What is a serology test?
It is as a blood test (but can use other fluids) that reveals the number of antibodies that are present in the body when it is responding to an infection or microorganism. In this case, an antibody against Covid-19. An antibody is a protein. Therefore, a test that measures the amount of proteins against Covid-19.
Antigen is the invader into your immune system, examples are bacteria, fungi, virus. Your immune system fights back using antibodies against the enemy.
A serology test does not detect the virus itself! Instead, it detects the antibody against Covid-19, to identify the immune response of the body to the virus.
This test can be helpful for patients that are asymptomatic or with minor symptoms since antibodies will indicate the person had an immune response to Covid-19. U.S Food and Drug Administration (FDA) suggested as possible test to control when somebody can safely return to work.
If immunity is developed, at least, as we know now, more likely you won’t get it again. You already have protection against the virus. Scientist are using blood from recovered patients to study the antibody against Covid-19. And some researchers and hospitals are using these antibodies to save lives by plasma transfusion.
One small downside, since this test measure antibodies, it will probably not be accurate at early stages of the infection, since the immune system has not built a detectable number of proteins against Covid-19. Unless the specificity of the test is extremely high.
COVID-19 and Dentistry
For all health care providers, including Dentistry, this serum test can be beneficial in order to identify patients that already overcame and developed immunity to Sars-CoV-2.
One day, we expect to have saliva tests to identify antibodies for Covid-19. These may even be included as part of a dental exam and checkup.
Every day we are reviewing and adapting new protocols to keep up with the latest information and advances on this fight against Covid-19.
As only dental emergencies can be seen these days, we wanted to emphasize if you are having one please contact Dr. Hervas at Implantation Dental Center. He will assist you in identifying the cause of your dental problem and recommend a treatment to alleviate your discomfort.
