Common variable immunodeficiency is an immunodeficiency disorder characterized by a low level of antibodies. Patients with this disease are subject to recurring infections.
The term 'independent variable' is normally used to refer to the variable that you are investigating in an experiment. A common colloquial definition is 'The variable you change' which is helpful, but not always clear. AQA (A UK examination board) defines it in the following way 'The independent variable is the variable for which the values are changed or selected by the investigator' Aims of experiments are often written in the form 'How does X affect Y?' X would be the independent variable and Y the dependent variable.
The dependent variable.
The dependent variable is the variable that depends on the independent variable.
the test variable is the independent variable.
The independent variable is the variable you change. The dependent is the variable you measure and the contol variable is the variable that you keep the same.
With good medical care, people with common variable immunodeficiency usually have a normal life span.
Treatment for common variable immunodeficiency aims at boosting the body's immune response and preventing or controlling infections. Immune serum, obtained from donated blood, is given as a source of antibodies
The main diagnostic test that distinguishes common variable immunodeficiency from other immunodeficiency diseases is the low antibody level despite the normal number of B cells. Antibody levels are tested in the serum

Examples of Immunodeficiency disorders (IMDC) include common variable immunodeficiency (CVID), Severe Combined Immunodeficiency (SCID), and Wiskott-Aldrich syndrome. These disorders affect the body's ability to fight off infections due to a compromised or absent immune system. Treatment often involves strategies to prevent infections and boost the immune system.
Patients with this disease have frequent infections, especially those caused by the same microorganism. Recurring infections are an indication that the immune system is not responding normally and developing immunity to reinfection.
The disease itself cannot be prevented, but patients and their families can take precautions to prevent the recurrent infections commonly associated with it. For example, good hygiene and nutrition are important, as is avoiding crowds
B cells with IgG antibodies on their surface are capable of responding to microorganisms. The lack of IgG on the surface of the B cells means that they are not prepared to fight infection.
The main symptom is recurring infections that tend to be chronic rather than acute. Patients may also develop diarrhea and, as a consequence of the diarrhea, do not absorb food efficiently. This can lead to malnourishment
