What is an antibody test and why do you need it for Covid-19? Antibodies are produced by the body’s immune system in response to foreign substances (called antigens). The antibodies produced are specific to that antigen. When a person has an infection, their body produces antibodies to fight off the disease. These antibodies remain after the infection is cleared and can be detected by a blood test.
- What Is An Antibody Test?
An antibody test measures the presence of antibodies in the bloodstream. Antibodies are proteins that the immune system makes to fight off foreign invaders like bacteria and viruses. Antibody tests can be used to test for autoimmune diseases like a food allergy, or a blood-related disease like anemia. In our case, we can use it to detect COVID-19.
To determine if your antibody levels are sufficient for you to be considered “ immune-competent,” you need to visit your doctor’s office for an in-person blood test. If you’re diagnosed with COVID-19, the antibodies will likely be falsely high and you could develop complications. The Centers for Disease Control and Protection (CDC) recommends that people with an indicated COVID-19 test get their results within 2 weeks of taking an indicated COVID-19 medication.
Receiving a positive antibody test result does not guarantee you will develop COVID-19, just that it indicates that you’re immune to the infection. A negative antibody test result does not necessarily mean you are protected from the infection either, such as when you’re being treated for COVID-19 while taking antibiotics. In fact, even a negative antibody test result does not eliminate the risk of being exposed to the infection — it merely identifies your immune system as being sufficiently resistant to the disease. A vaccine for COVID-19 is currently available for everyone. So, if you haven’t been vaccinated yet, you should be making plans to get it done soon. Testing is the only way to ensure that you are immune and appropriately protected from the infection.
- Why Do you need it for COVID-19?
In today’s world, need is defined differently than the traditional way. People need to know if they are considered ‘high need’ or ‘ low need.’ The low need is defined as having 1 or fewer antibodies that are produced after exposure. The high need is defined as having 4 or more.
Antibodies fall into 1 of 2 categories. There are 2 types of these physical tests.
-You probably already know about the small blood test. This is the easiest way to test for antibodies.
-Another popular option is the passive presence (PP) blood test. This is a very accurate test. People take 2 tablespoons of blood and their PPG level measures how active the immune system is (1-4 units). Active (4- units) is assessed by producing antibody but the antibody also gets into other bodily tissues. This is the intermediate step in the antibody test. This is also called a local antibody. PP tests are done on a single sample. The same technology is also used to measure discrimination (self-titration) and exemption.
It is very important that everyone is properly educated about the current testing strategy and the objective of the tests. To get the most accurate results, it is important to get history as well as a physical check-up.
Remember; you can be positive or negative for COVID-19 antibodies — it’s as simple as that.
- The Importance Of Antibodies & Immunoglobulins In The Human Body:
Antibodies are a type of protein found in blood and other bodily fluids. They are created by plasma B cells in response to antigens, which are foreign particles that the body identifies as potentially dangerous. Antibodies bind to antigens, which allows the body to destroy the antigens and prevent them from causing disease. There are two types of antibody tests available:
A; Pennington Biometric Array;
This test only requires a small blood draw to be completed. It is provided by your physician or regional specialty center, and can usually be administered in about 45 minutes. A positive result means your body is producing antibodies and might be more likely to be protected against the illness.
B; Britain’s COVID-19 Antibody Initiative (BACEI)
This antibody test looks into at least 98 different antigens. The antibody in this test looks for only four different proteins. A negative result means your body is not producing antibodies and how likely it is to fight off the infection is unknown.
The rationale behind using an antibody test for COVID-19 is that the antibody test is faster to perform and more widely available. Once you receive the results from your antibody test, treatment recommendations based on your medical history and your current physical state can be quickly communicated to your care providers and your medications.
An antibody test is a gold standard for identifying sensitivity or specificity in treatments given for COVID-19. When choosing an antibody test, mention to your physician or regional specialty center whether you have had a prior COVID-19 infection in the past 3 months. Also, mention how you have previously responded to treatment and if there are any new or noteworthy symptoms, such as the sudden onset of fever.
- How To Get An Antibody Test?
Getting an antibody test is easy, but it’s important that you go to a doctor you trust. By default, the COVID-19 test looks for antibodies by using an enzyme immunoassay kit. However, it is possible to order a more advanced test kit in this situation. This test requires a specific laboratory and test results within a certain time frame. The most common difference is the sensitivity and specificity of the test. It is common to get one or more COVID-19 tests during the COVID-19-innovation.
