic surfaces around you in your home should be cleaner with spray sanitizer frequently. High-traffic surfaces such as toilets, phones, tablets, tables, tabletops, doorknobs, and counters can spread the virus as it comes in contact with many people frequently. 

Avoid sharing personal household items with your family members, and make sure to clean them as soon as you use them.

When should you get a Covid-19 test?

It is necessary to get a negative Covid-19 PCR test certificate before traveling abroad by air. Major countries of the world will not permit you to enter without a negative Covid-19 result.

RT PCR test is advisable if symptoms such as fever, cough, and difficulty in breathing last for more than the usual period of common cold and fever. Some of the other health issues which are a common symptom of Covid-19 are sore throat, fatigue, mucous formation, running nose, muscle pain, loss of taste or loss of smell. If you experience these symptoms and fever and cough, you should isolate yourself and get an RT PCR test as soon as possible. 

You must also get a PCR test after exposure to a Covid-19 positive patient. Once you get the test, you will be able to follow medication according to the PCR swab test result

Benefits of RT PCR test

RT PCR test is the most effective testing method widely used by hospitals and laboratories to detect the Covid-19 virus. It has the edge over other forms of Covid-19 testing because of its various advantages.

  • It is a highly efficient procedure with great precision with increased sensitivity and specificity.
  • The medical staff is well acquainted with the robust technique of the RT PCR test.
  • We process a considerable number of samples together.
  • The chances of getting a false positive or a false negative result are minimum through an RT PCR test.
  • It has become the gold standard for detecting Covid-19 viruses. 
  • The process of collecting a swab sample for the test is minimally invasive.

The scenario of international travel has completely changed since the Covid-19 pandemic began. Countries have imposed strict safety for arrival and departures. Getting a PCR test for travel purposes is a mandatory requirement for traveling by air. 

Get a PCR test for traveling abroad from our laboratory in Seychelles as you need a negative PCR test result to enter any country. We issue acceptable results by Seychelles authorities for PCR testing and ANTIGEN testing. With our results, you can get a “Fit to travel” certificate that will be accepted everywhere.

Everyone traveling from Seychelles, including infants and children, must have a negative COVID-19 PCR test certificate from an accredited laboratory such as ours, regardless of vaccination status. Samples should be taken of the PCR test within 72 hours before arrival and departure. 

Don’t worry about visiting our laboratory for testing, as we will visit the hotels you are staying in to collect the required sample. 

Private PCR test process & ANTIGEN test

We provide the PCR test as well as the ANTIGEN test at our fully licensed laboratory in Seychelles. In case of an RT PCR home test, our officials will come to your home to perform the test. We maintain the highest standards  for collecting, storing and testing samples to ensure the accuracy of every test we perform in our lab. 

We take the sample of your nasal or throat swab back to our laboratory. In the laboratory, we check for coronavirus RNA present in the swab; if it is present, then we convert into DNA. We produce many copies of the viral DNA so that we can use it to produce a measurable result.

An RT PCR test is the most accurate test, which helps deliver accurate results. The accuracy of the test also depends on factors such as the collection and maintenance of the sample and during which stage of illness did we perform the test. 

We follow the best practices of collecting and storing the sample at our laboratory to deliver accurate and quick PCR test results. The ANTIGEN test service is also available in our laboratory at Seychelles Medical. 

Get the result of your PCR test in 24 hours.

Covid-19 infection rate is on the rise since the beginning of the pandemic. Countries all over the world follow safety measures to control the spread of the virus. The importance of testing and isolating has been acknowledged by all governments worldwide. 

A PCR test is the ideal test to detect the Covid-19 virus. At Seychelles Medical, we provide the service of RT PCR (reverse-transcription PCR) testing. This is the most reliable test, as it has the ability to detect even a single virus particle from the swabs taken from the nose or mouth. 

We have a fully licensed laboratory with international accreditations for Covid-19 testing in Seychelles. The RT PCR test result will be available in 24 hours after collecting the swab sample from your nose or mouth.
