Pregnancy test strips are a commonly used method of pregnancy testing nowadays, but there are still some concerns when using them. Especially for female friends who have experienced ectopic pregnancy, they are even more at a loss during pregnancy testing and do not know what kind of results are normal. So, will ectopic pregnancy test strips be strongly positive?
Ectopic pregnancy test strips can detect strong positive results. If the HCG test of the early pregnancy test strip is positive and no gestational sac is found in the uterine cavity according to the results of the abdominal ultrasound examination, then the possibility of ectopic pregnancy should be considered. But first of all, it is necessary to rule out the possibility that the gestational sac is too small to be detected, so if no gestational sac or other abnormalities are found, a follow-up examination should be conducted after 7 days.
The principle of early pregnancy test strip detection is that human chorionic gonadotropin (HCG) is a glycoprotein produced by the placenta during pregnancy, which can be eliminated from the body through the glomerulus. Therefore, measuring HCG in urine is a reliable indicator for diagnosing pregnancy. The early pregnancy test strip adopts nano colloidal gold technology and applies chromatographic double antibody sandwich method to detect the concentration of HCG in urine and determine whether pregnancy is possible.
The complete human chorionic gonadotropin (HCG) is produced entirely by the syncytiotrophoblast layer of the placental chorion. Its main function is to stimulate the corpus luteum, which is conducive to the continuous secretion of estrogen and progesterone, promoting the formation of uterine decidua and facilitating the growth and maturation of the placenta. HCG secretion begins around 6 days after fertilization and reaches its peak at 60-70 days. Value increases rapidly in the first 8 weeks of pregnancy to maintain the pregnancy. After approximately 8 weeks of pregnancy, HCG gradually decreases and reaches a relatively stable level at around 20 weeks.
