Epstein-Barr virus is a virus that most of us get infected with at least once in our life... This virus is not very dangerous, but sometimes it becomes a problem for children or people who have a weak immune system... Therefore, by doing tests like Early Antigen Test (EA), the final answer will be determined and then the treatment should be done.. href="https://gcorp.cc/">GCORP LLC, first we will talk a little about the symptoms of this virus, then we will explain the preliminary antigen (EA) test and tell you how reliable this test is....stay tuned.

What is Epstein-Barr virus? (EBV)

Before we talk about this test, we need to talk a little bit about the virus that requires you to take the Early Antigen (EA) test for treatment... Epstein-Barr virus is one of the most common viruses and most people by the age of 40 have been exposed to it at least once. They may feel tired for a few weeks or even a few months.. It will be like that.

Illness symptoms

In many people, the virus has no symptoms. Those who become infected during puberty or adulthood may develop infectious mononucleosis (mono). Common symptoms of this disease include:

• fatigue
• fever
• sore throat
• swollen lymph nodes
• sometimes an enlarged spleen or liver

Of course, it may include other complications such as heart problems and negative effects on the nervous system, which are not very common and occur in rare cases. These symptoms usually disappear after a few months, but EBV remains silent in the person's body until the end of life. Of course, periodic reactivation of the virus may occur, but it usually does not cause symptoms or disease. EBV is usually transmitted through contact with the saliva of an infected person.. to transmit the virus during their lifetime.

This virus spreads quickly through:

• Kissing
• Sharing drinks and food
• Using an infected person's cup, food containers or toothbrush
• Contacting toys with children's saliva on them.

What is the primary antigen (EA) test?

After these symptoms are severe and prolonged, you should see an infectious disease specialist to order a test if needed. An early antigen (EA) test is prescribed to look for a type of antibody that the body normally produces in response to Epstein-Barr virus. These antibodies are usually detectable during the acute phase and reach levels 3-6 months after.>

In many people, detectable primary antibody levels indicate an active infection in which the virus is actively replicating.. This usually occurs during the primary infection, but EA antibodies can also be detected in a latent infection that has been reactivated.... However, in 20% of people, EA antibodies will be detectable for years, even though the virus is not active.

This test is usually done when a person has received inconclusive results from other Epstein-Barr tests... But when symptoms related to the virus are still present, a primary antigen (EA) test should be done...

So the nuclear antigen antibody test results can be done at the same time as the primary antigen test to help make a more accurate diagnosis.. The result of the primary antigen (EA) test is usually available in 2-3 business days. The desired laboratory has and you should see how many days they will determine this answer according to their equipment.

Primary antibodies are usually detectable about 4 weeks after infection and disappear after 3 to 6 months. In some people, these antibodies may remain undetectable for years, even if they are healthy.

Interpretation of the primary antigen (EA) test result

The result of the primary antigen (EA) test can be positive or negative. The presence of this antibody indicates that the Epstein-Barr virus is actively replicating. But generally, this antibody is only detectable when the virus is active, such as in patients with infectious mononucleosis. 2 or 3 cases of this cancer, respectively 94% and 83% show a positive response to the antibody. In addition, only 35% of patients with NPC type 1 have a positive response.

The specificity of the test is that 82-91% of healthy blood donors and patients who do not have heterotrophic bacteria (HPC) will have a negative test result... In between, maybe 9-18% will show errors and become false positives. Although this level is sufficient to detect the virus, this amount of false screening does not indicate a false positive.

Conclusion

In this article we briefly discussed the symptoms of Epstein-Barr virus... So if you or your child has these symptoms and they do not go away after a few weeks, be sure to see a doctor to prevent more serious complications... In most cases, an early antigen (EA) test is prescribed and the treatment is relatively easy.. and make an appointment online.
