Description
Technical field
The present invention relates to medical immunology in-vitro diagnosis fields, and in particular to a kind of immune globulin M detection reagent box and inspection
Survey method.
Background technique
Turbidimetry is widely used in clinical examination work.It is immunoturbidimetry that application is most common now.
The immuno analytical method of early stage is all largely formation, agglutination and the generation of haemolysis by observing sediment
The presence or absence of specific protein and content in sample to be tested are analyzed with the scattering of measurement light caused by aggregate, it is such as immune to expand
Scattered, immunoelectrophoresis, direct and brief introduction blood clotting, passive hemagglutination, complement fixation test etc., these detection methods are at low cost, result is easy
In judgement, technically convenient for grasping, can be widely used for detecting a plurality of types of clinical samples.But since above method operation is numerous
It is trivial, time-consuming and sensitivity and poor accuracy and tend to be eliminated.
Immunoturbidimetry overcomes disadvantages mentioned above, and quantitatively accurate automation can be developed in conjunction with clinical demand
Instrument.Therefore, for immunology detection, the specificity that there is immunoturbidimetry immunology antigen, antibody to combine, and have
Biotrepy feature can detect in body fluid, the micro test substance especially in blood in automation biochemical instruments,
It is a kind of clinical examination practical technique having very much using future.
Immunoturbidimetry (Turbidimetric inhibition immuno assay) is that antigen-antibody combines dynamic to survey
Determine method.The basic principle is that：When antigen and antibody react and suitable (the general provision antibody of ratio in special dilution system
It is excessive) when, under the action of the poly- agent of rush of the soluble immune complex of formation in dilution system, it is precipitated, is formed micro- from liquid phase
Grain, makes reaction solution turbidity occur.When antibody concentration is fixed, the amount of the immune complex of formation with amount of antigen in sample increasing
Add and increase, the turbidity of reaction solution is consequently increased.Turbidity by measuring reaction solution is compareed with series of standards product, Ji Keji
Calculate the content of antigen in sample.
The various detecting instruments developed according to the basic principle of immunoturbidimetry, developed have been widely used in clinical inspection
The many aspects tested, it is the basic functional principle of Blood coagulation instrument optical method and immunization；It is the load rouge in full-automatic biochemical measurement
The measuring principle of albumen, haptens and other protein；It can also be applied to microorganism detection simultaneously.By accurately to more
Kind substance is quantified, and has biggish clinical meaning to the diagnosis, treatment and prognosis evaluation of many diseases.
Clinically used immunoturbidimetry because its sample dosage is few, can directly on automatic clinical chemistry analyzer batch sample
It analyzes, is easy to operate, but the reagent and method established at present all have some shortcoming and defect, are mainly manifested in：
Antibody, it is easy to appear cotton-shaped or flaky precipitate, causes antibody performance to be deteriorated during preservation, repeatability is bad,
The coefficient of variation (CV) becomes larger, and directly contributes reagent testing result inaccuracy, and increase filtration step, complicated for operation, and filters
Antibody may be removed, detection effect is influenced, is affected to patient, requirement is not able to satisfy.
