How much does the positive reaction of pregnancy test drug know that it is pregnancy? What do these values mean?
What is the value of 1.hCG?
HCG is an endocrine hormone in human body, and its Chinese name is human chorionic gonadotropin.
HCG is a kind of protein. If a woman is pregnant, it will become a part of the placenta.
In addition, don't think that this is a hormone unique to women, in fact, men also have it!
After the fertilized egg is implanted and pregnancy is confirmed, hCG secretion will increase. HCG can promote luteinization after ovulation and promote the secretion of female hormones such as progesterone and estrogen.
After entering the gestational age, the concentration of hCG in urine and blood will increase. You can use this to check if you are pregnant.
Second, clinically, how much hCG value can be determined as pregnancy?
First, understand the relationship between fertilized eggs and hCG.
After the fertilized egg is implanted, hCG begins to be produced, and the hormone concentration in urine will increase. It may increase from 25IU/ml to 1000 IU/ml after 4 weeks of pregnancy.
The hCG level in urine will increase to 200000 mIU/mL at 8- 10 weeks of pregnancy, reaching a peak.
After this period, hormones will transfer to the placenta, and the content of hCG will gradually decrease.
During pregnancy 15-40 weeks, a certain concentration of hCG will be maintained in the blood. When the placenta leaves the body during delivery, the concentration of hCG will be greatly reduced to zero.
Generally, the test drugs sold by merchants in the market will set the hCG in urine at 50mIU/mL. Once it exceeds this degree, it will produce a positive reaction.
Of course, this test standard also has a certain personal gap. When judging pregnancy, you need to go to the hospital for a more definite examination.
Next, we will continue to tell you the relationship between hCG and pregnancy.
First, how much is the hCG value more than normal pregnancy?
If the pregnancy test results are positive, many people will think that I am pregnant.
Actually, this cognition is wrong.
Pregnancy test drugs need to detect hCG value to a certain level to check whether they are pregnant. Not only positive, but pregnant.
For example, ectopic pregnancy with implantation outside the endometrium, even if hCG is not doubled, the results of pregnancy test are positive.
Under normal circumstances, if a woman is pregnant normally, the amount of hCG in her blood will exceed 1500-2000IU/mL. If the fetal sac is seen at the same time, it can be determined that the fetus is pregnant in the uterus.
If it is an ectopic pregnancy, it needs early detection and early treatment. If a woman finds a positive result in a pregnancy test, she needs to go to the obstetrics and gynecology department as soon as possible.
Second, hCG is only a criterion for judging pregnancy.
HCG is a hormone produced and secreted after pregnancy, and whether you are really pregnant can be judged by pregnancy test drugs.
However, this also varies from person to person. Because there will be positive results near the physiological period, and the degree of hCG increase in urine will vary from person to person, it is necessary for women to check again after the drug test of 1 week.
In addition, the treatment of infertility will also inject hCG, which will increase the hCG value in the body.
In this case, even if you are not pregnant, there will be a positive result. Therefore, women need to pay attention to the use of related drugs.
Mothers-to-be and mothers-to-be are familiar with the hormone HCG, knowing that once the fertilized egg is implanted, a large amount of HCG will appear in the body, so when the test paper for early pregnancy is positive, they will be very happy and will go to the hospital for blood test to see what the HCG value is.
As long as the HCG value exceeds a certain value, it means that you are pregnant, no problem. However, many customers like to compare their values with others. When they see that others have thousands of values and they only have hundreds of values, they are not practical. They are worried that the HCG value is low and the embryo development may be abnormal. Here, Xin 'an International gives you a set of HCG data for your reference:
It can be concluded from the data that the control value of HCG is a range, and as long as it is within this range, it is qualified.
For example, in the fifth week, others measured 2600 international units, and you only measured 75 international units. Don't worry too much. Because fertilized eggs are implanted in sequence, it is normal that she implants early and you implant late, and your value is lower than her. In addition, the HCG value will change with the sex of the embryo.
