When many of us think we are pregnant, our first reaction is to go to the pharmacy to buy a pregnancy test strip to test whether we are pregnant or not. However, after buying it and testing it, we find that we don’t understand what it shows on the test strip at all. We don’t know what it means to be pregnant. So, how does the test strip show that we are pregnant?

How does the test paper show that you are pregnant?

In the early stages of pregnancy, the test paper can detect an increase in blood cell HCG and show a positive result. There may be a situation where the ultrasound cannot be taken. Under normal circumstances, the embryo, fetal heart and fetal heartbeat fluctuations can be seen at 8 weeks of pregnancy, and the yolk sac can be seen at 6-7 weeks of pregnancy. You should pay attention to follow-up consultation in time. Your test paper shows pregnancy: There are two possibilities. One is that you are pregnant, but the embryo implants late, so it cannot be shown on the ultrasound. The second possibility is ectopic pregnancy, and the ectopic pregnancy test paper can also show positive information. Therefore, it is recommended to have another ultrasound check-up one week later. If you are pregnant, the gestational sac will be displayed. If you experience abdominal pain during this period, go to the hospital as soon as possible.

If you are pregnant, the early pregnancy test paper should show pregnancy one week after the menstrual period. The principle of the test paper is to test the HCG value, that is, the value of hcg gonadotropin in the body. Human chorionic gonadotropin (HCG) is a glycoprotein growth hormone produced by the embryo of a pregnant woman and is present in large quantities in the urine of pregnant women. There is almost no HCG in the urine of non-pregnant women. HCG usually appears in the urine a few days after the embryo implants, and it must reach a certain amount to be detected. Therefore, for women with normal menstruation, HCG can only be detected in the urine after the menstruation is delayed for one week. Women with long menstrual cycles or abnormal ovulation can only be tested after 40-44 days of amenorrhea. (HCG value can also be measured through blood test, and it is much more accurate). Neither too early nor too late will have good results. Improper operation of the test paper may result in a positive or false negative result. Using early pregnancy test strips for pregnancy testing is only a basic test and should not be used as the final test result. Going to the hospital for a comprehensive and special examination is the most reliable and reassuring way.

How to use pregnancy test paper

Before using a pregnancy test paper, first check the expiration date of the product to make sure it is still within the validity period. For pregnancy test papers that have been purchased for some time, don't forget this point in particular, so as to avoid inaccurate pregnancy test results due to the use of expired products. If you put the pregnancy test paper in a humid or hot environment (such as in the shower), it may become ineffective, so it is best to throw it away and buy a new one.

Before using a certain type of pregnancy test paper, it is best to read its product introduction first, because the usage methods of pregnancy test papers of different brands will be different. Some pregnancy test paper products require women to use a urine cup to collect urine, and then use the burette attached to the product to draw a small amount of urine onto the test paper. Other products require you to urinate directly onto the test stick. Some pregnancy test paper products say that both methods are possible.

For the most accurate results, women should take a pregnancy test using their first urine output in the early morning. The pregnancy test paper can detect human chorionic gonadotropin (hcg) which is often contained in urine. This hormone is produced by fetal tissue during pregnancy. The concentration of morning urine is higher, so it will contain a large amount of human chorionic gonadotropin, which will make the pregnancy test results more accurate.
