The working principle Pregnancy Test Tools
The ovum gets fused with a sperm in the fallopian tube to form a zygote. The zygote undergoes cell division for about 5-6 days. After this period, the zygote leaves the fallopian tube and moves to the uterus, where it gets implanted and undergoes further stages of pregnancy development.
When the zygote gets implanted in the uterine lining, a structure called placenta is formed. It is the connection between the growing fetus and the mother. The placenta produces a glycoprotein hormone known as human chorionic gonadotropin or hCG. The hCG appears to form soon after conception, and its concentration keeps rising during the early stages of maternity.
All these facts makes hCG an excellent marker for the pregnancy tests. The minimum cutoff of hCG level to get detected by the pregnancy tests is 20 milliliter per liter of urine. Some pregnancy hormone tests are sensitive enough to detect such a low concentration of hCG in your body. However, many pregnancy test kits may not be sensitive to this level. But most of them can easily detect the presence of hCG at about 50 milliliter per liter of urine.
