Currently the more sensitive pregnancy test, hcg (human chorionic gonadotropin) value of 25IU / L or more, the pregnancy test is printed. A pregnancy test is used to determine whether or not you are pregnant by checking for an increase in human chorionic gonadotropin in the urine. Two bars appear on the pregnancy test when it is positive. The sensitivity of pregnancy tests varies depending on the manufacturer. Usually, a hcg (human chorionic gonadotropin) value of 25 IU/L or more will indicate a pregnancy. Be careful to do a good recheck. After successful fertilization of the egg, it takes about less than 1 week for the human chorionic gonadotropin to reach 100 IU/L. Do not be nervous, a positive test in a woman with regular menstruation after a delay of more than 7 days means pregnancy. More anxious to know the result, if necessary, you can go to the hospital to draw blood to check the hcg value to determine whether you are pregnant.
