what does immunoglobulins mean?

Question

my daughter had blood tests and these where some that they done

Answer 1

I see someone else has posted a more detail answer, anyway just to make things simpler for you, this is my explanation:

First you'll have to know what's plasma, we can basically define plasma as the fluid in our blood vessels, minus those blood cells.

And now you'll have to know that in the plasma, we'll have some proteins inside it, that's called plasma proteins.

And now to the classification of plasma proteins, one of the plasma proteins is globulin.

Immunoglobulin (Ig) is one of the globulins, also known as gamma-globulins. However, immunoglobulins have 5 types too, namely IgG, IgA, IgM, IgE and IgD, with each type having its own functions, characteristics and also normal values in your blood.

In short, any deviations of Ig level in your blood shows something wrong. But Ig level will change under pathological reasons as well as allegic, injuries, etc.

Answer 2

Immunoglobulins are special concentrated antibody preparations which provide immediate short-term protection against disease for individuals who are at high risk of experiencing severe disease or of developing serious complications from the disease. They can be given via a drip.

Everybody has immunoglobulin in their systems but some have more than others. The blood tests are there to test whether your daughter is able to fight off bacterial and viral infections sufficiently.

Answer 3

To be precise, immunoglobulins are antibodies (proteins secreted by B lymphocytes in a specific immune response) that have not yet been secreted.

IN other words, once secreted into the bloodstream, immunoglobulins becomes antibodies ( jsut a difference in naming)

A high serum antibody level does not really mean anything since it may indicate a past or present infection

Answer 4

An antibody or immunoglobulin is a large Y-shaped protein used by the immune system to identify and neutralize foreign objects like bacteria and viruses. Each antibody recognizes a specific antigen unique to its target.[1] This is because the two tips of the "Y" of the antibody contain a paratope (a structure analogous to a lock) that is specific for one particular epitope (analogous to a key) on an antigen, allowing these two structures to precisely bind together. This precise binding mechanism allows an antibody to tag a microbe or an infected cell for attack by other parts of the immune system, or to directly neutralize its target (i.e. by blocking a part of a microbe that is essential for its invasion and survival). The production of antibodies is the main function of the humoral immune system.[2]

Antibodies are soluble glycoproteins of the immunoglobulin superfamily.[3] The terms antibody and immunoglobulin are often used interchangeably. When attached to the surface of the B cell, the membrane-bound form of the immunoglobulin is sometimes referred to as the B cell receptor (BCR). Soluble antibodies are found in the blood and tissue fluids, as well as many secretions. In structure, they are globulins (in the γ-region of protein electrophoresis). They are synthesized and secreted by plasma cells that are derived from the B cells of the immune system.[4] Membrane-bound immunoglobulins are only found on the surface of B lymphocytes and facilitate the activation of these cells following binding of their specific antigen, and their subsequently differentiation into plasma cells for antibody generation, or memory cells that will remember the foreign antigen during future exposure. In most cases, interaction of the B cell with a T helper cell is necessary to produce full activation of the B cell and, therefore, antibody generation following antigen binding.[4]

Answer 5

These are a class of proteins in the body that deal with the various phenomena of immunity to diseases , induced sensitivity and allergy .

Answer 6

blood count to see how many red cells and white cells you have, test for aenemia and things like that, it will check to how well suited your blood is to resist infections etc? i think

Answer 8

They are the antibodies which fight infection in our body
