Abstract
The present invention relates to test paper used for detecting female infertility and a method for detecting infertility by the test paper, particularly to test paper for detecting infertility and a detection method thereof. The present invention has the technical scheme that the end of a sample pad end of the test paper for detecting infertility is immersed in urine, anti-LH mono-antibody gold mark antibodies clamped in the sample pad and LH antigens in urine cause a specific reaction, and the LH antigens move forward in the direction of a nitrocellulose film under the action of capillaries; when the LH antigens move to the area originally coated with the other anti-LH monoclonal antibody in the nitrocellulose film, sandwich-type specific combination occurs; the LH antigens are recognized by the anti-LH monoclonal antibody in a detection line, and the detection line displays red; the darkness and the lightness of the colors of the detection line are in direct proportion to the content height of LH hormones in urine.
Description
Technical field: the present invention relates to a kind ofly be used to detect the test paper of female infertility and use the infertile method of this detection paper, promptly a kind of infertility detects test paper and detection method thereof.
Background technology: the women has only ovulation, just might become pregnant.Once ovulation only took place in every month in normal women of child-bearing age.Modern science confirms that the secretion of lutropin (LH) hormone can promote the discharging of human body mature egg and corpus luteum to form in the human body, has only normally and when reaching certain amount when lutropin (LH) hormone secretion in the human body, and human body just can start ovulation.Before the ovulation, human body blood can obviously raise with lutropin (LH) value in the urine, when reach a certain amount of after, ovum just can discharge.Medically define: matrimonial cohabitation, sexual life normally, do not adopt any contraceptives, that does not become pregnant in two years after marriage is called infertility.The person that never do not become pregnant after marriage is called primary infertility; Once conceived and contraception have 2 years and the person of not becoming pregnant is called secondary infertility.Tool statistics shows: because the women is former thereby take place infertile to account for 40%, male sex's reason takes place infertile to account for 30%, both sides' reason account for 30%.Because the influence of various factors faces fertility difficulty and sterile Mr. and Mrs' number and constantly rises, it is reported that now just there are 2,500 ten thousand pairs of infertile couples in China in recent years.The medical worker must accurately check at first that as carrying out infertility diagnosis, sterility treatment and observation of curative effect and carrying out the artificial impregnation assurance on opportunity the patient has rule and date, corpus luteum and the ovarian hormone secretion situation of anovulation, ovulation.In other words, accurately detect the amount of women's lutropin (LH) hormone secretion, just can judge that the women has the correct time of anovulation and ovulation, this is the work that the medical worker at first will carry out when the diagnosis of carrying out infertility and treatment.But all using lutropin (LH) radioimmunological kit and lutropin (LH) enzyme to exempt from kit at present both at home and abroad measures, these medicine boxs are mainly used in hospital, need to detect the content of lutropin in the urine (LH) hormone by professional, specialized equipment, need long time and complicated process, can not be used for family and test oneself.
Summary of the invention: the objective of the invention is to overcome the shortcoming of above-mentioned prior art, invent a kind of whether the ovulation with regard to the detection women that can oneself finish and the infertility test paper of lutropin (LH) hormone secretion situation and the method for using this infertility detection test paper to detect at home.
The purpose of the present invention's invention is: the infertility detection test paper of invention design is overlapped mutually by base plate, nitrocellulose filter, water accepting layer and glass fiber sample layer and connects and composes, scribble the detection line of another anti-lutropin (LH) monoclonal antibody at the nitrocellulose filter middle part,, and the reacting value of detection line is greater than or equal to 5mIU/ml; By shade and the standard color comparison card contrast that detection line after this infertile detection detection paper urine shows, confirm whether lutropin (LH) hormone is normal in the tested human female.
The objective of the invention is to finish by following method and structure: a kind of infertility detects test paper and detection method thereof, it is characterized in that the base plate middle part is nitrocellulose filter, an anti-lutropin (LH) monoclonal antibody detection line is arranged on the nitrocellulose filter, end termination at base plate is an adsorptive pads, other end termination is a sample pad, accompany the anti-lutropin of one deck (LH) monoclonal antibody gold labeling antibody in the middle of sample pad, the reacting value of detection line is set at and is greater than or equal to 5mIU/ml; The nitrocellulose filter two ends overlap mutually with sample pad with adsorptive pads respectively and are connected, and the part that overlaps mutually is in 2-5 millimeter scope; Test paper sample pad end is immersed in the urine, be clipped in anti-lutropin (LH) monoclonal antibody gold labeling antibody in the sample pad and lutropin (LH) the antigen generation idiosyncrasy in the urine, under capillarity, lutropin (LH) antigen moves forward along the direction of nitrocellulose filter, moved to when originally scribbling another anti-lutropin (LH) monoclonal antibody regional in the nitrocellulose filter, the specific bond of sandwich style takes place, anti-lutropin (LH) monoclonal antibody identification in the just tested survey line of lutropin (LH) antigen, detection line just shows redness, and the depth of its detection line color just is directly proportional with lutropin (LH) hormone-content in the urine.
Test shows: the lutropin in the female body (LH) hormone secretion amount is during less than 5mIU/ml, and the women can not produce ovulation, so infertility of the present invention detects the detection line (4) in the test paper, and its reacting value is set at and is greater than or equal to 5mIU/ml.
The present invention is owing to adopt immunochromatography single stage method principle, and detection line (4) reacting value that infertility is detected test paper is set at and is greater than or equal to 5mIU/ml.Women oneself just can use the infertile detection test paper of the present invention at home, and lutropin (LH) hormone secretion situation in the detection bodies provides the means of a kind of convenience, practicality and fast detecting for detecting infertility, thereby reaches the purpose of auxiliary diagnosis infertility.
