Kit) test principle: pregnancy test is a kind of in vitro diagnostic (IVD) products, also belongs to the scope of management of medical devices. The so-called test is to use the pregnancy test stick to detect Human Chorionic
Gonadotropin (HCG) in the urine, which is a prohormone secreted by the placenta of a pregnant woman and distributed throughout the body with the blood, thus acting on the target organs, and a certain concentration of HCG exists in the urine.Currently, most of the pregnancy test products on the market are not suitable for use in the urine. The majority of pregnancy tests on the market use the colloidal gold method, which is based on the principle of double antibody sandwich to qualitatively or semi-quantitatively detect HCG in urine to determine whether or not you are pregnant. It is important to note that these
products are not 100% accurate, and certain diseases can cause elevated levels of HCG in the body, resulting in false-positive results.
