Embodiment 1

[0014] Embodiment one, a kind of eugenic test paper, with reference to attached figure 1 , the middle part of the eugenic test paper bottom plate is nitrocellulose membrane 1, and there is an anti-estradiol (E 2 ) Monoclonal antibody detection line 2, one end of the bottom plate is a water-absorbing layer 3, the other end is a glass fiber sample layer 4, and the two ends of the nitrocellulose membrane 1 overlap with the water-absorbing layer 3 and the glass fiber sample layer 4 respectively For connection, a layer of anti-estradiol (E2) monoclonal antibody gold label pad 5 is sandwiched between the glass fiber sample layers, and the reaction value of the detection line 2 is set to be greater than or equal to 50pg / ml. The two ends of the nitrocellulose membrane 1 in the eugenic test paper overlap with the water-absorbing layer 3 and the glass fiber sample layer 4 respectively, and the connection part is in the range of 1-4 mm.

Embodiment 2

[0015] Embodiment two, the eugenic test paper sample layer 4 is put into the tested urine, the anti-estradiol (E) sandwiched in the sample layer 4 2 ) Monoclonal antibody gold label pad 5 reacts specifically with the estradiol (E2) antigen in the urine, and under capillary action, the estradiol (E2) antigen in the urine moves forward along the nitrocellulose membrane 1, Transfer to the estradiol (E 2 ) monoclonal antibody region, estradiol in urine (E 2 ) Antigen in the detected line anti-estradiol (E 2 ) monoclonal antibody recognition, the detection line will display red, and the depth of the detection line color and estradiol in urine (E 2 ) is directly proportional to the level of hormone content. Perform urine self-test every day five days before the next menstrual period. The day when the color of the eugenic test paper changes from light to dark, and then dark to light, is the ovulation day or eugenic intercourse day of the tested woman.

Abstract

The invention discloses prenatal test paper. A nitrocellulose membrane is arranged in the middle of a prenatal test paper bottom plate; an anti-estradiol (E2) monoclonal antibody detection line is arranged on the nitrocellulose membrane; a water absorption layer is arranged at one end of the bottom plate, a glass fiber sample layer is arranged at the other end of the bottom plate, the two ends ofthe nitrocellulose membrane are respectively connected with the water absorption layer and the glass fiber sample layer in an overlapping manner, a layer of anti-estradiol (E2) monoclonal antibody gold-labeled pad is clamped in the middle of the glass fiber sample layer, and the reaction value of a detection line is set to be greater than or equal to 50pg/ml. According to the prenatal test paper,the optimal prenatal opportunity can be finally obtained by confirming the ovulation day.

Description

technical field [0001] The invention relates to a eugenic test paper for helping couples of childbearing age to choose the best time to conceive and to confirm the ovulation day (best time for conception) of women, which belongs to the fields of family planning supplies and OTC products. Background technique [0002] Eugenics is the most important issue in marriage and family. Eugenics is the science of using the principles of genetics to ensure the normal viability of offspring. Originated in England, it means "healthy heredity". Mainly to study how to use effective means to reduce the incidence of fetal defects. Eugenics has become an important medical technology and national policy. Its main content is to use B-ultrasound, chromosome, and genetic diagnosis techniques to screen and control newborns with congenital diseases, so as to gradually improve and improve the genetic quality of the population. Technological means can be used to ensure the health of the fetus. The...
