evidence: A pregnancy test with salt requires basic ingredients, including morning urine and salt. All you need to do is mix your morning urine and salt in a clean bowl and then wait for a few minutes. If a mixture changes its appearance and turns milky or contains foam, the pregnancy test result with salt is positive. If there is no change in the colour, it suggests no possibility of pregnancy. [...] Also, there is no convincing evidence backing the theory related to the hCG and salt reaction. Interestingly, before the advent of modern pregnancy tests available over the counter, not all women would use home-based salt pregnancy tests much to get an idea about pregnancy, let alone talk about the reliability of this test. Therefore, the accuracy related to pregnancy tests with salt is probable. [...] In salt pregnancy test positive results, urine turns "cheesy" or "milky" after getting mixed with salt, indicating the possibility of pregnancy. It is the hormone named "human chorionic gonadotropin" present in urine post the implantation of the embryo in the uterus that reacts with salt. This is indeed the main reason for the change of colour, indicating the possibility of pregnancy.
