Can Blood Tests Detect Pregnancy and False Pregnancy?

Blood tests can detect pregnancy and false pregnancy. The principle of blood test for pregnancy is to detect the level of HCG in the blood. False pregnancy refers to the situation where a woman believes she is pregnant, but in fact, she is not. It is often accompanied by symptoms such as amenorrhea, nausea, and vomiting. Medical examinations, such as negative results on early pregnancy test strips, normal levels of blood HCG and progesterone, and absence of a gestational sac on ultrasound, can confirm the diagnosis of false pregnancy. An elevated level of HCG indicates pregnancy. To determine whether it is an intrauterine pregnancy or an ectopic pregnancy, an ultrasound examination is needed. If the pregnancy is generally uneventful without abdominal pain or vaginal bleeding, an ultrasound examination can be considered six weeks after amenorrhea. If there are symptoms such as abdominal pain or vaginal bleeding, immediate medical attention is required. False pregnancy occurs often in women who are under high mental stress and constantly desiring pregnancy but cannot conceive. It is a psychological phenomenon that produces symptoms similar to pregnancy, such as delayed menstruation, nausea, vomiting, and even the perception of fetal movements and abdominal enlargement. Despite these symptoms, early pregnancy test strips will show negative results, blood tests will reveal normal HCG levels, and ultrasound examination will not show any enlargement of the uterus or the presence of a gestational sac or fetus. If false pregnancy is suspected, it is important to undergo relevant examinations at a formal hospital to confirm the absence of pregnancy. It is recommended that women divert their attention, relax, participate in outdoor activities, maintain a healthy diet, ensure adequate sleep, and seek psychological counseling if necessary to regulate their endocrine function.
