How many days does it take to detect early pregnancy?

Early pregnancy test paper is a product designed by us to be a convenient way for women to test whether they are pregnant. In general, there are two kinds of test results of early pregnancy test paper: put urine into the test hole on the pregnancy test paper, if there is a line in the contrast area of ​​the pregnancy test paper (some pregnancy test paper are bright red, some pregnancy test paper are dark blue), the expression is negative, indicating that you are not pregnant; on the contrary, if there is an obvious line in the test area, the expression is positive, indicating that you are already pregnant.

This type of test has the advantages of being rapid, convenient, flexible and highly specific. Early pregnancy test strips can only be used as a preliminary screening test. Don't trust them too much, because early pregnancy test strips may result in positive or false negative results.

The principle of using early pregnancy test strips for pregnancy testing is to test the HCG value, that is, the value of human chorionic gonadotropin in the body. This type of hormone is produced by the embryo and usually appears in the urine immediately after a few days of pregnancy. However, due to the small amount, it is not easy to test it at the beginning, and it will become increasingly obvious from 10 to 14 days. (HCG values ​​can also be measured through blood tests, and are much more accurate). Neither too early nor too late will have good results.

Test results

1

Negative: A dark purple line appears in the test area (comparison line C), indicating that you are not pregnant.

2

Positive type: Two dark purple lines appear in the test area (comparison line C and test line T), indicating pregnancy. The color intensity of the test line at different stages of pregnancy changes with the change of HCG concentration.

3

Invalid: No dark purple line appears in the test area or only one dark purple line appears in the test area (test line T line), which means the test is unsuccessful or the pregnancy test paper is invalid and should be tested again.

Frequently asked questions

Diluted fluid in urine. Drinking too much water may dilute the urine and cause a false negative result.

Performing experiments in the morning and at night may have some impact on the results. The highest HCG value is usually found in the urine in the morning, so many instructions recommend testing in the morning, but this is not absolute.

During the test, pay attention to the length of the pregnancy test paper that is immersed in urine. Sometimes the length of time that urine soaks into the test strip is too long to make the test result indistinguishable.

Do not rely on test results to determine whether you are pregnant if you have recently been pregnant. Because HCG can remain positive for a long time after the termination of pregnancy (after childbirth, spontaneous abortion and artificial abortion).
