The immunology tests help in measuring the different levels of the types of antibodies present in your bloodstream. Your immune system is responsible for producing the antibodies in order to protect your body from any bacteria, the viruses, and the different allergens.

The body produces these different antibodies, and the immunoglobulins, to fight foreign material.

Uses of Immunological Tests

The different Immunological tests aid in diagnosing any congenital or the acquired immune diseases, it also helps in differentiating them between the different forms of diseases such as:

Why to get Immunology Test done?

The healthcare professionals that look for the immunoglobulin levels and in case a person that has an infection or somebody who is being protected from getting any significant infection. The healthcare professionals also use the immunoglobulin tests to help diagnose any immunodeficiency (less working of the immune system)

What are symptoms of weak immune system?

The following symptoms determine and indicate a weak immune system

Which Tests Are Done In Immunology?

The Diagnostic Tests that are done for the Immunology Department are as follows:

These tests are done to determine the compatibility in the following:

These tests are also further done in determining the paternity, and in diagnosing any HLA-related disorders, for example: Autoimmune Diseases.

These tests can be done at Ganesh Diagnostic and Imagining Centre, the 24 hour open pathology lab.

Negative Immunology Test Meaning

The negative tests of your antibody would indicate that antibodies of that particular virus were not being detected in the sample.

This could also indicate that if you have not been previously infected with any specific disease. Over the past many years, if you have acquired this disease, but the body has not been able to produce or have not yet formed any detectable antibodies.

Frequently Asked Questions


The Humans are said to be having 3 types of immunity. This is as follows:

  • Innate
  • Adaptive
  • Passive

It is seen that your innate immunity: Every Individual is born with an innate (or your natural) immunity, this is considered to be a type of general protection method.

  • Infectious Disease
  • Agglutination Tests- (ex., latex agglutination, co-aggregation)
  • Agglutination Tests- Very small particles (ex. latex beads, gelatin particles, bacteria) are joined to the reagent antigen or an antibody
  • Enzyme Immunoassays
  • Complement Fixation
  • Precipitation Tests
  • Western Blot Test

In the most Common Immunology along with Serology Tests, the individuals are tested to understand and determine the compatibility for the following: an organ, the tissues, and in case of bone marrow transplantation. Moreover, these determine the paternity, and it is also used to diagnose any HLA-related disorders such as individuals that are having certain autoimmune conditions.

The immunoglobulins in your blood test are used to measure your amounts of IgM, IgG, and IgA in the bloodstream. This further helps in diagnosing the different types of health conditions and issues. In these conditions, it is possible that your immune system is getting affected.

The Serum or Blood is considered to be the preferred sample or sample of choice for conducting the immunology tests. Your Body fluids (ex. peritoneal fluid) and the urine must be submitted in the red top labeled tubes for the procedure of electrophoresis. The CSF sample must be submitted for the EDTA or in the red top tubes for ELP.

In the Enzyme immunoassays, there could be enzyme-linked immunosorbent assays (ELISA), which are the blood tests that would quantify your bacterial antigens or the antibodies that are produced by your body. The ELISA is known to be a colorimetric assay that would change the color if your target antigen or the antibodies are present in a single sample.

For carrying out the immunology tests, the immunologists could use: The Patch tests, which would help identify any specific substances that could cause an allergic skin reaction. For the same, a skin prick test would be done to identify any specific immediate allergies to either the environmental or the food triggers. The Antibody tests are used to measure levels of the antibodies present in the bloodstream.

In the laboratory tests, or the sensitive devices, this would measure amount of the bound antibodies which are based on an extent of the light or the color reaction. Greater is the reaction, more of the substances or the germs or the microorganisms are present. For your Laboratory tests, it would end up taking longer than the rapid tests. They are also considered to be more accurate.

In the rapid tests, your antibodies are usually to be found on the paper strips (test strips, at times the glass will be used too. Your Rapid tests are known to be easy to use and it also provides any instant results. However, they are not considered to be as sensitive as the laboratory tests and it also can't determine exactly how these substances or microorganisms are present.
