Description
Technical field：
It the utility model is related to a kind of early pregnancy test paper, and in particular to a kind of early pregnancy half-quantitative detection test paper.
Background technology：
HCG immunizations are to utilize specific binding reaction between immunology antigen-antibody, and detection human chorionic gonadotropin's gland swashs
Element (human chorionic gonadotropin；HCG content) is to judge whether to be pregnant.HCG is to be produced by placenta the gestational period
A kind of raw glycoprotein, can be excluded external by glomerulus.Human chorionic gonadotrophin can be in the women urine after pregnancy
Detect, before early pregnancy in 10 weeks, human chorionic gonadotrophin raises more than 66% when every 48 is small under normal circumstances,
According to human chorionic gonadotrophin content, pregnancy time can determine whether.
The structure of early pregnancy half-quantitative detection test paper includes test paper and housing, and test paper is arranged in housing, is set in the middle part of test paper
Detection zone is put, on housing, the position of corresponding detection zone, which is set, to be used for easy to the observation detection zone (detection zone (T1/T2/ of test paper
T3 HCG antibody) is coated with, quality control region (C) is coated with anti-mouse IgG, matches somebody with somebody confrontation HCG containing colloid gold label in colloidal gold pad
Antibody) opening, test paper one end protrusion housing outside, when in use, it is necessary to detection urine be contained in cup body, user hold
Housing, one end of test paper is probeed into cup body, one end of test paper is contacted with urine (sample), urine is oozed by one end of test paper
Such as be positive sample thoroughly to detection zone, the determinand in sample is first reacted with the gold labeling antibody in colloidal gold pad, formation antigen-
Gold labeling antibody compound, when chromatography is to detection line on nitrocellulose filter, can form antibody-antigene-gold with coated antibody and mark
Antibody complex, and a red response line is ultimately formed on detection zone (T), result is the positive at this time；Detection zone (T1/T2/
T3) each colour band colour developing is proportionate with human chorionic gonadotrophin content in sample, contains according to human chorionic gonadotrophin
Amount, so that it is determined that pregnancy time.As there is no thing to be checked in sample, then compound cannot be formed, redfree reacts on detection zone (T)
Line occurs, and result is feminine gender at this time.No matter HCG whether there is in sample, and a red response line can all appear in quality control region
(C) in, it is to determine whether there is enough samples, the whether normal standard of chromatography process, while also serves as the inner quality standard of reagent.
In the prior art, when test paper one end is probeed into cup body, test paper is directly contacted with bottom of cup in the presence of damage test paper
Hidden danger, vacantly in cup body, user is difficult to hold hanging depth test paper again, causes inconvenient for use.
