Detection of human chorionic gonadotropin (hCG) in urine by early pregnancy test paper. As long as the level of hCG in urine rises, the test paper will show "two bars". Normal pregnancy will undoubtedly increase the hCG level in women's urine, but in addition, there are some abnormal pregnancies that lead to the increase of hCG level. Abnormal circumstances will also turn the test paper into a "two bars".
There are two common clinical situations:
1. Ectopic pregnancy-"The fertilized egg got lost and went to the wrong house"
Under normal circumstances, sperm and eggs are fertilized to form fertilized eggs. The fertilized egg must be able to swim to the uterine cavity and get into bed before it can develop into an embryo and fetus. If the fertilized egg is implanted in other parts of the uterus, it is an "ectopic pregnancy" with an incidence of about 2%. We can vividly understand it as "the fertilized egg lost and settled in the wrong home".
The most common site of ectopic pregnancy is fallopian tube. After the fertilized egg is placed in the wrong house, it will also secrete hCG (human chorionic gonadotropin), and the detection with early pregnancy test paper will also show "two bars". Xiao Huang was diagnosed as tubal ectopic pregnancy. As the embryo continues to grow, it will invade the tubal wall, causing rupture and bleeding, and even leading to hemorrhagic shock, which is life-threatening. Therefore, the doctor advised her to have an operation as soon as possible.
2. Biochemical pregnancy-"fertilized eggs can't settle down"
Ectopic pregnancy is that the fertilized egg is "in the wrong house", while biochemical pregnancy is that the fertilized egg fails to implant in the uterine cavity, "can't settle down" and goes away. In the process of "settling down", the hCG level will rise temporarily, and the "two bars" can be detected by early pregnancy test paper, and the blood test is also positive. However, ultrasound examination can not detect pregnancy signs such as gestational sac and yolk sac. In fact, biochemical pregnancy is not uncommon, accounting for 25%-30% of the total pregnancy. Only in some cases, biochemical pregnancy is "silent". Because it will not cause special discomfort or even be discovered.
Tips: Besides normal pregnancy, the "two bars" of early pregnancy test paper may also be "changeable" ectopic pregnancy, "silent" biochemical pregnancy and "bizarre" mole. Pregnant girls should see the "two bars" of the test paper clearly, don't steal happiness blindly, and don't take it lightly. It is best to go to the hospital to draw blood for B-ultrasound examination to rule out abnormal pregnancy.
