What tests should I do to check if I am pregnant?

When a woman experiences delayed menstruation, she may wonder if she is pregnant. At this time, you can use certain methods to check. For example, the simplest and most commonly used method is the early pregnancy test, which is a method that can be tested at home. If the test is positive during the examination, it generally proves that pregnancy occurs. Of course, it is best to go to the hospital for examination at this time.

What tests should I do to check if I am pregnant?

It is to test the HCG value, that is, the value of human chorionic gonadotropin, which is produced by the placenta. Generally, this hormone will be excreted into the urine through the pregnant woman's blood circulation a few days after the woman is pregnant. Therefore, the morning urine extraction test has the most accurate result, and this method is relatively convenient. If the pregnancy has not been detected in the first few days, it may be because the secretion of this hormone is low. You need to wait a few more days, around the 10th day of pregnancy, then it will be easy to detect.

When testing with a pregnancy test stick, the pregnancy result can be read after 1 minute, that is, two lines are clearly displayed, which is the result of pregnancy. In addition, due to the low HCG hormone content in the urine in the early pregnancy, it may take up to 3 minutes to show the second line to determine whether you are pregnant. The result of not being pregnant must be determined after 3 minutes. If there is still only one control line after 3 minutes, it means you are not pregnant. Results read after 5 minutes will be considered invalid.

What department should I go to if I suspect I'm pregnant?

Four-dimensional color ultrasound is a type of ultrasound examination. In addition to the functions of general color ultrasound, it can also perform three-dimensional imaging of the fetal head and face, and can clearly show the conditions of the eyes, nose, mouth, jaw, etc. It can assist doctors in directly diagnosing congenital malformations of the fetus, including surface malformations, visceral malformations, and head and facial malformations, and can determine the exact position of the fetus in the uterus. In addition, four-dimensional color ultrasound adds time dimension parameters based on these functions, which can observe dynamic activity images of the fetus in real time.

Generally speaking, four-dimensional color ultrasound can reveal major malformations of the fetus, such as congenital heart disease, cleft lip and palate, hydrops fetus, polydactyly and external ear malformations. However, four-dimensional color ultrasound is not omnipotent. For example, it cannot detect deafness and cataracts in newborns. Pregnant women should understand the importance of four-dimensional color ultrasound screening and undergo four-dimensional color ultrasound examination at the time prescribed by the doctor.
