Description
Technical field
The present invention relates to the biologic applications technical field, particularly the test strips of a kind of Quantitative detection HCG and detection method.
Background technology
After embryonated egg is implanted the uterus, will secrete a kind of new hormone in pregnant woman's body, be called human chorionic gonadotrophin (Human Chorionic Gonadotrophin is called for short HCG).HCG was found in urine of pregnant women by Aschheim and zondek first in nineteen twenty-seven.HCG is a kind of hormone of cytotrophoblast and plamoditrophoblast secretion, and it at first is present in the placenta, is excreted in the urine by blood circulation.In placenta, blood and urine, all there are HCG and metabolic product thereof.After becoming pregnant, about 10 days, just can in pregnant woman's urina sanguinis, detect HCG.In the normal pregnant women serum, HCG concentration after corpus luteum reaches peak value 7～10 days or embryonated egg are implanted and are begun after postuterine 4～7 days to increase, and increase with exponential form, and average per 1.5～2 days concentration is just double, also varies with each individual but advance the speed.Gestation after 7～10 weeks the HCG concentration just can reach 20,000～100,000IU/L, decrease in gestation 13～15 when week concentration, begin again afterwards slowly to increase until 30～33 weeks of gestation, and slowly reduce until the gestation end.Ectopic pregnancy HCG rises then slower, or 3～6 conceived weeks, and HCG can not continue double increase, should consider the possibility of ectopic pregnancy or threatened abortion.
HCG is the main signal in the early pregnancy, and specificity marker has become the common counter of diagnosing clinically early pregnancy.Quantitatively dynamic monitoring HCG amount is also as the monitor control index of ectopic pregnancy.
The method of early detection gestation mainly contains three kinds: Ultrasonic Detection, examination of basal body temperature and immunochromatography detect.Ultrasonic Detection be owing to can only detect gestation situations in uterus after 6 weeks, and is normally used for the clinically monitoring of fetus.But although examination of basal body temperature is simple more loaded down with trivial details.Immunochromatography detect since it easy and simple to handle, have directly perceived, fast, the advantages such as detection efficiency is high, method is easy, pollution-free, expense is cheap, highly sensitive, high specificity, be widely used in clinical diagnosis, field condition and familial self and detect.
The reagent that immunochromatography detects HCG uses double antibody sandwich method.After test fluid was soaked or splashed into the sample pad of test strips, by the capillary action of water-absorption fiber, test fluid is drenched gold-marking binding pad rapidly, and the collaurum bond on the gold-marking binding pad is dissolved, and moves forward along chromatographic material with test fluid.If there is determined antigen Ag in the test fluid, then it will with the collaurum bond in antibody generation specific immune response, form the immune complex of collaurum bond-determined antigen.Then flow through with test fluid and be fixed on the capture agent of T line on the Nc film.The capture agent of T line is caught collaurum bond-determined antigen immune complex, namely with this immune complex generation specific immune response, form the immune complex of collaurum bond-determined antigen-capture agent, thereby make collaurum bond-determined antigen immune complex be trapped in T line place.Test fluid continues reach, when the Nc film of flowing through is fixed with the C line of sheep anti-mouse igg antibody, and sheep anti-mouse antibody generation immune response on the collaurum bond that does not react with determined antigen Ag and the C line, thus so that the collaurum bond that dissociates is trapped in C line place.This moment, T line and C line place all had the collaurum bond to be detained, and namely T line and C line place all can observe color (redness or purple), then represent the positive result of testing result, namely in the test fluid determined antigen are arranged; If only C line place observes color, and T line place does not observe color, then represent the negative result of testing result, namely in the test fluid without determined antigen; HCG content is different in the liquid to be measured, and the T line color depth that produces is not identical yet, and along with the increase of HCG content, the T line color will be darker.Yet, then can cause high-caliber " hook effect (hook effect) " at some sample middle and high concentration HCG, be that HCG concentration is when being far longer than the upper limit of detection of colloidal gold strip, HCG records the result and descends with the increase of concentration on the contrary, the T line color shoals on the contrary, in clinical diagnosis, cause the low-level illusion of HCG, make diagnostic result false problem occur.
