Immunoglobulins Sentence Examples
Within 1 month of glucocorticosteroid therapy, reduction in serum immunoglobulins is noted because of increased catabolism.

The exact cause of the low levels of serum immunoglobulins is usually not known.
Congenital thyrotoxicosis is due to the passage from the mother to the fetus of maternal immunoglobulins that stimulate the fetal thyroid.
This may include transfusions of platelets, intravenous immunoglobulins, or prednisone.
The key component in colostrum and breast milk is immunoglobulins or antibodies that serve to protect the infant against infections or viruses.
The antigen/antibody complex can be detected in the laboratory by adding specific immunoglobulins that are linked with a radioactive dye.
A titer is the serial dilution of antibodies (protein molecules or immunoglobulins produced by the immune system in response to specific disease agents) found in blood serum that determines their level of concentration.
The test is performed by various methods in the clinical laboratory and may also be referred to as viral immunoglobulins testing.
False negative and false positive results can occur with the TORCH test for immunoglobulins because of cross-reacting antibodies, especially among the different types of herpes viruses.Advertisement
In A-T children, B-cell responses are very weak, and levels of immunoglobulins, the proteins that B-cells make to fight infection by specific recognition of invading organisms, may also be low.
These chromosomal abnormalities often occur close to genes that control the function of white blood cells, such as immunoglobulins and T-lymphocytes.
For patients who have normal levels of immunoglobulins and normal antibody responses to vaccines, immunization with influenza and pneumococcal vaccines may be helpful.
The quantitative test measures the levels of the different types of immunoglobulins in the blood as well as the total level of all immunoglobulins.
In these disorders, specific diseasefighting antibodies (immunoglobulins such as IgG, IgA, and IgM) are either missing or are present in reduced levels.Advertisement
These antibodies are specific proteins (immunoglobulins) produced by the immune system to respond to bacteria, viruses, fungi, parasites, or toxins that invade the body.
Immunoglobulin G (IgG) is the most abundant class of immunoglobulins, directed toward viruses, bacterial organisms, and toxins.
Immunoglobulins are made by white blood cells known as B cells (B lymphocytes).
Defects in the thymus gland that manufactures T lymphocytes or defects in the T lymphocytes themselves can also result in reduced production of immunoglobulins.
Determining which immunoglobulins are present and which are absent or present in reduced amounts is critical for diagnosis.Advertisement
When immunodeficiency is suspected, levels of the classes of immunoglobulins are measured in blood serum by using a clinical laboratory procedure called electrophoresis.
Immunoglobulin deficiency diseases cannot be cured, but treatment that replaces or boosts specific immunoglobulins can help support immune function in affected children.
The preferred treatment is to give specific immunoglobulins intravenously (immunoglobulin intravenous therapy or IVIG) or subcutaneously.
Common variable immunodeficiency (CVID) is a disorder of the immune system characterized by low levels of specific immunoglobulins, antibodies produced by the immune system to fight infection or disease.
Antibodies are specific proteins (immunoglobulins) manufactured by the immune system to bind to corresponding molecules (antigens) on the cell surfaces of foreign organisms in an attempt to make them harmless.Advertisement
IgG antibodies, the specific immunoglobulins absent or reduced in CVID, are targeted at bacterial organisms, viruses, and certain toxins.
The type of organism causing repeat infection can be a clue to which immunoglobulins are deficient.
It is caused by very low levels of immunoglobulins that result in an impaired immune system.
B lymphocytes manufacture proteins called antibodies (which are sometimes also called immunoglobulins).
The five different types of immunoglobulins are called IgA, IgG, IgM, IgD, and IgE.
Bruton's agammaglobulinemia is a disorder that is present at birth (congenital) and is characterized by low or completely absent levels of immunoglobulins in the bloodstream.
Immunoglobulins are protein molecules in blood serum that function like antibodies.
Although persons with XLA carry the genes to produce immunoglobulins, a genetic defect on the X chromosome prevents their formation.
This defect is not associated with the immunoglobulins themselves, but rather with the B cells in the bloodstream that ordinarily secrete the immunoglobulins.
They are the sole producers of immunoglobulins in the body.
If Btk is missing or defective, the B cells cannot mature and cannot produce immunoglobulins.
Only mature B cells produce immunoglobulins.
Immunoglobulins, however, are vital for combating bacterial infections.
Infants with XLA usually do not show symptoms of the disorder during the first six months of life, because immunoglobulins from their mothers are circulating in their bloodstreams.
Frequent bacterial infections, a lack of mature B cells, and low-to-nonexistent levels of immunoglobulins point to a diagnosis of XLA.
A sample of the child's blood serum can be analyzed for the presence of immunoglobulins by a technique called immunoelectrophoresis.
Immunoglobulins may produce this immunity.
Blood is analyzed to determine the quantity of immunoglobulins in the blood as well as the ability of the immune system to mount an antibody response against common pathogens.
