Xiao Huang (pseudonym) is a kindergarten teacher who especially likes children.After getting married, I have been actively preparing for pregnancy. In April, the "big aunt", who had always been regularly postponed for two days. Xiaohuang couldn’t wait to test the early pregnancy test strip. The "two bars" on the test paper made her happy and immediately took this.Good news tells the family.
However, after going to the hospital for examination two weeks later, the doctor told her that she had no need to surgery without conceived, and her mood suddenly fell into the trough.What has actually happened?
Fu Xiazheng, chief physician of the Obstetrics and Gynecology Department of the Pearl River Hospital of Southern Medical University, pointed out that this must start with the principle of early pregnancy test paper testing.
Early pregnancy test strip detects the chorionic gonadotropin (HCG) in the urine. As long as the HCG level in the urine rises, the "two bars" will be displayed on the test strip.
For normal pregnancy, the level of HCG in women’s urine will undoubtedly rise, but in addition, there are some abnormal pregnancy situations that cause HCG levels.
With the "two bars" on the early pregnancy test paper, it is impossible to determine whether it is normal pregnancy. The accurate results need to be based on the hospital’s blood drawing and B -ultrasound.
Abnormal conditions will also turn the test strip into "two bars"
So which abnormal situations will cause early pregnancy test strips to be displayed as "two bars"?
There are three common clinical cases:
1. Extreme pregnancy- "Fetus Evil Lost and Woman"
Under normal circumstances, fertilized eggs are formed after sperm and egg fertilization. The fertilized eggs must be swimming to the uterine cavity and bed. In the uterine cavity, "settling home" can develop into embryos and fetuses.If the fertilized eggs are bed in other parts of the uterine cavity, the incidence is about 2%.We can be understood as "fascinated by fertilized eggs, and I have settled."
Chief Physician Fu Xiaye said that the most common part of the abnormal pregnancy is the fallopian tube.After fertilized eggs, HCG will also secrete HCG (human chorionic gonadotropin). It will also display "two bars" with early pregnancy test strips.
Xiaohuang was diagnosed as an ectopic pregnancy of the fallopian tube. As the embryo continued to grow, the tube wall of the fallopian tube was invaded, and the occurrence of rupture and bleeding occurred. It would also cause hemorrhagic shock and endangered life.Therefore, the doctor suggested that she perform surgery as soon as possible.
2. Biochemical pregnancy- "Fertilized eggs cannot settle down"
Extra pregnancy is "settling home", while biochemical pregnancy is that fertilized eggs fail to bed in the uterine cavity.
In the process of "setting up", the HCG level will increase over excessiveness. The "two bars" can be measured through early pregnancy test strips. Blood testing is also positive.However, ultrasonic examinations are not detected in pregnancy signs such as gestational sacs, yolk cycles.
In fact, biochemical pregnancy is not uncommon, this situation accounts for 25%-30%of total pregnancy.In some cases, the biochemical pregnancy is "silent".Because it does not cause special discomfort and cannot even find it.
Q: Why do biochemical pregnancy occur?
A: Chromosomal abnormalities are one of the main causes of biochemical pregnancy.From this point of view, it can be said that the survival of nature is the survival of nature.In addition, the lack of luteal function, abnormal immune, and endometrial factors may also cause biochemical pregnancy.
Therefore, if the early pregnancy test strip is displayed as two bars, but the color gradually becomes lighter, or the level of HCG is gradually reduced, and the ultrasonic examination cannot be seen in the biochemical pregnancy.
3. Portuguese tires -3 Nourishing cells abnormal hyperplasia
"Portuguese" is also a situation of abnormal pregnancy.
The fertilized eggs come to the house in the uterine cavity, but the fluff nourishing cells are abnormally proliferated, forming a variety of blisters. These blisters are connected into a string, and the appearance looks like grapes. Therefore, it is called "hydatidal tires".
In addition, there may be discomfort such as vaginal bleeding and abdominal distension.There will also be typical signs in ultrasound -a normal gestational sac or yolk sac is not seen in the uterine cavity, which is replaced by honeycomb or snow -like tissue.
Q: Why does the fertilized eggs develop abnormally?
A: Most of the "hydatidal" has chromosomal abnormalities.If vitamin A and animal fats are lacking in the diet, the chance of "hydatidica" occurs significantly.
If you are pregnant with a "hydatidal", the situation is more complicated.Only through the Qing Palace surgery, and it must be hospitalized. Under the condition of full preparation, it is completed by an experienced doctor.
In addition to normal pregnancy, early pregnancy test strips may also be "changing multiple -end" ectopic pregnancy, "silent" biochemical pregnancy, "exquisite weird" hydatidum …
The beautiful eyebrows who prepare for the test strip saw the "two bars" of the test strip. Do not blindly stole fun, let alone take it lightly. It is best to go to the hospital to draw blood and B -ultrasound to eliminate abnormal pregnancy.
