A pregnancy test with two bars and one dark and one light may be pregnant, but it is not 100% pregnant. A weakly positive test for human chorionic gonadotropin in the presence of recent sexual activity may indicate pregnancy. However, the sensitivity of the pregnancy test is poor, and if there is a history of ovarian tumors, human chorionic gonadotropin may also be elevated, resulting in a pregnancy test with two bars, one dark and one light, and therefore not 100% pregnant. To detect pregnancy, the test value of the first urine test in the morning is the most accurate. After the urine is concentrated, it is able to detect the hormone level, which is more accurate than the value of human chorionic gonadotropin increased in other urine segments. For a definitive diagnosis, it is recommended to visit a hospital to test blood HCG and ultrasound for a definitive diagnosis.
