The diagnosis of<unk>  can be ascertained in those individuals with this condition via the following: * Delayed hypersensitivity skin test * T<unk>  count * Detection via culture(infection) Types Primary or secondary Lymphoma * Primary (or hereditary) immunodeficiencies of T<unk> s include some that cause complete insufficiency of T<unk> s, such as severe combined immunodeficiency (SCID), Omenn syndrome, and Cartilage–hair hypoplasia. * Secondary causes are more common than primary ones. Secondary (or acquired) causes are mainly: :*AIDS :*Cancer chemotherapy :*Lymphoma :*Glucocorticoid therapy Complete or partial deficiency * Complete insufficiency of T<unk>  function can result from hereditary conditions (also called primary conditions) such as severe combined immunodeficiency (SCID), Omenn syndrome, and cartilage–hair hypoplasia. * Partial insufficiencies of T<unk>  function include acquired immune deficiency syndrome (AIDS), and hereditary conditions such as DiGeorge syndrome (DGS), chromosomal breakage syndromes (CBSs), and B-cell and T-cell combined disorders such as ataxia-telangiectasia (AT) and Wiskott–Aldrich syndrome (WAS).
