The precise symptoms of a primary immunodeficiency depend on the type of defect. Generally, the symptoms and signs that lead to the diagnosis of an immunodeficiency include recurrent or persistent infections or developmental delay as a result of infection. Particular organ problems (e.g. diseases involving the skin, heart, facial development ...
The PID disorders (see List of primary immunodeficiencies) and its subgroup, the primary immune regulatory disorders (PIRDs; i.e., disorders of immunity characterized as excessive proliferations of lymphocytes and the development of immune responses against one's own normal tissues [16]), are immune disorders similar to those in IEI.
This is a list of primary immunodeficiencies (PID), which are immune deficiencies that are not secondary to another condition. The International Union of Immunological Societies recognizes nine classes of primary immunodeficiencies, totaling approximately 430 conditions.
Severe combined immunodeficiency (SCID) DiGeorge syndrome; Hyperimmunoglobulin E syndrome (also known as Job's Syndrome) Common variable immunodeficiency (CVID): B cell levels are normal in circulation but with decreased production of IgG throughout the years, so it is the only primary immune disorder that presents onset in the late teens years.
Humoral immune deficiency (including B cell deficiency or dysfunction), with signs or symptoms depending on the cause, but generally include signs of hypogammaglobulinemia (decrease of one or more types of antibodies) with presentations including repeated mild respiratory infections, and/or agammaglobulinemia (lack of all or most antibody production) which results in frequent severe infections ...

Immunofluorescence or immunoperoxidase assays are commonly used to detect whether a virus is present in a tissue sample. These tests are based on the principle that if the tissue is infected with a virus, an antibody specific to that virus will be able to bind to it.
Common variable immunodeficiency (CVID) is an inborn immune disorder characterized by recurrent infections and low antibody levels, specifically in immunoglobulin (Ig) types IgG, IgM, and IgA. [2] Symptoms generally include high susceptibility to pathogens, chronic lung disease, as well as inflammation and infection of the gastrointestinal ...
