The presence of hCG or Human Chorionic Gonadotropin in urine signals a woman that she is pregnant. This hormone does not only serve as an indicator but it also increases and maintains the production of progesterone, a female hormone that prepares the uterus for the growing fetus. As the pregnancy progresses, hCG hormone also increases; however, the production of this hormone will drop at 12 to 16 weeks of pregnancy.
Women expecting for a baby can use pregnancy test kits during the peak levels of hCG production. These test kits are said to give 99% accuracy that is why, if results are negative, pregnancy is most likely not happening. Knowing how pregnancy test kits work is very helpful as it provides you an assurance whether you are pregnant or not. To further acquaint you with pregnancy test kits, it is best to know the answers to commonly asked questions.
