Unlike Covid PCR tests that require sending swabs to a specialised laboratory, the rapid tests (also called antigens or lateral flow tests) can return results without being sent to a specialised structure. Some tests provide results even while waiting in less than fifteen minutes. These tests are also known as lateral flow method or fluorescence.

FAQs on Covid Antigen/Lateral Flow Test

What are the symptoms of Covid?

The most common symptoms of COVID-19 are fever, tiredness, and dry cough. Some patients may have aches and pains, nasal congestion, runny nose, sore throat or diarrhoea. These symptoms are usually mild and gradually start. Some people become infected but do not develop any symptoms and do not feel bad. Most people (about 80%) cured of the disease without requiring special care. About 1 in 6 people who contract the COVID-19 became seriously ill and develop difficulty breathing. Older people and those with underlying medical problems such as hypertension, heart problems or diabetes are more likely to develop serious diseases. People with fever, cough and difficulty breathing should seek medical advice.

What is a Covid-19 serological test?

Serological tests can be used by scientists to measure the antibody response of an individual who can help you determine if someone is infected with the virus COVID-19 in the past. These tests might be of interest to an individual if they had not carried out a PCR test when he suffered from symptoms in the past or to determine if someone has had an infection asymptotic. Although many clinics and private laboratories provide serological tests, these are not generally used by the travel or the target locations concerned about the current health of someone and if you have been infected by the virus.

What is the difference between qualitative test, quantitative and semi-quantitative?

In relation to infection by Coronavirus, a qualitative test determines the "if" while quantitative tests and semi-quantitative answer to the question "what?" By measuring the level of SARS-CoV-2 antibodies in a patient's blood sample, the quantitative tests and semi-quantitative give a more definitive answer on the body's immune response to the virus.
