Pregnancy can be detected through early pregnancy test strips, which have high accuracy and are also very convenient. As long as urine is collected at home for testing, it is sufficient. A positive result after testing indicates pregnancy, while a negative result indicates non pregnancy. Some women also test weakly positive. What is the probability of pregnancy if they test weakly positive?
The probability of weakly positive pregnancy is also relatively high, but it may be due to the short duration of pregnancy, which is not very obvious. At this time, a blood test for HCG can also be performed to accurately diagnose pregnancy.
A weak positive result in early pregnancy test strips may be due to the early testing time. Some women test before their menstrual cycle stops for one week, when HCG secretion is not very high, so the detection concentration is not enough, which can easily lead to weak positive results. It may also be due to urine dilution. Drinking too much water before pregnancy testing can dilute urine and lead to low HCG concentration, which can also easily result in weak positive results. It may also be caused by expired test strips or moisture.
In addition to using early pregnancy test strips, pregnancy can also be detected through B-ultrasound examination. The time for B-ultrasound examination of early pregnancy is usually about a week after menstruation is delayed. You can go to the hospital for B-ultrasound examination to see if you are pregnant. If you can see a pregnancy halo under B-ultrasound, it means you are pregnant. It can also be tested for HCG through blood tests, usually taken at the hospital about 10 days after sexual intercourse.
