Abstract

The invention relates to an IgM (immunoglobulin M) antibody detection test strip, comprising an IgM antibody detection line, wherein a matter capable of absorbing human IgM and rheumatoid factors is coated in front of the IgM antibody detection line. Preferably, the matter is an anti-huamn IgG antibody, Protein G and human IgG aptamer; both the IgM antibody detection line and the matter are both on a nitrocellulose membrane; or the matter is on an absorption pad in front of the IgM antibody detection line, and the absorption pad can be arranged between the nitrocellulose membrane and a combined pad, and also can be arranged between the combined pad and a sample pad. The IgM antibody detection test strip provided by the invention can simply and quickly detect the IgM antibody, obviously improve the detection accuracy, provide a powerful support for the next accurate treatment and is suitable for large-scale promotion and application.

Description

technical field [0001] The invention relates to the technical field of clinical diagnosis, in particular to the technical field of antibody detection test strips, in particular to an IgM antibody detection test strip. Background technique [0002] Immunoglobulin (Ig) is a globulin with antibody activity or chemical structure similar to an antibody; it is an important class of immune effector molecules, most of which are gamma globulins, consisting of two identical light chains and two Composed of the same heavy chain, it exists in two forms in the body: soluble immunoglobulin exists in body fluid, has antibody activity, and participates in humoral immunity; membrane immunoglobulin is a B cell antigen receptor. [0003] Immunoglobulins are produced by lymphocytes of the immune system of higher animals and can be converted into antibodies after being induced by antigens. Due to different structures, it can be divided into five types: IgG, IgA, IgM, IgD and IgE. [0004] The ...
