Many localities and businesses still require a Covid test to ensure absolute safety and protect the health of the community when you travel or work in crowded places.

Therefore, let’s find out with us how long the Covid test is valid and how to use it!

1 What types of Covid tests are there?

Due to the complicated Covid-19 situation, with the emergence of the new variant, which is more contagious and dangerous, you need to be aware of the 3 forms of Covid-19 testing to check your health status if you show symptoms.

Rapid Test (Antigen Testing)

This is a type of direct test that detects antigens of the SARS-CoV-2 virus by collecting samples from nasal or throat secretions, which can be self-tested using rapid test kits available in the market.

Rapid tests are inexpensive and quick, taking only 30 minutes

The strength of this method is its low cost and speed, taking only 15-30 minutes, but it has the disadvantage of not being absolutely accurate, and false positives can occur.

Antibody Test (Serological Testing)

This method checks if a patient is currently or has previously been infected with Covid-19 by testing their blood taken from the fingertip. This is an indirect way of screening for the disease by detecting IgM and IgG antibodies against the Covid-19 virus.

Antibody tests indirectly screen for the disease through blood tests

This method is less accurate than RT-PCR testing because there are cases where the patient’s immune system has not produced antibodies. It also has a similar cost and longer waiting time of 30-60 minutes for results.

RT-PCR Test (Molecular Biology Testing)

RT-PCR or Realtime RT-PCR is a type of direct test that detects the presence of the SARS-CoV-2 virus in the body by collecting nasal or throat secretions.

RT-PCR test is a highly accurate type of Covid test

This method is highly accurate and is commonly used to identify and screen F0 patients quickly and reliably, but it requires high costs, specialized equipment and facilities, and a long waiting time of 4-5 hours for results.

2 How long is the Covid test valid?

Currently, the accepted Covid test results in all provinces and businesses are rapid Covid test results and RT-PCR test results. The validity period depends on the type of test.

The validity period depends on the type of Covid test

  • For rapid Covid test results, the validity period is within 24 hours due to its low sensitivity.
  • For RT-PCR test results, with high sensitivity and accuracy, the validity period is within 72 hours.

3 What is the Covid test used for?

All Covid-19 tests aim to determine whether you are currently infected with Covid-19 or not, and depending on your purpose, you can choose the appropriate testing method to get the correct Covid test result.

Covid test results are required for inter-provincial travel or going abroad

Rapid tests are usually used when people travel between provinces within the country or for work purposes.

On the other hand, highly accurate tests such as RT-PCR tests provide negative results that can be used not only as a pass for domestic travel and work but also for exit purposes.

Frequently asked questions

The validity period of a COVID-19 test result depends on the type of test and the purpose for which it is being used. For diagnostic tests, such as PCR and rapid antigen tests, the results are typically valid for a short period of time, usually within a window of 24 to 72 hours. This is because the viral load in an individual can change rapidly, and the test result only provides a snapshot of a specific point in time. For travel or event entry requirements, it is common for a negative COVID-19 test result to be required no earlier than 72 hours before departure or entry. This timeframe can vary depending on the specific requirements of the country or event organizer, so it is important to check the latest guidelines.

The time limit on COVID-19 test results is due to the dynamic nature of viral infections. An individual’s viral load, which refers to the amount of virus present in their body, can fluctuate over time. This means that a person who tests negative one day may test positive the next day if they are in the early stages of infection. By placing a time limit on test results, it helps to ensure that the information is current and reflective of an individual’s infection status at that specific time.

Several factors can influence the validity and accuracy of a COVID-19 test result. These include the type of test used, the timing of the test in relation to exposure or symptom onset, the quality and proper administration of the test, and the presence of any underlying medical conditions that may impact an individual’s immune response. It is important to follow the instructions provided by healthcare professionals or testing facilities to ensure the most accurate results.

To ensure the validity of your COVID-19 test result, it is important to understand the specific requirements of your intended use. For example, if you are traveling, check the latest guidelines from the relevant authorities to know the accepted types of tests and the timeframe within which the test must be taken. Communicate with your healthcare provider or testing facility about your specific needs, as they can advise you on the appropriate test to take and the timing of your test to ensure its validity.

If your COVID-19 test result expires before you need to use it, you may need to get retested to obtain a valid result. The expiration of a test result is implemented to ensure accuracy and reduce the risk of false negatives or positives. Each testing facility may have its own policies regarding retesting, so it is advisable to contact them directly to understand their specific procedures and requirements for retesting.
