Covid-19 PCR Swab Test, Antigen test & Antibody Testing


Global Travel Clinics offers both Covid 19 PCR Swab testing as well as Covid 19 Antibody Testing at many of our locations. 

The Global Travel Clinics COVID-19 Test kit uses Polymerase Chain Reaction (PCR) technology.

A PCR test is designed to detect individuals with a dynamic infection i.e., those presently infected with SARS-COV-2, the virus that causes COVID-19. It diagnoses RNA particles of the virus which is the genetic material, currently present in an individual. It is unlike antibody-based test which detects the presence of antibodies produced by the body’s immune system in response to the virus that indicates previous infection.

It is worth noticing that PCR swab/antigen tests can be very labour intensive, with various phases at which errors may take place between sampling and examination. False negatives can occur up to 30% of the time with different PCR tests, meaning they are more useful for confirming the presence of an infection than giving a patient the all-clear.

The sampling process of the Covid-19 PCR testing at Global Travel Clinics is simple and takes just a few minutes. The test result are as quick as within 8 to 24hrs.

Covid Antigen tests also detects whether virus is present in the body or not but are less accurate than Covid PCR tests. 

Covid Antibody Tests are designed to indicate if there is a current exposure to Covid 19 virus or there has been a past exposure to Covid 19.  

Currently most of the countries require a Covid PCR test to be taken 48, 72 or 96 hours before departure and proof of negative PCR result certificate must be presented before people are allowed to board the flight. Only few countries including USA are also accepting Negative Covid Antigen test to facilitate entry in to the country. The requirements for countries are changing very frequently so please check carefully from official channels what kind of COVID test is accepted by your airline and border control of your intended destination.

FAQ for COVID 19 PCR Gold Standard Swab test


The majority of tests used to diagnose Covid 19 are genetic tests known as PCR tests. These tests are very accurate because even if there’s a tiny amount of virus is present in the patient sample, PCR (polymerase chain reaction) is able to take genetic material from the virus. It targets specific gene segments, that only this virus has and makes very large number of copies of that segments so that they can be detected and measured. Using this method, a PCR test can tell you if you have Covid 19 at the moment, but not if you had it in the past. Initially it took several days to get the results of PCR-based corona virus testing but now as the virus has vamped, rapid PCR tests have been approved that give results in 24hrs-48hrs.

You must stay at home for seven days from the day your symptoms begin. If your temperature goes on for longer than seven days, you should keep yourself quarantined till you get symptom free for 48 hours.

Corporates should inform their manager of the positive test and any additional advice given by NX Healthcare. Everybody in your household should remain self-isolated for 14 days from when your symptoms started. If they start to show symptoms, they will have to continue self isolating for 7 days from onset of symptoms.

If you do not feel well enough, you will feel the following symptoms

  • Temperature more than 37.8°C if checked with a thermometer, or sweats/shivers and similar symptoms
  • Regular and persistent cough (with or without sputum), gruffness, nasal release or congestion, breath shortness, sore throat, gasping, sneezing
  • Loss of smell with or without headache

Symptoms, especially the cough, can persist for several weeks; however, the cough does not stop you from going back to work. If anyone has alarms about an ongoing cough, they should contact their GP as soon as possible.

There is no age limit. If the swab fits in the nose, it can be used as instructed.

  • Adults aged 18 and over
  • Teenagers aged 12 to 17
  • Children 11 and under

It involves taking a swab from the nose and the throat. It’s very simple.

It totally depends on how strong your immune system is. Although the Covid-19 PCR test is most likely to diagnose the virus earlier on, there are a lot of individuals who still carry virus well into the second or even third week. 

The test is only for viruses and not antibodies so it will not reveal whether you have previously had the virus or not.

Positive analytical result is the possibility that the person most likely has the infection. Pre-test probability has the highest effect on false-positive rates. As the pre-test probability test rises, the false-positive rate decreases and the positive predictive value increases.

Negative analytical result is the possibility that the individual who has a negative test result most likely does not have the virus. Pre-test probability and test sensitivity have the highest effect on false-negative scales. As the pre-test probability decreases, the false-negative rate decreases and the negative predictive value increases.

A Ct Scan does not specify how much virus is present in an individual, but only whether or not viral genetic material was detected at a definite threshold. PCR tests can either be qualitative or quantitative, and this affects how a Ct value is interpreted.

Your travel certificate is a certified document of when you had your PCR swab test and the result. Its validity does not expire but most airlines and destinations need you to have your test taken within a definite timeframe. Therefore, you need to make sure your test is taken within the required timeframe.

Firstly, please make sure that you and your household get yourselves isolated according to guidelines provided by the government. The PCR test will detect viral RNA from your nose and throat. The probability of detecting virus is highest in the initial days of symptoms. Ideally, the sample should be taken from symptomatic persons between day 1-5 from symptom onset. However, there are various cases when the virus can be detected later into the illness. A negative test result is important to tell you that there is no virus present on that swab.

Yes, It happens because either the test did not detect the virus earlier or because you were infected after the test was done.

There is no proof to recommend the COVID-19 diagnostic test causes any side effects.

You will need to provide your passport number. It will appear on your travel certificate.
