The immune system is one of the most important systems in the human body. It is the impenetrable fortress and the army that protects it against any anti-materials or foreign organisms that may penetrate your body.. Enhancing its health and seeking to strengthen it is your task.. It is also necessary to check on its functions, how it works, and whether the immune cells work regularly. or no? .. Let’s learn in this article about ANA immunity analysis, why it is done, and what is the percentage of natural immunity in the human body.

Antibody immunoassay

ANA immunoassay aims to detect nuclear antibodies in your blood. Normally, your immune system makes antibodies to help you fight and resist any infection, but this function may malfunction and these antibodies start attacking healthy body tissues. By targeting the nucleus of each of these cells, an ANA immunoassay is performed. Usually, the doctor asks for this test from people suspected of having rheumatoid arthritis or scleroderma.

A positive ANA test indicates that your body’s immune system has mistakenly launched an attack on your tissues, but there are people who test positive even when they are healthy and do not have any health problems.

What are antibodies?

They are proteins that your immune system makes to fight bacteria, viruses, and germs. If your body makes a mistake in distinguishing between foreign bodies that invade your body and your cells, this is called autoantibodies that attack cells and tissues in the body. Antibodies can damage joints, skin, muscles, and other parts of the body. As for antinuclear antibodies (ANAs), they are a type of antibody that attack proteins inside the cells of your body.

Why is an ANA immunoassay performed?

Some rheumatic diseases have similar signs and symptoms, such as:

• Arthritis
• Tired
• fever

Although ANA cannot confirm a specific diagnosis, it can rule out some suspected diseases. And if the results of the analysis are positive at that time, you can do a blood test to search for the presence of certain antibodies.

How do you prepare for an ANA immunoassay?

This analysis requires a sample of your blood, and if you are going to do this analysis only, you can eat and drink normally before the test, there is no problem with that, but if you are going to use the same sample to do other additional tests, you may need to fast for a period before taking the sample, and this will be explained to you by your private doctor, There are also some medications that may affect the results of the analysis, so you should tell your doctor if you are taking any medications.

What are the expectations for an ANA immunoassay?

What to expect For an ANA immunoassay, a member of the health care team or the analyzing doctor takes a sample of blood through a needle in a vein in the arm, and then sends it for analysis. You can return to your daily activities immediately after the blood sample is taken.

ANA immunoassay results

The positive results of the ANA immunoassay depend on the presence of antinuclear antibodies, but getting positive results does not mean that you have a disease, as many people, as we explained before, have positive results without any autoimmune diseases, especially women over 65 years old.

Some infectious diseases and some types of cancer have been associated with the development of antinuclear antibodies, such as some drugs, so if your doctor suspects that you have a certain autoimmune disease, he will ask you for a number of other tests and analyzes, and the ANA immunoassay can be considered like the one piece of information that the doctor infers from the information and which direction it will take you based on your signs and symptoms.

The percentage of natural immunity in the human body

The natural immunity ratios in the human body are measured by the rate of white blood cells in the blood. This is because white blood cells are the main component of the immune system and they defend the body against any diseases or infections.

Normally, every person is born with a huge number of white blood cells, but these percentages vary with time and decrease. These percentages are as follows:

• Newborns: Their WBC levels range from 9,000 to 30,000 “per milliliter of blood.”
• Children under two years old: their ratio ranges from 6,200 to 17,000 “per milliliter of blood.”
• Children over the age of two years and adults: their levels range from 5,000 to 10,000 “per milliliter of blood.”

In the end, dear reader, after you have seen the full information about the immune deficiency analysis, you can now know whether you need to conduct it or not..and may you be well.
