Description

A kind of direct bilirubin detecting kit and collocation method and its utilization
Technical field
The present invention relates to a kind of kit, and in particular to a kind of direct bilirubin detecting kit, and there is provided the reagent The collocation method of box and utilization.
Background technology
The application of bilirubin direct clinically is relatively broad, has higher clinical value to the judgement of disease, to new life Youngster's sample, which is determined, also important clinical meaning.Non-neonate, can be direct because internal bilirubin metabolism produces jaundice extremely Bilirubin direct level in blood is caused to raise.That is, bilirubin direct level rise can both be caused by physiologic jaundice, can also Caused by pathological jaundice.
The common method of bilirubin direct is Vanadic acid oxidation, and existing Vanadic acid oxidation determines icterus neonatorum mark This when, detection data are easily disturbed by jaundice, increase its exception, very big interference is brought to clinical diagnosis, causes clinical assays As a result inaccurate, influence clinician correctly judges patient status.And after clinic is accurately judged as physiologic jaundice, it is surveyed Definite value still can be extremely higher, thus cause clinically can not accurate quantitative analysis bilirubin direct actual concentration.
The content of the invention
The technical problems to be solved by the invention are icterus neonatorum samples have to the measure of existing bilirubin direct it is dry Disturb, it is therefore intended that a kind of direct bilirubin detecting kit of offer, jaundice is to direct bilirubin detecting in solution neonate's sample The problem of interference.
The present invention is achieved through the following technical solutions:
A kind of direct bilirubin detecting kit, including direct bilirubin detecting kit body, and Emulgen A-90 and/ Or Emulgen B-66.
The present invention is effectively reduced or even eliminated by adding Emulgen A-90 and/or Emulgen B-66 in reagent The interference that icterus neonatorum sample is brought, improves the authenticity of direct bilirubin detecting.
Learnt by experiment, while when adding Emulgen A-90 and Emulgen two kinds of materials of B-66, icterus neonatorum The interference that jaundice is brought in sample is minimum, detects the accuracy highest of obtained data;And the Emulgen A-90's is dense Spend for 1~10g/L, when the concentration of the Emulgen B-66 is 1~10g/L, as shown in table 2, can effectively eliminate neonate yellow The interference that subcutaneous ulcer sample is brought, makes Detection results most accurate.
Preferably, the direct bilirubin detecting kit body includes reagent 1 and reagent 2,
The reagent 1 includes:
100~150mmol/L of citric acid
1.5~3.5g/L of NaOH
4.16~5.12g/L of HAS
1.0~1.5ml/L of PC300;
The reagent 2 includes:
20~50mmol/L of citrate dihydrate trisodium
2.2~4.2g/L of citric acid
0.8~1.2g/L of sodium metavanadate
0.5~1.0ml/L of Sodium azide
0.5~3.0mmol/L of disodium ethylene diamine tetraacetate.
A kind of collocation method of above-mentioned direct bilirubin detecting kit, including:
(1)The configuration of reagent in direct bilirubin detecting kit body is completed first,
(2)After Emulgen A-90 and/or Emulgen B-66 are dissolved with water respectively, it is slow added into reagent, when When Emulgen A-90 and Emulgen B-66 are added, first add Emulgen A-90 and be sufficiently stirred for mixing, it is then slow again Emulgen B-66 are added to be sufficiently stirred for mixing;
(3)Constant volume.
Emulgen A-90 and dissolving of the two kinds of materials of Emulgen B-66 in direct bilirubin detecting kit body Degree is relatively low, and being directly added into bilirubin direct reagent to be completely dissolved, and the effect played in reagent can be caused to subtract completely It is weak.The present invention is tried using direct bilirubin detecting is then added to after dissolving Emulgen A-90 and Emulgen B-66 in water In agent box body, the problem of it can not be completely dissolved is prevented effectively from, meanwhile, after being dissolved and added by the method for the present invention The declines that conventional addition manner causes it played in reagent can be prevented effectively from, effect is notable.
Present inventor draws after experiment and research many times, as the Emulgen A-90 and Emulgen When B-66 solution temperature is 35~39 DEG C, the function influence played to it in reagent is minimum, and can have at such a temperature Effect is completely dissolved Emulgen A-90 and Emulgen B-66, plays it and preferably acts on.
Preferably, the solution temperature of the Emulgen A-90 and/or Emulgen B-66 are 37 DEG C.
Preferably, the direct bilirubin detecting kit body includes reagent 1 and reagent 2,
The configuration process of the reagent 1 is as follows:
Sequentially citric acid, sodium hydroxide, HAS, PC300 are added into purified water, after the completion of the dissolving of former material Latter material, water suction piping and druming, then Emulgen A-90 and/or Emulgen B-66 are added repeatedly after PC300 additions are added again Enter rear constant volume;
The configuration process of the reagent 2 is as follows:
Sequentially Sodium Citrate, usp, Dihydrate Powder, citric acid, sodium metavanadate, Sodium azide, disodium ethylene diamine tetraacetate are added into purified water, Latter material, last constant volume are added again after the completion of the dissolving of former material.
A kind of direct bilirubin detecting kit of the present invention, its bilirubin direct for being applied to all blood samples is surveyed It is fixed, but its utilization best results on icterus neonatorum sample, it can be prevented effectively from what jaundice in icterus neonatorum sample was brought Interference, the degree of accuracy highest for detecting it.
The present invention compared with prior art, has the following advantages and advantages:
1st, the present invention can the interference that is brought by Samples detection of effectively anti-icterus neonatorum, by Emulgen A-90 and Emulgen B-66 can significantly solve the false higher phenomenon of measurement result that icterus neonatorum is brought very much, make icterus neonatorum mark This accuracy in detection is greatly improved;
2nd, collocation method of the invention can effectively be such that Emulgen A-90 and Emulgen B-66 is sufficiently dissolved in reagent, send out Emulgen A-90 and Emulgen B-66 are waved preferably to act on.
