Probability of false positive pregnancy test

Using early pregnancy test strips to check whether you are pregnant is the most common way for women to self-test. So are early pregnancy test strips 100% accurate? Will a positive result appear? That is, when a female friend takes an early pregnancy test and the pregnancy test paper shows positive, but she is not pregnant, does the early pregnancy test also show a positive result? What is the chance of a positive early pregnancy test?

Using early pregnancy test strips is a way to check whether you are pregnant, which is now quite common. The pregnancy test paper showing positive information is also a situation that many female friends have encountered. In reality, false pregnancy does occur, which makes many female friends confused.

Regarding the statement that the early pregnancy test paper has a positive result, it is generally caused by a comprehensive "unbalance" of physiology and psychology, which affects the hypothalamus-pituitary and pituitary nerve dysfunction, resulting in the appearance of a positive early pregnancy test paper. Let's explain in detail the reasons for a positive early pregnancy test paper.

What is the reason for a positive early pregnancy test? This condition may also be a false pregnancy. Physiologists believe that false pregnancy is a comprehensive "deficit" of physiology and psychology. After getting married, some women, eager to have children, often compare themselves with their sisters who are getting married at the same time. When they see others getting pregnant, they become envious and anxious. When you think about it day and night or want something that is out of reach, the cerebral cortex will produce obvious "anticipation" excitation foci, which will affect the hypothalamic pituitary gland and pituitary gland's neurological dysfunction, and finally cause amenorrhea. After menopause, under the influence of estrogen in the body, fat in the lower abdomen will also accumulate. As a result of their psychological desire to get pregnant, they think they are pregnant, which leads to the "pregnancy" reaction of anorexia, eclipse and nausea. For some women, under the psychological factor of "simulated pregnancy", the body's hormones and androgen will be unbalanced, and they may even develop butterfly spots on their cheeks and feel "baby movement" in their stomachs. This is actually a psychological factor.

Generally speaking, if a woman does a self-test for pregnancy at home, without any external guidance, the test results are generally only 50% to 75% accurate. A positive result on an early pregnancy test may be caused by emotional anxiety or other factors. If such tests are done in the laboratory in the presence of a doctor, the doctor can ensure that the pregnancy test paper works normally, and women can actually use the pregnancy test paper correctly according to the instructions, the test accuracy may be close to 100%.
