Frequently asked questions

What is the (SARS-CoV-2) Virus

Coronavirus is an infectious disease caused by a newly discovered (SARS-CoV-2). There is an unprecedented research program underway to understand what we are dealing with, unfortunately information is changing frequently. The virus spreads primarily through droplets of saliva or discharge from the nose through coughing and sneezing.



What is an Antigen?

An Antigen (Ag) is a toxin which induces an immune response in the body, especially the production of antibodies



What is an Antibody?

An Antibody (Ab) is produced by the body as a response to fight off infection and protect against disease (i.e. the antigen)
These are produced in a sequential series, with IgA being the first immune response, IgM being the main response for tackling the virus and IgG remaining in the body for a prolonged period of time



What is the difference between an Antigen Test and an Antibody Test?

People can experience a range of symptoms and some people can be infected without experiencing any symptoms at all.
People also produce their antibodies at different times and the level of antibodies may be relative to the severity of the symptoms.
A Professional Antigen test will tell you whether you currently have the disease.
A Professional Antibody test will tell you whether you have already had the disease and have recovered



What is an Antibody Test?

It is a test that can tell whether someone has had COVID-19 by detecting the specific antibodies to the virus.

It measures IgG and IgA antibodies against SARS-CoV-2, that causes the Virus



Why Should I get an antibody test

You could have SARS-CoV-2 and not know it.
It will also tell you if you have had the covid virus and not the flu, the common cold or other pulmonary infections.

Antibody tests can give health officials a better idea of how common the virus is.It also helps to provide data and information for control of the virus and helps scientists understand the virus better



How does the antibody test work?

The BioSURE COVID-19 Antibody Cassette Test is a qualitative, rapid, lateral flow immunoassay for detection of IgA, IgG and IgM antibodies to SARS-CoV-2 in human blood, serum or plasma, as an aid to diagnosis of active or recent COVID-19 infection in symptomatic or asymptomatic individuals.
Test results should be considered in conjunction with other test results and clinical information.
The test can detect 3 types of antibodies: IgA, IgG and IgM.
Levels of these antibodies develop and decline at different rates within different individuals.
This test may not detect the most recent COVID-19 infections.
You can test for antibodies from as little as 7 days after the onset of symptoms, but if the result is negative this does not mean that the customer being tested has not been infected – they should use caution and test again in 7 days. N.B. As COVID-19 is a new infection this is subject to change as research into the virus continues.



When should I take the test?

It is important to wait 14 days from the onset of symptoms before taking this test.

This is to ensure that antibody levels are detectable.

If you did not experience any symptoms but were exposed to the virus this test should be taken 21 days after the last exposure.

This ensures the accuracy of the test (98.2%).



Who is this test not suitable for?

It should be noted that the test may not accurately detect antibodies in those with a compromised immune system as their production of antibodies is weakened or slower.

This may affect individuals with immunodeficiency disease such as HIV or those taking medications that suppress the immune system.



Does this test tell me that I currently have the Virus?

No, this test detects antibodies; these are produced some time after an individual becomes infected.

In the majority of people antibodies reach detectable levels 14 days after the development of symptoms or, if you haven’t had symptoms, 21 days from possible exposure to the virus.



What if I test positive?

A positive test result indicates that you have been exposed to the Virus and your immune system has produced antibodies in response to the virus.

If you have had no symptoms for at least 7 days, you should have some level of immunity to the Virus and may not be able to transmit the virus to others or become infected by it again.
