The Importance of The Antigen COVID Test In Thornhill

The Antigen Covid Test in Thornhill is a blood test that can help you determine whether or not you have been exposed to the Covid19 virus. The test involves collecting a blood sample from the patient and then placing it into a microscope to view. If there are antibodies present in your blood sample, this indicates that you have had an infection from the virus. Your doctor may order this test if you have recently been diagnosed with a Covid or any other type of respiratory tract infection that causes cold-like symptoms.

The Antigen Covid Test in Thornhill looks for a marker on the surface protein of the SARS-CoV-2 virus to detect active infections. This test is administered through the nose as a sample is gathered by swabbing inside the nose. The results are available almost immediately and can be provided on-site. Laboratories usually conduct this test, but some doctors may also perform it in their offices if they have access to microscopes and equipment needed for testing.

Purpose of the Test

The Antigen Covid Test in Thornhill determines whether an individual is infected with the SARS-CoV-2 virus. It's commonly used for diagnosis. However, it also serves as a means of detecting infection.

•    Diagnosis

With diagnostics and molecular testing like the RT-PCR test, the goal is to quickly confirm an individual's diagnosis that exhibits symptoms consistent with COVID-19. However, since this is a new disease, there are situations in which rapid diagnosis cannot be performed. To counter this problem, antigen testing can be used as a secondary option to confirm a diagnosis.

•    Screening

While Antigen Covid Test in Thornhill looks for the presence of a virus in those exhibiting symptoms, screening involves testing people who haven't exhibited any signs or symptoms. This type of screening is used in more extensive programs where repeated testing might prevent the spread of SARS-CoV-2. While it's relatively cost-effective and quick, it carries the risk of false positives.

When Should You Take an Antigen Covid Test?

The COVID Antigen Test is appropriate when you suspect that you have contracted a COVID Virus and want to know whether or not you have been infected. If you have had close contact with someone who has a COVID Virus, it can be helpful to determine if they have passed the virus on to you.

•    Anyone who had close contact with someone who has confirmed COVID-19 infection, including household members and healthcare workers.
