How many days of pregnancy can be detected by test strips

Although women will have a series of early pregnancy reactions after they become pregnant, this cannot be used as a criterion for testing whether they are pregnant. Generally, they need to use pregnancy test strips for testing. If the pregnancy test strip shows a positive result, it means they are already pregnant, but the test strip test needs to grasp the best time. So how many days does it usually take to detect pregnancy using a test strip?

1. 7 to 10 days of pregnancy and can be detected with test strips

The basic principle of pregnancy test strips is mainly to use the component of human chorionic gonadotropin in women's body. Generally, when you are 7 to 10 days pregnant, or when your menstruation is delayed for ten days or more, you can use the pregnancy test strips for testing. If the pregnancy test strips show two green lines, it can be basically judged that you are pregnant. If it is one green line, it means you are not pregnant yet.

2. How to use pregnancy test strips

When using pregnancy test strips to detect pregnancy, it is best to use morning urine for the test, which will greatly increase the success rate. This is mainly because morning urine is relatively extracted and contains higher levels of hormones, which can almost achieve an accuracy rate of 98%. However, if you have been pregnant for some time, using urine at any time can provide a more accurate diagnosis. The actual test method is very simple. After collecting appropriate urine, insert the test strip and wait for about five minutes.

3. What to check during pregnancy

After a woman becomes pregnant, she can only use pregnancy test strips to basically detect the pregnancy status, but it cannot be 100% accurate. Therefore, she must go to the outpatient gynecology department for basic abdominal B-ultrasound, vaginal color ultrasound and blood tests. This can not only accurately determine whether she is pregnant, but also check the actual growth and development status of the fetus, and can rule out ectopic pregnancy, threatened abortion and ectopic pregnancy.
