After becoming pregnant, women need to pay attention to their HCG levels. Women who successfully conceive have a rapid increase in HCG levels in their bodies, and may even experience a doubling the next day. When conducting a pregnancy test, the HCG values in a woman's urine and blood are measured. So, can HCG accurately determine how many days of pregnancy?
When a woman is pregnant, the number of days of pregnancy cannot be determined by the HCG value. This is because every woman's physical condition is different. Although there is an increase in HCG values after pregnancy, the magnitude of the increase varies from person to person, and the normal range of HCG values is large, so it is impossible to determine the number of days of pregnancy through HCG.
If a woman successfully becomes pregnant, early pregnancy can be detected by blood HCG after 10 days of sexual intercourse. Blood HCG testing does not require fasting, as it determines pregnancy based on the HCG levels in a woman's blood. The levels of other elements in the blood have no effect on HCG.
Compared to traditional urine HCG testing, blood HCG testing is more accurate, with a lower probability of error, and the detection time is also slightly earlier. If women are not in a hurry, they can also purchase pregnancy test strips for testing half a month after sexual intercourse. However, when using pregnancy test strips, it is best to use morning urine to obtain more accurate results.
