Do you know about the immunoglobulin blood test? Or rather, do you know when you should do the immunoglobulin test?

To receive information about this test and its necessity, follow this article from GCORP LLC.

What is a blood test?

Testing a sample of blood in a laboratory is called a blood test.... Doctors order blood tests to check things like glucose, hemoglobin, or white blood cells.... Blood tests help them diagnose diseases or problems.... Sometimes blood tests help doctors measure the function of an organ (such as the liver or kidneys).

What is the immunoglobulin test (IgA, IgG and IgM)?

In this test, the amount of antibodies in the blood is determined.... As you know, the body's immune system makes antibodies to protect it against bacteria, viruses and allergens.

The body produces various antibodies or immunoglobulins to fight against pathogens....for example, the chicken pox antibody is not the same as the measles antibody....sometimes the body unintentionally makes antibodies against itself and treats healthy tissues and organs like a foreign invader....this condition is called autoimmune disease.

The types of antibodies are:

  • ImmunoglobulinA or (IgA)
    is present in the inner lining of the respiratory tract and digestive tract, as well as saliva, tears and breast milk.
  • ImmunoglobulinGor (IgG)
    is the most common type of antibody found in blood and other body fluids and protects the body against viral and bacterial infections.. It takes some time for IgG to develop after contracting a disease or developing immunity.
  • ImmunoglobulinMor (IgM)
    This type of antibody, which is mostly found in blood and lymph fluid, is the first antibody that the body produces to fight a new infection.
  • Immunoglobulin E or (IgE)
    is naturally present in small amounts in the blood. When the body overreacts to an allergen or fights a parasitic infection, its amount increases.
  • ImmunoglobulinDor (IgD)
    We know little about this antibody and it is present in a small amount in the blood.

If you have not yet had an immunoglobulin test, it is best to consult your doctor using Instant Online Consultation.

What is the reason for performing the immunoglobulin test?

A doctor measures the amount of immunoglobulin to determine whether a person has or is immune to a disease.. This test is also used to diagnose immunodeficiency (when the immune system is not working properly)..

How to prepare for an immunoglobulin test

Children can eat and drink before the test, unless they are having another test at the same time that requires fasting....If your child is taking medication, tell the doctor because some medications can affect the test result.

It is better to wear short-sleeved clothes or t-shirts and you can take a toy or book with you to distract the child.

How is the immunoglobulin test done?

In most blood tests, some blood is drawn from a vein.... Expert to do this:

  • Cleans the skin.
  • He ties an artery band to the arm to swell the vein.
  • Inserts the needle into a vein (usually the back of the hand or the back of the elbow).
  • Pours the blood sample into a glass or small syringe.
  • Opens the ligament and removes the needle from the vein.

Sometimes a blood sample is taken from the fingertip... The specialist will clean your finger and scrape the tip with a fine needle (or lancet) to take a blood sample.

A blood sample is taken from the heel of the babies.. for this purpose, after cleaning the heel, the specialist inserts a small needle in this area to collect the blood sample...

Most blood tests only take a few minutes.... Sometimes the vein is hard to find, so the nurse tries more than once.

The nurse will remove the tourniquet and needle and apply cotton or a bandage to the affected area to stop the bleeding.. The area may bruise slightly, which will heal within a day or two.

If you are unable to go to medical centers due to physical or occupational conditions, you can easily get the test you need by using on-site testing.

When will the antibody test result be ready?

It may take a few days for the result to be ready... If the results indicate a problem, the doctor will order more tests to diagnose the problem and how to treat it.

Is the immunoglobulin test dangerous?

This test is safe and there is the least possible risk to perform it.... Some children faint or feel dizzy after the test.... Some children and teenagers are also very afraid of needles.... If your child is anxious, consult the doctor before the test to find out what methods will help ease the situation.

A small bruise or sore around the area where the blood was drawn is normal and may last a day or two....If the pain worsens or persists, it is best to see a doctor.

What do antibody test results mean?

After receiving the result of your antibody test, it is better to go to a specialist doctor to analyze the results for you in detail... In the following, we have collected some of the most important antibody test results for you.

1) If the IgG test result is positive, what does it mean?

If the test is positive (antibodies are present in your body), you have probably already been infected with the virus that causes Covid-19.. Of course, the antibody may indicate that you have already been infected with other types of coronavirus.

Other corona viruses cause colds... Also note that the test result may be wrong.

The presence of IgG indicates that the disease occurred within the last few weeks to several months....Also, it means that you no longer suffer from the disease....The presence of antibodies can indicate whether or not you have developed immunity to the virus.

We don't yet know to what extent the presence of IgG in the body confers immunity.... Your doctor will help you decide the best way to care for yourself based on your test results and other factors related to your medical history, including previous symptoms, exposure to Covid-19, and places you have recently traveled.

2) If the IgG test result is negative, what does it mean?

The negative result of the test means that the antibody to the virus that causes the emergence of Covid-19 is not present in your blood sample.... Some diseases cause the body to have problems in producing antibodies.

But sometimes the test results are wrong in some people... If you test in the first days of the disease and the body has not yet had enough time to produce antibodies, the test result will be negative.... This means that even if the test is negative, you may still have Covid-19.

In this case, your doctor will review the test result along with all aspects of your medical history (such as symptoms, exposure to illness, and geographic location of recent travel) to determine the best course of action for you.

3) What does it mean if your IgM test is positive?

The presence of IgM means that you have been sick for the past few weeks.... It also indicates that there is still a possibility of spreading the disease from you to others... Nasal mucus sampling will definitely determine if you are still infected or not.

Your doctor will help you determine the best way to care for yourself based on your test results and other factors related to your medical history, including past symptoms, exposure to COVID-19, and places you have recently traveled.

4) If the IgM test result is negative, what does it mean?

A negative test result means that the antibody to the virus that causes Covid-19 is not present in your blood sample. However, sometimes the test result is wrong in some people.

If you test in the first days of the disease and the body has not yet had enough time to produce antibodies, the test result will be negative... that is, even if the test is negative, you may still have Covid-19.

In this case, your doctor will review the test result along with all aspects of your medical history (such as symptoms, exposure to disease, and geographic location of places you have recently traveled) to determine the best course of action for you.
