First things first, pregnancy test strips work by detecting pregnancy hormone from a woman's urine sample. This hormone, called hCG or human chorionic gonadotropin, is a glycoprotein hormone that is produced by the developing embryo during pregnancy.
After six days of conception, the fertilised egg implants the uterus and in the process produces hCG. However, it is evident from many studies that in ten percent of women implantation occurs even after the first day of missed period. But, in all the cases, the level of hCG builds up rapidly everyday.
While you are waiting to read your pregnancy test results you will notice a coloured solution moving across the test area towards result area. This migration is normal and indicates that test is progressing correctly. Wait for few minutes (according to time mentioned in the manual).
When checking for pregnancy with the help of a pregnancy test kit, it is important for you to follow the instructions as mentioned on the label.
