Description
Technical field
The present invention relates to Hemostasis examination, be specifically related to a kind of method based on blood sample vibration detection coagulation, belong to blood
Liquid detection technique field.
Background technology
Human body has complicated and complete hemostasis, blood coagulation and anticoagulant mechanism, and the formation of thrombosis is relevant with whole clotting mechanism,
And the research of thrombosis relates to generation and the development of the multiple diseases such as atherosclerosis, coronary heart disease, myocardial infarction；Coagulation analysis
The project checked be widely used in hemorrhage, thrombotic disease and the diagnosis of Pre-thrombosis State, observation of curative effect, anticoagulant dosage and
Prognostic analysis, the various primary or diagnosis of Secondary cases fibrinolytic and observation of curative effect.Automatically coagulation analysis refers to be divided by automatic blood coagulation
Analyzer or other analysers are analyzed to hemostasis and Related Component in thrombosis system and are applied to hemorrhage, thrombotic disease and examine
Break, treat and Index for diagnosis；The application of Automatic coagulometer so that hemostasis and thrombosis item inspection become easy, accurate, can do
Go out multinomial quantitative result accurately.
Full automatic blood-coagulation detects at present mainly following several method: 1, optical method；2, paramagnetic particle method；3, immunoturbidimetry；
The Cleaning Principle of optical method is to determine setting time by the change of detection blood sample turbidity to be measured.Treat test sample
This is during solidification, and the component content of blood all there occurs change, according to lambert's beer's law, when a branch of parallel list
When coloured light is perpendicular through the extinction material of uniform non-scatter, its absorbance just becomes with concentration and the absorber thickness of extinction material
Ratio.When blood constituent changes, the intensity of transmission light and scattered light also can change, and can be used to according to this characteristic optical method
Carry out Hemostasis examination.The shortcoming of optical method is susceptible to interference, the bubble in the fineness of test cup, blood sample, sample to be tested
Turbidity higher (such as situations such as jaundice, hyperlipidemia) all can become the interference factor of measurement.
Paramagnetic particle method refers to add magnetic bead in the sample during detection, utilizes the motion of instrument monitoring magnetic bead thus reacts blood coagulation shape
The detection method of condition.In Blood Coagulation Process, the change of blood viscosity can produce impact to magnetic bead motion, can pass through instrument
Detect this change, thus measure the coagulation of blood sample.The shortcoming of paramagnetic particle method is that Cleaning Principle is complicated, to detection knot
Fruit produces the factor of impact and includes: the degree of sample, and magnetic bead drives coagulated mass motion, and wall of cup and the technique etc. of magnetic bead.
Immunoturbidimetry refers to, when the monochromatic light that coagulo meter light source part produces passes through blood plasma to be checked, add people's examination in specimen
After agent, antigen and antibody response will form composite particles so that the turbidity of specimen to be checked increases, then the light intensity meeting passed through
Weaken.The degree that light intensity changes becomes certain quantitative relation with the amount of antigen, utilize antigen body specific binding instead
Should come detected blood sample to carry out qualitative and quantitative determination, to determine every Solidification Parameters.The shortcoming of immunoturbidimetry is mesh
The blood clotting project that front immunization can detect is less, makes the function of instrument be restricted.Reagent price is high simultaneously, improves measurement
Cost.
